Phonology:Streamlined phonetic transcription LING 400 Jan. 19, 2010 Prof. Hargus
Overview • Broad vs. narrow phonetic transcription • Predicting phonetic detail • Phonology turn cell phones off please
Broad vs. narrow transcription • Phonetic transcription can have more or less detail • Aspiration in English • Relatively more detail: narrow transcription • e.g. [phɑɪ] pie • Relatively less detail: broad transcription • e.g. [pɑɪ] pie • When should [h] be included in a transcription of English?
Phonetics of aspiration • pie always pronounced with aspiration • puff of air test • Why then would aspiration never be transcribed?????????????????????
Predictable vs. unpredictable information • Languages contain • Unpredictable information • list • represented in dictionary • Words I know: pie, spy, sip, crappy, etc. • Vowels of my language: [i], [ɪ], [eɪ], [ɛ], etc. • Predictable information • X Y/ A __ B • represented in grammar • “non-low back vowels are (usually) round” • [p] [ph] / (to be specified)
Voiceless labial stops in English • Words that contain voiceless labial stop • at beginning of a word: • pie, pry, play, pew • after [s]: • spy, spry, splay, spew • at end of word: • sip, rap, crap • in middle of word • following vowel stressed: support, U-Pick • following vowel unstressed: happy
[p] and [ph] • Abbreviations ___ = location of vowel or consonant # = edge of word V = vowel |= stress • [p] occurs in places where [ph] does not
Distribution of voiceless labial stops in English All the places voiceless labial stops can occur in English #__l #__ Vs__ V|__V__# V__V • [p] and [ph] never occur in “the same place” • [p] and [ph] are “in complementary distribution” etc.
Predicting aspiration • [ph] found in two places • #__ • V |__V • [p] is aspirated when word-initial or before a stressed vowel. • Aspiration is predictable in English
Broad vs. narrow transcription • Broad transcription represents only unpredictable information • Transcriptions of pie • broad: [pɑɪ] • narrow: [phɑɪ] • (In real life, transcriptions are usually as broad as possible.)
Phonology • More abstract phonetics • Part of grammar that makes explicit rules for pronunciation • Aspiration is a rule of English (not all languages) • Spanish tono ‘tone’, dono ‘I donate’ • Transcriptions of pie • narrow: [phɑɪ] • broad: [pɑɪ] or /pɑɪ/
Levels of representation • Phonetic representation [phɑɪ] • directly observable • measurable properties • [ ] brackets, contains (allo)phones • Phonemic representation /pɑɪ/ • inferred, not observed • abstract, streamlined representation • / / brackets, contains phonemes Aspiration (phonological rule)
Inferring the phonemic representation • How? • Minimal pairs/sets • sounds in contrast • Complementary distribution • sounds not in contrast
Minimal pair • Two words differing in meaning and only one phonetic property • A minimal pair for voicing in English • [|kɹæbi] crabby vs. [|kɹæpi] crappy • therefore, /p b/ in English • Phonetic difference between pair not due to context • Minimal pairs contain phonemes • /|kɹæbi/, /|kɹæpi/ • A minimal set • /hid/, /hɪd/, /heɪd/, /hɛd/, /hæd/
Complementary distribution of sounds • Predictable aspects of pronunciation can be due to • Influence of neighboring sound • Position within word
Another phonological rule of English Rounded [ɹw] and unrounded [ɹ] are in complementary distribution. Decide which of these sounds is the phoneme and describe the distribution of the other in a phonological rule.
Distribution of sounds Start by noting preceding and following sound or position. (‘#’ = edge of word.) Then generalize. [ɹw] always precedes a vowel; [ɹ] always precedes consonant or word edge.
From distribution to rule • “[ɹw] always precedes a vowel; [ɹ] always precedes consonant or word edge.” • Sound derived by rule occurs in more specific context • “vowel” more specific than “consonant or word edge” • [ɹw] therefore derived by rule • /ɹ/ [ɹw] / ___ V • phoneme occurs in more general context
Summary • Different levels of detail can be shown in phonetic transcription • Predictable phonetic information part of rule system, usually left out of phonetic transcription • primary evidence for rule system: complementary distribution of sounds • Unpredictable phonetic information • primary evidence: minimal pairs or sets
