  1. Phonology Organization and interaction of sounds in a language sound system

  2. Phonology • Up to this point we have studied the individual speech sounds of English • Now we will learn some basic ways that the sounds of English interactsystematically • This will help us comprehend the concept of a sound system

  3. Phonology • Each language has its own sound system: the specific processes that occur as sounds interact during speech

  4. Phonemes • Compare the following words bit – pit tool – toll bag – bang What do we notice about each pair?

  5. *Minimal pairs Definition: Words that differ in one sound only • The fact of different meanings of the words proves that the sounds are recognized psychologically as ‘different sounds’ I.e., they are distinct from each other

  6. Minimal pairs • It is the existence of minimal pairs that demonstrates phonemes.

  7. *Phoneme defined • a sound that native speakers recognize as a distinct language sound and which makes a difference in meaning (the sound has a distinct value in the speech system)

  8. Phonemes • Thus, a phoneme is not the mere fact of a speech sound, but something recognized psychologically

  9. Phonology • In actual speech, pronunciation of speech sounds may vary from speaker to speaker, word to word, time to time • This variation is systematic and conventional

  10. *Variation in phonemes Six variants of phoneme /t/ • too [thu] aspirated

  11. Variants of /t/ • stew unaspirated (plain)

  12. Variants of /t/ • lot [latך] unreleased

  13. Variants of /t/ • butter flap /ſ/(see p. 46 for symbol)

  14. Variants of /t/ • button [‘bə?ən] glottal stop

  15. Variants of /t/ • hunter [hənər] t-sounddeleted

  16. Variants of /t/ • tea aspirated • stay unaspirated (plain) • potunreleased • better flap • batman glottal stop • winter deleted

  17. Variation in phonemes • These different pronunciations do not make a difference in meaning (i.e., they have the same value, /t/) • These different pronunciations are all recognized by native speakers as /t/ • The variation is conventional — the same among speakers in a community

  18. *Allophone • One of the different pronunciations of a speech sound that is still recognized as having the same value (value of the phoneme), and thus makes no differencein meaning I.e., all the above sound like /t/ to us • Each variant constitutes an allophone

  19. Phonemes • The concept of a phoneme is language specific

  20. Phonemes In English both • aspirated thtoo [thu] and • unaspirated t stew [stu] still are felt as /t/ (variants of English /t/) i.e., [t] and [th] are allophones of /t/)

  21. Phonemes But Chinese distinguishes aspirated and unaspirated sounds, 套 thao ‘set’ 道 tao ‘the religion’ /th/ and /t/ are distinct: They are different phonemes in Chinese

  22. Observations of variation • Observations like these result in *descriptive rules about a language • Here rule means dynamic principle

  23. *Derived rules The following rules can be derived for the allophones of English /t/ • At beginning of syllable, Voiceless stops are aspirated — too; pie; can [*Aspiration rule]

  24. Rules for allophones of English /t/ 2. *After /s/, Voiceless stops are plain — • spy, stay, ski

  25. Rules for allophones of English /t/ 3. *At the end of syllables and words, Voiceless stops are often unreleased in rapid speech — • bought; hit; what

  26. Rules for allophones of English /t/ • 4. *Beforenasal sounds /t/ may become glottal stop — button; waitin’; huntin’

  27. Rules for allophones of English /t/ • 5. (American Eng.) *Between vowels (after stressed syllable) Voiceless alveolar stops become voiced flaps — butter, better, water

  28. Rules for allophones of English /t/ • 6. *Aftera nasal sound, /t/, may be deleted — hunter [hənØr], winter [wInØr] (but also sandwich, grandma for some)

  29. Some allophones in Japanese • Japanese /t/ has the following allophones of /t/ in syllables: ta, te, to, tsu, chi Rules?

  30. Some allophones in Japanese • Before /a/, /e/, and /o/, /t/ is [th] • Before /u/, /t/ is [ts] • Before /i/, /t/ is [t∫] This allophonic variation occurs in all words

  31. *SYSTEMATIC VARIATION • These observations — SYSTEMATIC VARIATIONS — can be called Phonological processes or Phonological rules

  32. More phonological processes *Assimilation – Sometimes variation caused by influence of sounds that come after it in speech string— • San Bernardino – Sa[m]Bernardino- /n/ labialized by influence of following /b/; • tenth- /n/ dentalized by following interdental

  33. More Assimilation • Or on sounds that precede it: barn- /n/ retroflex twelfth_night- /n/ dentalized

  34. Assimilation • *Defined: The process of a sound changing in some way to be more like sounds that precede or follow it

  35. Assimilation in Korean • Korean /hap/ but [hamnida], — the /p/ is nasalized before /n/

  36. Phonological processes • *Palatalization: Because of the influence or a neighboring sound, the place of articulation shifts to the palate • Did you eat → • What are you doing → • “I need your vote” →

  37. Palatalization in Japanese • (Jp.) teyuuka ‘anyway’ → t∫uuka • ( Recall, in Japanese /t/ before /i/ → t∫)

  38. Phonological processes • *Devoicing please true cream • The aspiration of the voiceless stop causes devoicing of the following /r/ or /l/

  39. Phonological processes • *Stop insertion sen~se once hamster angst [voiceless stop] inserted between nasal sound and /s/ at same point of articulation

  40. Phonological processes *Metathesis inversion of consonants: • ask ~ aks • cavalry ~ calvary • comfortable ~ [kəmftərbl]

  41. Phonological processes • *Plural Voicing/Devoicing Beds – [-z] Watches – [-әz] Hats – [-s] English Rules?

  42. *Plural Devoicing • Rules – Beds – [-z] after voiced final sound Watches – [-әz] after sibilants Hats – [-s] all the rest, i.e., voiceless sounds

  43. Phonological processes • Each language has its own phonological processes

  44. Phonological processes • In English – shoes – [∫u-z] plural • Where in Spanish – los amigos – [-s]

  45. Phonological processes • Phonological processes are systematic They operate throughout the vocabulary and speech stream, according to principles (rules) which can be induced

  46. Phonological processes • The processes are conditioned by the features of sounds surrounding the sound in question E.g. • /t/ followed by /i/ → palatalization • /n/ followed by /b/ → labialization • Form of Pl (-s) agrees determined by last sound of word stem: shoes, judges, hats

  47. Phonology • *These examples of allophones, • the systematic variation they show and • the phonological processes (or rules) derived from them show that: • Speech sounds in a language interact systematically • Their interaction is based on observable principles

  48. Phonology This interaction is the subject of the study of phonology
