1 Ling 240 Phonetics & Phonology

2 Agenda Articulatory processes: Sounds are pronounced differently in different environments Using diacritics to represent other features of phones (narrow transcription) phones vs. phonemes

3 English [p] vs. Spanish [p] English Spanish pin [p h ] poco [p] pool [p h ] peso [p] pace [p h ] papa [p] pill [p h ]

4 English [t] vs. Spanish [t] English Spanish tool [t h ] todo [t] tea [t h ] te [t]

5 Aspiration Aspiration: release of air OR Period of voicelessness after release of the stop (before the following vowel)

6 Aspiration

7 Aspiration pin spin tip

8 Aspiration tall stall bit note notation attack

9 Aspiration

10 Aspiration [p], [t], [k]

12 (Narrow) Transcription time tree pot stop water button

13 Did you transcribe them like this? time tree pot stop water button [tåim] [tri] [påt] [ståp] [wåt\r] [b t\n]

14 The t is pronounced differently in each word time tree pot stop water button [t h åim] [tßri] [p h åt ] [ståp] [wå \r] [b\ \n]

15 The t is pronounced differently in each word time tree pot stop water button [t h åim] [tßri] [p h åt ] [ståp] [wå \r] [b\ \n] aspirated palatalized unreleased unaspirated flap (voiced) glottal stop

16 Why are they all spelled with a t?

17 How do we store the pronunciations of water and button? [wå \r] or [wåt\r] [b\ \n] [b\t\n]

18 Hypothesis A: [wå \r] must be stored as a special pronunciation of water Hypothesis B: the pronunciation of t as [ ] is derived by a rule

19 Is the pronunciation predictable? [t h ] [ ] [ ] time top table water little butter notable button kitten carton

20 Is the pronunciation predictable? [t h ] [ ] [ ] time top table (cf. notation) water little butter notable button kitten carton

21 Patterns [t h ] occurs at the beginning of stressed syllables. [ ] occurs between two vowels [ ] occurs in the middle of words before a syllabic nasal.

22 Articulatory Processes Sounds are pronounced differently in different environments These are RULES in mental grammar

23 Different pronunciations of /t/ in English [t h ] [t] /t/ [ ] [ ]

24 Rules the sound /t/ changes to [ ] before a syllabic nasal /t/ _ [ ] / _ \n

25 Rules the sound /t/ changes to [ ] between two vowels /t/ _ [ ] / V _ V

26 Rules the sound /t/ changes to [ ] between two vowels NOTE: these are NOT rules about spelling

27 In what sense are these all the same sound?? [t h ] [t] /t/ [ ] [ ]

28 The way words are stored in the Mental Lexicon time tree pot stop water button /tåim/ /tri/ /påt/ /ståp/ /wåt\r/ /b t\n/

29 Lexicon /wåt\r/ Rules /t/ -> [ ] / V_ V Output [wå \r]

30 Lexicon /wåt\r/ Rules /t/ -> [ ] / V_ V Output [wå \r] Phonemes Allophones

31 Phoneme the abstract representation of a sound. the way the sound is stored in word in the mental lexicon

32 Allophone how the sound is actually produced in a given environment an instance of a phoneme a member of a more general category

33 Articulatory Processes Sounds are pronounced differently in different environments These are RULES in mental grammar

34 environment = the phonological context of a sound position in the word neighboring sounds

35 Articulatory Processes are RULES Not just automatic reflexes of the vocal tract How do we know?

36 Articulatory Processes are RULES Not just automatic reflexes of the vocal tract How do we know? Evidence: Different processes in different languages e.g., cotton is not pronounced with [ ] in some dialects

37 Summarizing so far There are RULES in mental grammar that determine the pronunciations of sounds

38 What is stored: Building a Grammar What we hear: Lexicon Output /tåim/ /tri/ /påt/ /ståp/ /wåt\r/ /b t\n/ RULES [t h åim] [tßri] [p h åt ] [ståp] [wå \r] [b\ \n]

39 Different pronunciations of /t/ in English [t h ] [t] /t/ [ ] Allophones Phoneme [ ]

40 Inventory of Phonemes Are [p] and [b] different phonemes in English? Two steps in finding out the phonemic status of sounds

41 Inventory of Phonemes First step: look for minimal pairs if difference between sounds causes a difference in meaning => contrastive => different phonemes

42 Inventory of Phonemes Are [p] and [b] different phonemes in English? pin vs. bin tap vs. tab [pin] vs. [bin] [tæp] vs. [tæb] Conclusion: /p/ and /b/ are separate phonemes

43 In contrast [st h åp] [ståp]... no difference in meaning [t h ] and [t] are allophones of /t/

44 Inventory of Phonemes Second step: If no minimal pairs, look for a pattern (distribution of the two sounds) What environments does sound X occur in? What environments does sound Y occur in?

45 Exercise: making generalizations about the environments can /k(æ)n/ I can ask I can see I can bake I can play I can go I can gather [åi kn æsk] [åi kn si] [åi km beik] [åi km plei] [åi k go ] [åi k gæ \ ]

46 Generalizations [m] occurs before a bilabial consonant [ ] occurs before a velar consonant [n] occurs everywhere else (elsewhere)

47 Generalizations => Rules /n/ becomes [m] before a bilabial consonant /n/ becomes [ ] before a velar consonant elsewhere /n/ is pronounced [n]

48 But don t [m] and [n] belong to separate phonemes in English?

49 [m] and [n] /n/ /m/ [n] [m] [ ] [m]

50 Now apply the same process to determine the grammars of other languages
