Syllable structure matters

You know, I can't remember who I was talking to about this recently or why we got on to the topic, but I have always done my best to educate language teachers (and learners, for that matter) about the importance of syllable structure and phonotactics in learning how to pronounce a new language.

I am, of course, usually coming at it from the angle of someone pronouncing English.

As you doubtless know, accents such as Standard Southern British English (SSBE) have up to three consonants at the start of a syllable (onset consonants) and four consonants at the end (coda consonants), and a syllable usually has a vowel as its peak. The structure of the basic SSBE syllable can therefore be described as follows:

(CCC)V(CCCC)

I'd recommend reading Roach (2009) chapter 8 or Cruttenden (2008) section 5.5 for a full description of what clusters are possible in syllable onsets and codas in SSBE. There's also a nice description on the Macquarie Linguistics pages. The main point I want to make here is that not all languages have syllables which are as complex as English (and English does not have the monopoly on complexity), and this is what can lead to problems with pronunciation as much as not being able to produce a sound.

The thing which always surprises me - and perhaps it shouldn't - is that teachers of English from other language backgrounds often know nothing about the phonology of their own language, and so do not understand that a learner's problem with pronouncing a sound in a particular position in the syllable is unlikely to be about not being able to produce the sound per se but that the learner's language does not permit certain sounds in certain positions in the syllable. If, for example, a learner is from a Chinese language background and that language only permits a zero-coda (i.e., no consonants at the end of syllables) or only a nasal of some description in the coda, pronouncing any other consonant at the end of a syllable may be difficult, and pronouncing clusters is going to be an extreme challenge.

In addition, learners have different strategies for dealing with clusters. Some learners (e.g., Japanese) will insert vowels between consonants in a cluster - this process is known as vowel epenthesis - in order to preserve as many consonants as possible. By comparison, Chinese speakers will often elide consonants in order to be more similar to Chinese syllable structure and number. Here's a favourite comparison of mine: In Japan, MacDonald's, which is /məkˈdɒnəldz/ in SSBE, is known as "ma-ku-do-na-ru-do", but in Hong Kong it is known as "mak-do-nau", with a strongly glottalised and unreleased [k] in the first syllable. Japanese tends to preserve the consonants but Cantonese preserves the number of syllables.

In World Englishes, we often see patterns of syllable structure influenced by a speaker's L1 or the indigenous language(s) of the region in which English has been adopted. This may be why speakers of many varieties of English around the world drop third-person singular "-s"; the meaning of it is retrievable from the context, and it's a rather superfluous inflection which is likely to be dropped anyway in complex codas in many L2 Englishes. 

Does it matter that clusters are simplified? Yes, it does, if intelligibility and therefore meaning is compromised. One is unlikely to be misunderstood if leaving off third-person singular "-s", but it becomes more of a problem in other contexts; my understanding of a Hong Kong English pronunciation of MacDonald's (I'd asked what the student's favourite things were) was that the speaker had said Madonna, thanks largely to the lack of consonants at the end of the word.

What can teachers do about this? First, one needs to be aware of the syllable constraints of the L1 of the learners you are going to be teaching, so you have an idea of whether they are used to complex syllable onsets and codas to start with. If not, chances are learners will be able to produce singleton consonants and some clusters in onset position with little difficulty, but codas are always more problematic.

One strategy, if coda consonants are a problem, is to try to "slide" the coda consonants into the next word; this doesn't always work, but it can also help learners with listening if they can understand that speech is a stream rather than a string of discrete words, and so it may well sound like coda consonants belong to the next word. For example, in a phrase such as "MacDonald's is my favourite", one could slide the final /z/ of MacDonald's into the start of the word "is" and it would then be a little more straightforward for the listener to retrieve.

Flipping phonetics

I am so sorry I've not posted for a while; it's been a hectic term!

One of the reasons it's been hectic is because I've been trying a different method of delivering some of my English phonetics and phonology classes and that - as always - entails preparation which takes TIME ... but time well spent which has been worth it.

I first heard about the flipped classroom from my friend and colleague Dr Patricia Ashby who is now an Emeritus Fellow of the University of Westminster. You may know Patricia from her excellent books Speech Sounds and Understanding Phonetics. She presented "Flipping Phonetics" at the Phonetics Teaching and Learning Conference at UCL in 2011; you can read the paper by clicking HERE, and will notice that the results for the topics Patricia "flipped" were very impressive.

The flipped classroom basically involves presenting what would normally be lecture content via vodcasts which the students watch ahead of the class, thus allowing more time in the actual class itself for practical work. This approach works well in the sciences where a lot of practical work is needed for students to progress, and Patricia had noticed how it was also suitable for phonetics, which also requires a lot of rehearsal of skills and time for class discussion of issues.

I had wanted to try this for a while as I have been becoming increasingly concerned that the growing number of students I have in my class meant that I had less time to spend with each of them and that it was difficult to support individual student needs. Thanks to a small grant from the University of Reading's "Partnerships in Learning and Teaching" (PLanT) pilot scheme, I was able to buy some software to do video capture of my desktop which enables me to record video and audio of me narrating my way through my lecture slides. I then post these on our virtual learning environment, Blackboard, for the students to view ahead of class.

The PLanT scheme also enabled me to work with students to produce materials for the post-exams period at Reading to scaffold first year students' learning in preparation for the English phonetics and phonology module in Year 2. You can read about this HERE and HERE (see p. 79).

One set of the vodcasts is on YouTube and I've posted them below if you'd like to take a look.  We follow Peter Roach's English Phonetics and Phonology on this course, and this class presents material from chapters 15-17. In it you will see some embedded YouTube clips and also the excellent programme RT pitch which is available for download from UCL's wonderful phonetics and speech resources.

I would value feedback on these videos (aside from the fact that I say "so" a lot!) either at the end of this message or on the YouTube pages themselves via my channel (be warned: also contains some videos of one of my bands, Crimson Sky).

Students' responses so far have been very positive. They mention how appreciative they are to have more time in the class to work on practical skills. They also indicate how presenting material this way aids independent learning and allows students to take notes at their own pace, and they can of course return to these videos when it comes to exam revision; our exams are in May/June so there is a lot of time to forget the content. One student has written a blog post of her own about this (lots of other good stuff on there!), and another comments: "Your delivery and humour makes them very interesting and engaging." They have asked for other tutors to adopt this method and I hope some of my staff will consider it.

Last year I was disappointed to see that the average overall marks among undergraduates for the dictation test we do at the end of term had dropped by around 11 percentage points. I usually expect the average to be in the mid-to-low 60s; the previous year's average had been around 66%.  I'm just about to mark the transcription tests this year and will report back on whether they have improved with an update to this post.

UPDATE #1: I've marked 20 out of 59 scripts and can report that the current average is **over 15 percentage points higher***. Watch this space ...

UPDATE #2: Having finished the marking, I can confirm that the average is up over 10 percentage points on last year's dictation test scores. Although not quite as impressive as 15%, it's still pretty darned good!

Intonation and train announcements

This is a post about the intonation of announcements on trains in the UK. 

I didn't actually think it was worth posting on this topic until one of my students on the UCL Summer Course in English Phonetics mentioned that he thought the intonation was odd - and he was talking particularly about a feature which I had noticed and thought amusing.

I was returning to Reading on the South West Trains London Waterloo service one evening when I noticed two things that interested me: first, the company who made the in-train announcements had chosen a falling-rising tone rather than a rising tone for certain functions; and second that the falling-rising tone was used in some unexpected places.

Excuse me while I explain a few things about intonation in standard British English, southern accent. This is taken from a chapter I wrote a while ago (Setter 2005) on Discourse Intonation and adopts that framework (see e.g. Brazil et al. 1980; Brazil 1997). There are four central elements to discourse intonation: tone, key, the tone unit and tonicity. I'm going to focus on tone here; readers with interest in the subject should seek the publications mentioned for a fuller introduction.

Tone refers to the major pitch movement(s) in an utterance. Brazil et al. (1980: 13) distinguish between five tones: falling, rising, falling-rising, rising-falling and level. The falling and falling-rising tones “embody the basic meaningful distinction carried by tone”, whereas the other three “can usefully be seen as marked options, understood and meaningful in contrast” (Brazil et al. 1980: 13).

The following example is given to show the contrast between two utterances using the two basic tones, falling and falling-rising (Brazil et al. 1980: 13); I have used  to indicate falling and  to indicate a falling-rising, and // indicates a tone unit boundary (or intonational phrase boundary):

(1)         // when I’ve finished Middlemarch // I shall read Adam Bede //

(2)         // when I’ve finished Middlemarch // I shall read Adam Bede //

Other meanings notwithstanding, by using the falling-rising tone on Middlemarch and the falling tone on Bede in example (1), the speaker is showing that he/she believes the listener already knows the speaker is reading Middlemarch, but does not know the next book the speaker intends to read is Adam Bede. By contrast, in example (2), it is believed that the intention to read Adam Bede is known, indicated by the falling-rising tone, but not the fact that the speaker is reading Middlemarch at the moment, indicated by the falling tone. The use of specific tones therefore indicates what the speaker believes either to be common ground in any utterance, be it general knowledge of the world or information mentioned earlier in the same piece of discourse or some other context, or unknown – whether information is given or new.

Brazil et al. state that “all interaction proceeds, and can only proceed, on the basis of the existence of a great deal of common ground between participants” (1980: 15). Given information, or common ground, is indicated by what Brazil et al. call “referring” tones, and new information is indicated by “proclaiming” tones (1980: 15). The falling tone is therefore the default proclaiming tone, and is given the symbol p, which is placed at the beginning of the tone unit. The falling-rising tone is default referring tone, and is indicated by the symbol r. The nucleus, referred to as the tonic syllable, is capitalised and underlined; the two examples above could therefore be represented as follows:

(1a)       r when i’ve finished MIDdlemarch // p i shall read adam BEDE //

(2a)       p when i’ve finished MIDdlemarch // r i shall read adam BEDE //

The choice of tone used by a speaker is, then, dependent on the speaker’s evaluation of “the relationship between the message and the audience” (Brazil 1980: 18) – whether the speaker believes information in the message to be given or new. From this point of view, the speaker might be assuming common ground which does not exist, and therefore erroneously using referring tones, or using proclaiming tones where the information is, in fact, already part of the common ground.

The other tones mentioned are rising, rising-falling and level. The rising and rising-falling tones are variants of the r and p tones respectively; the symbol for the rising tone is r+, and for the rising-falling tone, p+. The level tone is symbolised with an o.

An r+ tone is used to reactivate background material. Brazil et al. give the following example (1980: 53):

(3)         Where’s the typewriter?

(3a)       r in the CUPboard // (where it always is)

(3b)       r+ in the CUPboard // (why don’t you ever remember …)

In (3a), the fact of the typewriter being in the cupboard is deemed by the speaker to be “vividly present in the background”, whereas in (3b) the speaker is indicating that the listener has to be reminded of what should be common knowledge.

Use of the r or r+ tone can, therefore, show the relationship between speakers in a conversation. The r+ tone is used by a speaker who is assuming some kind of dominant role in the conversation, and is commonly used by teachers in teacher-student interactions, doctors in doctor-patient interactions, or those giving directions or instructions to someone who (it is assumed) has no prior knowledge. As Brazil et al. point out, a patient who starts a doctor-patient interaction with an r+ tone will sound rather aggressive (4); an r tone is usually used (5) (examples from Brazil et al. 1980: 16 & 54). 

(4)         r+ i’ve COME to SEE you // p with the RASH // r+ i’ve GOT on my CHIN //

(5)         r  i’ve COME to SEE you // p with the RASH // r i’ve GOT on my CHIN //

(Where there are other stressed syllables preceding the tonic syllable, these are capitalised but not underlined in this system.)

The p+ tone (rising-falling), like the p tone, is used to indicate that the information is new, but with the additional meaning of being surprising, disappointing or horrifying to the speaker also – the speaker is adding “to his own store of knowledge” (Brazil et al. 1980: 56). It is noted that the p+ tone tends to be used by a dominant speaker.

The level tone, symbolised o and referred to as the “oblique” tone, is used to indicate that the speaker considers he/she has not arrived at the potential completion point of an utterance (Brazil et al. 1980: 88), but it can also show that the speaker is not very involved in, e.g., reading a passage.

OK, that's the end of the section from Setter (2005). Are you still with me?

On South West Trains, some of the announcements are something like the following:

(6)         This is the South West Trains service from London Waterloo to Reading, calling at Vauxhall, Clapham Junction, Putney, Richmond, Twickenham, Hounslow, Feltham, Ashford, Staines, Egham, Virginia Water, Longcross, Sunningdale, Ascot, Martin's Heron, Bracknell, Wokingham, Winnersh, Winnersh Triangle, Earley and Reading.

(7)         The next station is Sunningdale.

(8)         This station is Sunningdale.  The next station is Ascot.

These announcements are clearly made up of "slots" - e.g.:

(6a)       This is the (slot 1) service from (slot 2) to (slot 3), calling at (slots 4, 5, 6 ...) .... and (slot 7).

(7a)       The next station is (slot 1).

(8a)       This station is (slot 1).  The next station is (slot 2).

In order to do this, the company producing the announcements has to have some kind of idea of how intonation works. Among other things, we are dealing with a list in (6) and (6a), so some slots will have an intonation pattern which indicates the speaker has not got to the end of the list, requiring a referring (r) tone of some kind - i.e., slots 2, 4, 5 and 6 in (6a) - and a pattern which indicates the end of a list, requiring a proclaiming (p) tone of some kind - i.e., slots 3 and 7 in (6a). The company has therefore recorded two versions of each town/city at which the train stops, one with an r tone and one with a p tone. In (7a), the p tone is used in slot 1 as this is a statement.

The intonation patterns are as follows:

(6b)         r this is the SOUTH west TRAINS service // from LONdon waterLOO // p to READing // r calling at VAUXhall // r CLAPham JUNCtion // PUTney // RICHmond // TWICKenham // HOUNSlow // FELtham // ASHford // STAINES // EGham // r virGINia WATer // LONGcross //  SUNningdale // AScot //  MARtin's HERon // BRACKnell // WOkingham // WINnersh // r WINnersh TRIangle // EARley // and READing //

(7b)         the NEXT station // p is SUNningdale //

(8b)         r THIS station // r is SUNningdale //  r the NEXT station // p is AScot //

Can you spot the things which amuse me?

First, as the announcement being made is authoritative, I would expect the referring tone in the list to be a rising tone (r+) rather than falling-rising (r). This was what the very observant non-native English-speaking student asked me about in class this year. One could argue that commuters take this train every day and so the information is already "vividly present" in the background somehow ("this train always stops at these stations and you know it" - see 3a above), but I'm going to dismiss that.

Second, in (8b), the company who selects which spoken version of the town/city goes into which slot has chosen an r tone for "Sunningdale" - i.e., (8a) slot 1. I assume this is because there is another town/city about to be mentioned later in the announcement (slot 2 - this correctly has a p tone on it) and so the company sees it a type of list. However, whenever I hear this it makes me laugh, because using an r tone here makes it sounds like a surprise that one has arrived in e.g. Sunningdale.

(9)         This station is Sunningdale  ..??
              ... What??? I was expecting Longcross! I must have fallen asleep! Blast!!

What should it be on "Sunningdale" in slot 1 (8a)? A falling tone (p), of course ("this is definitely Sunningdale and you don't have to be in any doubt about it").

So, next time you are on trains in the UK, listen to see what intonation patterns are being used. Has the automated system of putting things in slots in announcements worked? Do let me know!

(Don't get me started on nucleus placement on prepositions ...)

The International Phonetic Alphabet

I was recently asked to contribute some history and other information on the IPA chart for Babel Magazine's fourth issue. The text below is the unedited version of what appears, with references. I have been given permission to post this to my blog.
--
The International Phonetic Alphabet represents the sounds of all the world’s documented languages. The first published version of this chart can be found in Passy (1888) and appeared in a journal called The Phonetic Teacher (or Dhi Fonètik Tîtcer). This speaks a lot to its origins, as the International Phonetic Association (IPA) itself was inaugurated as the Phonetic Teacher’s Association in 1886 which was mainly involved with teaching English (IPA 1949, p. 2 of cover). During the first two years of the association, and as more than one script was in use, it was decided by its members to establish a single alphabet which could be applied to the description of all languages. Since Paul Passy’s publication of the first chart in 1888, the association has worked tirelessly to improve the alphabet and there have been several published revisions. The alphabet itself is “on romanic basis” (IPA 1949, p. 1), meaning it uses a script which derives from Roman characters rather than e.g. Cyrillic (Russian), Arabic or other written traditions, and is presented by the Association as “a consistent way of representing the sounds of language in a written form” (IPA 1999, p. 3).
The International Phonetic Alphabet (2005 revision)*
The current revision of the IPA chart (above) starts with a large table showing consonant sounds, or phones, made on a pulmonic egressive airstream (i.e., with air from the lungs). Place of articulation (POA) is indicated by which column a symbol is located in. The passive articulator is usually indicated, i.e., the part of the oral cavity which remains in place while the active articulator – often the tongue – moves towards it; e.g., if a sound is labelled “alveolar” it means the tongue moves towards the alveolar ridge. Manner of articulation (MOA) is indicated by row. Where voiceless and voiced pairs of consonants are given, the one on the left is voiceless. The usual way of describing a consonant is to use a VPM label, where VPM stands for “voice place manner” – so [t] is a voiceless alveolar plosive.
This table is followed by non-pulmonic sounds – clicks, implosives and ejectives – below and to the left, with the vowel chart to the right. The vowel chart represents cardinal values for vowels which can be used as a reference to describe vowel sounds in languages. Symbols are placed on a trapezium which represents the vowel space; this space is in fact very small, with “front” vowels being articulated with the front of the tongue raised to various degrees in proximity to the hard palate, and “back” vowels involving the back of the tongue being raised in proximity to the velum. It is usual to describe vowels in terms of height, backness/frontness and lip rounding – so e.g. [i] is a close front unrounded vowel.
Beneath the non-pulmonic sounds are “other”consonantal symbols; these are ones which do not appear in the main chart because they have two POAs, two MOAs, or cannot be otherwise accommodated.  E.g., [w] has both lip rounding and a movement of the back of the tongue towards the soft palate, so is labial-velar and therefore classed as a double articulation; [t͜s] is an affricate, which involves a plosive followed by a fricative both produced at the same POA (i.e., homorganic) with the same voicing; alveolo-palatal fricatives [ɕ] and [ʑ] are not on the main consonant chart because that region simply cannot accommodate any further symbols.
Beneath this list is a table of diacritics which allow the sounds on the chart to be modified further. For example, the symbol [t] can be modified to represent a voiceless dental plosive by adding the dental diacritic to give [ t̪ ].
Under the vowel chart is a list of symbols for representing suprasegmental information, i.e., phonetic features above the level of individual speech sounds.  Here we can find stress marks, length marks, syllable-division marks and suprasegmental boundary markers and, below these, symbols for tones and word accents.
Although the alphabet largely achieves what it sets out to do, there are a number of issues which arise. One is simply to do with what people understand this chart to mean.
Note that square brackets are placed around each of these symbols: [ ]. This indicates that the symbol is representing the production/articulation of a given sound and not that it is a linguistic unit or a phoneme belonging to any particular language. In transcribing languages phonemically, one uses (or “borrows”) a small subset of the symbols on the chart to represent distinctive linguistic units in a language. To show the symbols are used as phonemes in a given language and not as phones or allophones, which are representations of the articulation of a sound, we use slash brackets: / /. In training people to use the chart, it has to be understood that producing a phone such as [p] is not going to be the same as, e.g., an English /p/, which is usually aspirated when at the start of a syllable, even though we have used the same symbol. If your phonetics teacher wants to hear a typical English /p/ sound, it will be represented [pʰ] in phonetic transcription.
Another issue is to do with processes for updating or revising the alphabet. There was general rejoicing in the phonetics community when, in 2005, the symbol for the voiced labiodental flap [] was added to the main consonants chart; this was the first revision since 1996. But it is not a matter of someone simply proposing a new sound; evidence must be given for the existence of the sound as a distinctive unit in a given language. More recently, there has been discussion about whether the vowel chart should have a symbol for an unrounded open central vowel as found in German, proposed in Barry and Trouvain (2008), which would be represented with a small capital A [a]. This proposal had in fact been first discussed by the association in 1989 and rejected at that time; Barry and Trouvain (2008) provided a convincing rationale for reconsidering this position, including the fact that there are central vowels at every cardinal tongue height except for in open position, and that there are languages which have this vowel quality in a stable enough way to support representing it on the chart with a single symbol not requiring diacritics (it can, for example, be represented as [ɐ̞], which is the symbol for the most open unrounded central vowel currently on the chart plus the “lowered” diacritic). In December 2011 the matter was finally decided by the IPA council voting against adopting [a] (IPA 2012, p. 245).
Something else the basic alphabet fails to cater for is many of the sounds produced by atypical speakers – that is, people with speech deficits – or children in the developmental stages of sound production. For example, some speakers may produce sounds classified as labioalveolar, which means the speaker’s bottom lip touches the alveolar ridge behind the teeth (amongst typical speakers, the furthest back the bottom lip travels is to meet the upper teeth in labiodental sounds such as [f] and [v]). In order to deal with this, an additional chart known as “the Ext-IPA symbols for disordered speech” was devised, where “Ext” is abbreviated from “extensions” (Duckworth, Allen, Hardcastle & Ball 1990; PRDS Group 1983). This currently exists in its 1997 revision in the IPA handbook (1999, p. 193). For information, labioalveolar sounds are represented by a double-underline diacritic combined with a bilabial or labiodental symbol, so a voiced labioalveolar nasal is [m͇] and a voiceless labioalveolar fricative is [ f͇ ].
And yes, it is possible to describe every sound produced with human vocal apparatus with phonetic terminology. Did you know, for example, that when you “blow a raspberry”, you are performing a voiceless linguolabial trill?  Or that a “gee-up” noise to encourage a horse is a voiceless alveolar lateral click?  Well, now you do.

Is /ə/ "real"?

"Is schwa a real phoneme?" asked a first year student, during a preliminary session preparing them for transcription in the second year. What an excellent question!

The issue arose because I had referred them to John Wells' standard lexical sets to describe English vowel sounds more easily. This is a list of English phonemes with keywords devised by Prof Wells and given in his three-volume book Accents of English (1982). Rather than trying to explain in articulatory terms what /ʊ/ is in comparison with /ʌ/, for example, they can be referred to as the FOOT and STRUT vowels respectively, and then discussion about them appearing (or not) in various accents of English can also be facilitated.

However, mid central unrounded vowel [ə] does not appear in this list ... which leads to the very intelligent question about its "realness".

The schwa vowel is the most commonly occurring vowel in reference accents such as RP or Standard Southern British English (SSBE). In articulatory terms, [ə] is a sound which can be produced by basically relaxing the articulators in the oral cavity and vocalising. From that point of view, it is certainly "real".

From a phonological point of view, however, whether /ə/ is a phoneme or not in English is more tricky. There are no single-syllable citation forms of words containing this vowel, so it is not possible to contrast it with other vowels in minimal pairs, as we would normally expect to do with a vowel phoneme (or any phoneme, for that matter) in order to test its linguistic significance/reality. E.g., we can compare the TRAP and START vowels in British English using minimal pairs such as hat /hæt/ and heart /hɑːt/ and demonstrate that, as the meaning of the word is changed by changing the vowel sound, they are therefore separate linguistic units in English. As it's not possible to do this with /ə/, this is probably why it doesn't appear in Wells' lexical sets.

Schwa is a vowel which only occurs in weak syllables in RP or SSBE and is, therefore, never stressed. This might mean you find it in a bi- or multi-syllabic word such as father /ˈfɑː.ðə/, about /əˈbaʊt/ or conglomeration /kəŋˌɡlɒm.əˈreɪ.ʃən/ (note it is also possible to have syllabic consonants in syllables one and five in the last word) or in something called "weak form words" (here's a nice post on the subject by David Brett).

Weak form words are a small group of one-syllable function words - determiners, prepositions, conjunctions, pronouns, modal and auxiliary verbs, etc. - which have a weak and a strong form. The weak form is the one which is most often used.  It is unstressed, and in many instances the word is realised with /ə/ as the vowel. Common weak form words containing schwa include but, and, the, her, of, can and that (when used as a subordinating conjunction) which are often pronounced /bət/, /ən/, /ðə/, /ə/, /əv/, /kən/ and /ðət/ respectively in connected speech.

The alternation between other vowels (sometimes referred to as "full vowels") and schwa results in the distinctive speech rhythm of English accents such as RP and SSBE; this rhythm is often referred to as "stress-timed" (here's a short definition from the British Council / BBC).

But back to whether schwa is a "real" English vowel or not. One could indeed claim that it is not a phoneme in English, as it merely replaces other vowels when they are realised in weak syllables.  If we compare e.g. economy /ɪˈkɒn.ə.mi/ and economic /ˌiː.kəˈnɒm.ɪk/, we can see that /ə/ is standing in for /ɒ/ in the third syllable in economy and the second syllable in economic. The stress patterns of these words are dependent on other factors - in this case, the suffix -ic causes the main stress in economic to be placed on the syllable prior to it, which is different from economy.

However, as it is such a prevalent vowel in reference accents, and such an important part of the pronunciation of those accents, it tends to be accepted as a vowel phoneme in lists of vowels for those accents.

There are, of course, accents of English which do not use /ə/ very much, if at all - particularly those which are developing in regions of the world where other languages do not use it. Here's an example of a poem in Nigerian English in which the speaker talks about [ðɪ ˈpæʃɒn ɒv ðɪ ˈpoːem] (the passion of the poem) instead of /ðə ˈpæʃən əv ðə ˈpəʊɪm/. If you listen to the poem, you'll hear that he uses very few schwa vowels.



Addendum 28/06/2013: Since posting this, I feel I should just add that the standard lexical sets do indeed include lettER /ˈlet.ə*/ - where * stands for possible linking /r/ - and commA /ˈkɒm.ə/ which cover schwa, and also happY /ˈhæp.i/, covering the weak close front unrounded vowel sometimes referred to as "schwee", but that these do not appear in the list I projected for students from Prof Wells's blog post.  The sets still do not have anything official to represent "schwoo", but what regularly gets used as an example of the weak close back rounded vowel (often rather mid-centralised and not very rounded) is thank yOU /ˈθæŋk ju/ and, as John Cowan suggests below, intO /ɪntu/.

Supper's Ready - let's celebrate!


I was at the Steve Hackett Genesis Revisited II concert in London on Friday, and what a fantastic show it was! Excellent to be transported back to all those Genesis songs I grew up with in the 70s and to see some wonderful guest artists, such as Nik Kershaw and John Wetton. I'm a massive Genesis fan and am not pleased to have been born too late to see them touring with the classic line-up of Banks, Gabriel, Collins, Hackett and Rutherford (so if anyone knows somebody with a TARDIS, let me know).
Steve has Nad Sylvan from Swedish band Unifaun taking on the lion's share of the vocal duties on this tour, and doing a very impressive job.

So why the blog post? My ears picked up one interesting weak vowel difference during the song "Supper's Ready" from the Foxtrot album. In the line "Today's the day to celebrate," Nad sang /ˈseləbreɪt/, whereas on various studio and live recordings Peter Gabriel and Phil Collins sing /ˈselɪbreɪt/. I'm such an anorak.

I wondered how much of this was owing to age differences - I say /ˈseləbreɪt/, for example, and I must be 15 or so years younger than Messrs Gabriel and Collins - or whether it was to do with Mr Sylvan being a non-native speaker of English. I've heard he lived in the US for a period of time, too, so I wondered if it was US pronunciation.

However, whereas the 14th edition of the EPD (1991) gives /ˈselɪbreɪt/ as the only pronunciation of this word, EPD18 (2011) gives /ˈseləbreɪt/ as the first variant for both UK and US English with /ˈselɪbreɪt/ as the second, as does John Wells' Longman Pronunciation Dictionary (LPD), with the Oxford Dictionary of Pronunciation giving their barred [ɪ] symbol in the second syllable to show it is one or the other.

I am deducing, then, with no knowledge of Mr Sylvan's age whatsoever, that this is largely an age difference.

However, it still sounds Australian to me to hear the -ed suffix pronounced with the /ə/ vowel instead of /ɪ/ - for example, started pronounced /ˈstɑːtəd/ rather than /ˈstɑːtɪd/ - although I acknowledge there seems to be a change in favour of /ə/ there, too.

When I was an undergraduate, I wanted to do my dissertation on the pronunciation of English in Abba songs. I was told this was "not academic enough" and ended up doing something on spelling. I'd be positively encouraging any undergraduate student who wanted to look at such things now ...

Nice to see yee!

At Christmas, we had to switch the television subtitles on for my mother-in-law to be able to "hear" the news effectively. On one of our TV sets, we haven't been able to work out how to switch them off again. This was originally a bit of an annoyance but, recently, I've been paying more attention to what's in the subtitles and it's been really interesting.

The thing I wanted to write about here is a phenomenon called GOOSE-fronting, and what prompted it was a subtitler typing the word may instead of now on the BBC Breakfast programme this morning. The presenter, Charlie Stayt - who is on the young side among the presenting team - pronounced the word now as something close to [naɨ] and this was all a bit too confusing for the poor subtitler.  

By the way, I've seen all sorts of other fun incorrect subtitling, including liars for lawyers, which made me laugh out loud - particularly as the lawyers were representing someone to whom the public clearly doesn't give much credibility (mentioning no names). To be fair, news and other live TV shows have to be subtitled very quickly indeed and in real time, so it's not really surprising lexical or grammatical errors get made in these situations. I did actually have an interview many, many moons ago for a BBC subtitling job and I know they are able to watch as well as listen, but sometimes the listening seems to take priority, the subtitler not paying attention to the visuals, and I do sometimes wonder about the general knowledge of some of the people doing it.

Full IPA vowel chart, revised to 2005
(http://www.langsci.ucl.ac.uk/ipa/vowels.html)
As John Wells points out in his phonetic blog post of 16th June 2010, "it was Caroline Henton who first properly documented the new fronting of RP GOOSE, in her 1983 article 'Changes in the vowels of Received Pronunciation', JPhon 11: 353-371". GOOSE-fronting is a process by which the close back rounded vowel /uː/ is produced with a much more front tongue gesture, so instead of old-fashioned RP /uː/, the speaker produced something more like the close central rounded  vowel [ʉː]; this symbol is know as "barred u". You can see this symbol on the full IPA vowel chart reproduced here. This process is also affecting the FOOT vowel, /ʊ/, to some extent ... and this extends to the target for back-closing diphthongs /aʊ/ and /əʊ/.     

More recently, however, the lip-rounding associated with these vowels appears to be in decline among younger speaker groups. Wells mentions this at the end of his blog post, and Cheshire, Gillett, Kerswill and Williams comment on this in their report of 1999; see in particular the Annexes from p. 16 onwards.  As an observation, the younger speakers of (near-)RP accents get, the more fronted and unrounded their GOOSE and FOOT vowels seem to be. There is very little difference for some speakers between GOOSE and geese, for example, and between mouse and mice. Natasha Kaplinsky, another erstwhile rather younger BBC Breakfast presenter, commented to one interviewee that it was [ˈnaɪs tə ˈsiː jɨ] ("Nice to see you"), for example.

This is not something only observed in (near-)RP but also in other accents. It has been noted as a phenomenon in South African, Australian and New Zealand English, and we even note that it has been recorded in Hong Kong English, too (Setter, Wong & Chan 2010), which may be more interesting as, in learner terms, it has traditionally been based on a conservative RP accent.

John Wells comments in his blog post that, nearly a century ago, Daniel Jones had spotted GOOSE-fronting in the environment of a preceding /j/ - so in, e.g., music or beauty, but not in spoon  - and that it could be spreading from there. Wells does not attempt to explain the unrounding of the lips, however. I'm not too hung up on the "whys" of this, and just enjoy observing the differences and, sometimes, the confusion which results.

Fun and games with /r/

Well it's now January 2013 and I haven't posted anything since September 2012.  The good news is that my module "English in the World" starts again this term - tomorrow, in fact - so I should have more to say.

In the mean time, I thought you might enjoy my retelling of a conversation I had with a friend about intrusive and linking /r/.  She was complaining that someone on the television had pronounced the word "drawing" as /ˈdrɔːrɪŋ/.  This is in fact the way I pronounce it (which doesn't mean it's necessarily right, I should hasten to add!).  The Cambridge English Pronouncing Dictionary gives /ˈdrɔː.ɪŋ/ as the "-ing" form of "draw" but notes in a box below that an intrusive /r/ is sometimes inserted.

My friend was horrified by this.  "It sounds terrible!" she wailed. We then had a discussion about value judgments and language but she wasn't convinced.

In fact, intrusive /r/ is an interesting one.  If you are a speaker of a rhotic accent - i.e., one in which you always pronounce "r" everywhere it appears in the spelling (e.g., General American; Irish; Scots) - then intrusive /r/ is just not something you do.  It's not there so you don't say it (although I note the box about "drawing" seemed to suggest that it even occurs in American English accents - would anyone like to comment?).

Intrusive /r/ comes about in non-rhotic accents by analogy with linking /r/.  Non-rhotic accents are those in which the speaker only pronounces /r/ if it is followed by a vowel (e.g., RP; Australian).  Linking /r/ is an optional connected speech process which happens in non-rhotic accents, such as RP, in rapid speech where there is an "r" in the spelling and the following word begins with a vowel.

E.g.:

  1. In "My car burns too much fuel these days", we do not pronounce the /r/ at the end of "car" in non-rhotic accents as the next word begins with a consonant - /maɪ ˈkɑː bɜːnz ˈtuː mʌtʃ ˈfjʊəl ðiːz deɪz/;
  2. In "My car always starts on cold mornings", we may very well pronounce the /r/ at the end of "car" as the following word begins with a vowel - /maɪ ˈkɑːr ɔːlweɪz ˈstɑːts ɒn kəʊld ˈmɔːnɪŋz/ (I've not added in any assimilation here but you might get them at the end of "on" and "cold") - but we wouldn't pronounce the "r" in "start" as it is followed by a consonant.
It is not necessary to perform linking /r/ in 2., but most speakers of e.g. RP will do it.

So, why does intrusive /r/ happen - i.e., why would a speaker pronounce "drawing" as /ˈdrɔːrɪŋ/ when there is evidently no /r/ at the end of "draw"?

If you consider the words which can contain a linking /r/, these all have vowels in the non-high area of the vowel chart, all of which are spelled with "r" at the end of them.  See HERE for the IPA vowel chart and compare the position of the vowels (note these are English phonemes listed below and not Cardinal Vowels).  The vowels are as follows:
  • /ɑː/ - e.g., "car"
  • /ɜː/ - e.g., "cur"
  • /ɔː/ - e.g., "core"
  • /ɪə/ - e.g., "pier"
  • /eə/ - e.g., "pear"
  • /ʊə/ - e.g., "pure"
  • /ə/ - e.g., "mother" /ˈmʌðə/
In the case of /ɪə/, /eə/ and /ʊə/, these vowels are referred to as "centring" diphthongs as the tongue moves from the first vowel towards the second vowel which is a central one, /ə/.   NB. /ʊə/ is becoming rather low-frequency in modern RP and is often replaced with /ɔː/.

This doesn't mean you have to have an "r" in the spelling to have these vowels in a word, however, and this is where intrusive /r/ comes in.  For example:
  • In "I can see the pier over there", an RP speaker will most likely have a linking /r/ at the end of "pier" because the next word begins with a vowel - /ˈaɪ kən siː ðə ˈpɪər əʊvə ˈðeə/ (Quiz: There is no /r/ at the end of "over" and "there" - why not?)
  • In "The mere idea of it!", there is likely to be a linking /r/ at the end of "mere" but ALSO an intrusive /r/ at the end of "idea" - /ðə ˈmɪər aɪˈdɪər əv ɪt/ - because it contains one of the set of vowels in the list above.  This will sound very odd indeed to a speaker of a rhotic variety.
One must note, however, that linking and intrusive /r/ are both optional connected speech processes; they do not HAVE to happen.  For reasons of fluency, they often do.  My friend was saying that she would always put a glottal stop between "idea" and "of" in that last example; if I could hide behind her with a recording device to find out whether this is true in such instances, I would ... but of course this would be unethical.

In the Lingua Franca Core, Jenny Jenkins recommends always pronouncing "r" where it is found in the spelling, i.e., adopting a rhotic accent.  Personally, I can't think of many occasions in which my r-lessness or insertion of linking or intrusive /r/ has been a problem.  However, it's quite possible that I wouldn't have as, often being considered a role model for my particular accent, it is unlikely that I would ever have been challenged.
