Phonetics and Phonology FF1B Lecture 5 THE SYLLABLE · In the flow of speech, it is the utterance which is the largest unit constituted by the speaker. An utterance can be divided into sentences or clauses which are relatively independent as to their meaning and form. · The word is an independent unit only in the sense that its meaning can be identified within a given context. · The syllable is the basic rhythmical phonic unit. Phonologically it is the basic unit at the prosodic level, ie it is the bearer of prosodic, suprasegmental features such as stress, quantity, tone and rhythm. There are many theories covering the nature and the structure of the syllable, we will be concerned with the way Roach presents it in his book. The nature of the syllable: - from a phonetic point of view, syllables are usually described as consisting of a centre which has little or no obstruction to airflow and which sounds comparatively loud; before and after the centre, there will be greater obstruction to airflow and/or less loud sound. - syllables are basically carried by obligatory vowels which can be preceded and followed by optional consonants. example 1: err /ɜ:/ example 2: fur / fɜ:/ example 3: furs /fɜ:z/ Basic structure of the syllable: - the obligatory vowel within the syllable structure = peak (centre) - the optional consonant(s) that can precede the peak = onset - the optional consonant(s) that can follow the peak = coda SYLLABLE : (onset) - peak - (coda) The structure of the ONSET - the maximum number of consonants within the onset is three: o the first consonant in the onset is called pre-initial; if present it is always represented by /s/; o the second consonant in the onset is called initial; this can basically be any English consonant, especially if the onset only consists of this initial consonant; o the third consonant in the onset is called post-initial; this is exclusively represented by /l/, /r/, /w/ and /j/; ONSET: (pre-initial) - (initial) - (post-initial) o the onset without consonant is called zero onset; o obviously, some combinations are preferable, some combinations of consonants are impossible in English: *sʒw *mr *hl (NB: /ʃw/ is only present in the vowel name ‘schwa’ and the brandname of the soft drinks, Schweppes: /ʃwʌ/ , /ʃweps/.) The structure of the CODA: o the maximum number of the consonants within the coda part is four; o the individual ‘slots’ bear the following names: pre-final consonants (only a small set: /m/, /n/, /ŋ/, /l/, /s/); final consonants (basically any English consonant – but combinations within consonant clusters are limited); post-final consonants – again a small set /s/, /z/, /t/, /d/, /θ/. More examples: 6. fifths /fІfθ/ - 2 post-final consonants 7. next /nekst/ - 2 post-final consonants 8. twelfths /twelfθs/ - 2 post-final consonants 9. sixths /sІkθs/ - 3 post-final consonants 10. texts /teksts/ - 3 post-final consonants !!! NOTE: if the peak (centre) of the syllable is not carried by a vowel we need to consider a syllabic consonant /l/, /m/, /n/, /ŋ/, /r/, eg. middle /mІdl̩/ SUMMARY This is the maximum phonological structure of the syllable: pre- initial post- vowel pre- final post- post- post- initial initial final final 1 final 2 final 3 ONSET PEAK CODA ---------------------------------------------------------------------------------------------- REDUCTION = strong and weak syllables § Reduction is basically a sort of vowel weakening in unstressed syllables, eg. bigger /bІgə/, perhaps /pəˈhaeps/. § This change is in quality, or sometimes – but not necessarilly - connected with the change in quantity. § Quality = a distinction between strong and weak vowels § Quantity = a change in length (ie short and long vowels) Czech does not know this process of reduction of strong vowels in unstressed syllables, however it is one of the key features of the sounds of English! As you know, syllables are carried by vowels or syllabic consonants. The vowels in those syllables can be strong or weak, depending on stress. Which are the weak vowels? 1. ə (‘schwa’) 2. i (ie a close front unrounded vowel in the general area of /i:/ and /І/) 3. u ( ie a close back rounded vowel in the general area of /u:/ and /ʊ/) Strong vowels are any other vowels except /ə/, /i/ and /u/. STRONG AND WEAK SYLLABLES § Rule 1: stressed syllables MUST always be strong UNDER ANY CIRCUMSTANCES (containing strong vowels), eg. attend /əˈtend/ , particular /pəˈtІkjələ/ § Rule 2: unstressed syllables are MOSTLY weak but occasionally also strong, eg. furniture /ˈf3:nІtʃə/ , access /ˈaekses/- not */ˈaeksəs/, superstar - /ˈsu:pəstɑ:/ not */ˈsu:pəstə/ § The most widespread weak vowel in English is schwa /ə/. § However in longer words, there is often a kind of oscillation between /ə / and /i/, or /ə / and /u/. § Example 1: modality /məʊˈdaeləti/ or /məʊˈdaeliti/ § Example 2: particular /pəˈtІkjələ/ or /pəˈtІkjulə/ ---------------------------------------------------------------------------------------------- WEAK FORMS x STRONG FORMS - weak form is a word in English which can be pronounced in two ways, strongly and weakly but the weak pronunciation is preferred. !!! weak syllable ≠ weak form !!! - weak syllables occur in lexical words but weak forms are words themselves, often grammatical words like prepositions, auxiliary verbs, articles, etc. - the complete set of weak forms is a closed group of about 40 items (of which Roach gives 28) – please see one of the handouts for your seminar or the copy I gave some of the groups last semester. The use of strong forms The words from the above mentioned ‘list’, which have weak forms also have strong forms, which MUST be used in the following cases: 1. Whenever the word is stressed, as it may be: ˈkaen aІ ?, ˈdu: d-eІ ?, ˈhaev ju ?, ˈhi: ˈlaІks ˈh3: bət dəz ˈʃi: ˈlaІk ˈhІm ? 2. Whenever the word is final in the group: ˈpi:t haez, aІ ˈdəʊnt ˈni:d tu: , ˈju: ɑ:, ˈhu:z Іt frɒm? 3. Exceptions: he, him, his, her, them, us have their weak forms even in final positions (unless they are stressed) not has its weak form finally when attached to can, have, is, etc.: ˈdʒɒn ˈkɑ:nt, ʃi: ˈІznt ; but never otherwise: aІ ˈhəʊp nɒt. ---------------------------------------------------------------------------------------------- EXERC ISES see Roach (1995: p.84)
