Phonemes and Allophones of English Consonants

Phonemes and Allophones of English Consonants

Rough definition of

Press 1997) and • “The smallest distinct sound unit in a given : e.. /»tIp/ in English realizes the Effects related to aspiration and three successive phonemes, represented in ‘devoiced’ voiced sounds and a few by the letters t, i, and p. other issues

Phonemic differences vs. Phonemes allophonic differences • Strict, detailed definitions of the term phoneme are • Differences in speech sound that can signal complex differences between two different are – Not part of this course phonemic differences – Take courses to fight over the details • Other differences in speech sound that are • Rough and ready idea is indispensable for practical clearly audible are only allophonic – Must make a distinction between phonemic and differences allophonic differences – ‘pronunciation variants’ that cannot signal different words. Representing allophonic Answer: ‘pie, spy, buy’ differences • ‘Broad’ (= coarse-grained) transcription enough Phonemes in ‘/’ ( or solidus, pl solidi) for phonemic representation marks – Choose simple symbol for a ‘representative’ (allo) /p/ /b/ • ‘Narrow’ (= fine-grained) transcription often requires diacritics • Diacritics for stops [p] [pH] [b] [b8] pH - aspirated p p| - ‘p with inaudible release’ (‘unreleased p’) b8 - ‘(partially) devoiced b’ Phones in square brackets

Examples ‘Stop.’, ‘Stop!’, Examples: ‘pie, spy, buy’ ‘Stop!!’, ‘Stob!’ • ‘pie’ [»pHaj] • ‘Stop.’ [»stAp|] • spy [»spaj] • ‘Stop!’ [»stAp] • ‘buy’ [»b8aj] or [»baj] • ‘Stop!!’ [»stapH] • Which of [b8] [pH] [p] are allophones of the • ‘Stob!’ [»stab] or [»stAb8] same phoneme? • Which of [b] [pH] [p] are allophones of the same phoneme? Answer: ‘Stop(!!!) Stob.’ Example rule

Rough notation Translation

Conditioned allophone: The phoneme /X/ is • The phoneme /p/ is realized as an aspirated p (the realized as phone [y] in environment phone [pH]) at the beginning of a word or between between A and B a weak vowel and a stressed vowel. /X/ --> [y] / [A] _ [B] • It is realized optionally as an unreleased (inaudibly released) p ( the phone [p|] word finally Allophone in • It is realized as an ordinary voiceless (un- or /X/ --> [y] or [] (optionally) weakly- aspirated) stop after /s/ and elsewhere. Allophones of stops: Aspiration Allophone rule sheet to follow and release • We will examine some important • Consider the following words allophones in English Cs and Vs • ‘tip’, ‘pit’, ‘spit’, ‘plum’, ‘queen’, ‘apt’ – Then I’ll handout rule summary (and post on • Broad and Narrow transcriptions web) • ‘Line drawings’ showing relative timings of • For details see Chapter 3 of Rogers and constrictions at articulators Appendix F (p 292 - 298) – (See Rogers p 25-27 for overview) – Our rules will be much shorter

Devoiced ‘d’ and unaspirated ‘t’ may often be perceptually equivalent [d]8 vs. [t] ? Any real difference Side effects

• ‘Devoiced’ obstruents can be very similar to • So far we’ve looked mainly at allophones of voiceless unaspirated sounds with respect to voiced and voiceless obstruents themselves ‘actual’ voicing – Some special things happen to things next to • Small differences may remain in obstruents ‘excitation’ from larynx • e.g. vowels are shorter before voiceless obstruents – Other ‘secondary features’ of ‘devoiced voiced’ • Next: Effects on approximants next to sounds resemble ordinary voiced sounds aspirated obstruents • so they may sometimes be perceptually separable

• Unreleased (inaudible release) stops often occur in stop • N.A. English /®/ is pretty strongly rounded clusters – Rogers p 60. – ‘apt’, ‘act’, ‘abdicate’ – Could* be transcribed most accurately [”W] – [»Qp|tH] [»Qk|tH] [»Qb|dI«kHejt|] • /S, Z, tS , dZ/ are also somewhat rounded • Unreleased stops often occur prepausally (e.g. utterance (compared to /s, z/) final) – These could* be transcribed / SW, ZW, tSW , dZW / – Even possible for word like [»Qk|t|] making final stop very *But we won’t bother in ‘moderately narrow transcription’ difficult to hear. ??? What would we do with ‘Schreck’, ‘Schwepps’ vs. • Many do not allow inaudible releases of stops ‘she’ – Require aspiration or brief vocalic release • Compare: [»Qk|tH] [»QkHtH] [»Qk´tH]

Special releases (plosions) Some additional details Nasal and lateral releases • Stops before homorganic nasals (mainly d+n) often result in a ‘nasal release’ • Most of the things so far might show up on or ‘nasal plosion’ (Rogers p 57) a quiz for ‘moderately narrow’ transcription – Can be transcribed with d + raised n • ‘Rodney’ [ »®Adnni] • ‘kindness’ [ »kHajndnn´s] • Similarly, ‘d’ before ‘l’ may lead to ‘lateral release’ or ‘lateral plosion’ • Some additional details will not show up in – Can be transcribed as d + raised l – ‘sadly’ [ »sQdlli] any live transcription quiz ever • What about ‘butler’??? - Some facts discussed might be addressed in [»b" /tll´®] emphatic [»b" tl•´®] multiple choice or short answer questions
