3. Housekeeping Morphology homeworks are due! Also: I will be gone next week… Danica will be taking over the reins.

4. Allomorphy What’s going on here? /in-/ + probable=improbable /in-/ + mobile=immobile /in-/ + possible=impossible /in-/ changes to /im-/ before both /p/ and /m/. /p/ and /m/ are both produced with the lips.  To explain patterns like this, we’re going to need to know something about how we actually produce the sounds of English.  We have to study Phonetics!

5. What is phonetics? Phonetics is the scientific study of speech sounds. It consists of three main sub-fields:  Articulatory phonetics  = how speech sounds are produced  Acoustic phonetics  = how speech sounds are transmitted from producer to perceiver  Perceptual phonetics  = how speech sounds are perceived

6. Phonetic Transcription  The primary tool of phonetic science is phonetic transcription.  The basic idea:  represent speech as a sequence of segments.  i.e., with an alphabet.  Segments = individual consonants and vowels.  Deep thought questions:  What kind of alphabet should we use?  How about the English alphabet?

7. The Trouble with English Some letters represent more than one different sound c:recallvs.receiveg: gear vs. siege Some letters represent no sounds at all receiveusehighknee Sometimes two letters represent just one sound recallphonetics Some letters represent two or more sounds at once taxuse The same sound can be represented by many different letters (or letter combinations). sh:shy, mission, machine, special, caution

8. Phonetic Alphabet Solution: use a phonetic alphabet In a phonetic alphabet, sounds and symbols have a one- to-one relationship to each other Each symbol represents one sound Each sound is represented by one symbol The use of a phonetic alphabet to represent speech is called phonetic transcription. Our phonetic alphabet of choice: The International Phonetic Alphabet (IPA).

9. The IPA  Presided over by the International Phonetic Association  Created in 1886  Still active and evolving today.

10. IPA Principles 1. The use of a symbol in a transcription is essentially a claim that the speaker produced a certain combination of articulatory gestures. 2. “There should be a separate letter for each distinctive sound; that is, for each sound which, being used instead of another, in the same language, can change the meaning of the word.” one letter  one sound Sound contrasts can be shown to exist in a language by finding minimal pairs.

11. Minimal Pairs A minimal pair consists of: two words that have different meanings which differ from each other in only one sound. Some minimal pairs in English: pit vs. bit~ /p/ vs. /b/ beet vs. bead ~ /t/ vs. /d/ boat vs. boot~ /o/ vs. /u/ A series of minimal pairs is called a minimal set. tee ~ bee ~ key ~ sea ~ fee …

12. More IPA Principles 3. The alphabet should consist as much as possible of the ordinary letters of the Roman alphabet. 4. In assigning values to the Roman letters, international usage should decide. ex: vowel in English “bee” is transcribed with [i] 5. When any sound is found in several languages, the same sign should be used in all. This applies to very similar shades of sound. ex: French [u] = English [u] = Korean [u]

13. Caveats  The IPA is not perfect.  It is a useful tool for representing speech as a sequence of segments.  Phonetic transcription is an inexact science.  Impressionistic  “I think the speaker said this”  Important: speech perception is molded by your native language background.  Production, too!   Mechanical analysis can come in handy

14. Phonetic Reality  Here is an acoustic waveform of a sample of speech: Where were you a year ago?  In the physical world, speech lacks the discreteness and strict sequentiality of alphabetic representations.   Phonetic transcriptions of speech are always abstract

15. The Problem of Abstractness  How abstract should a phonetic transcription be?  The IPA solution: only capture contrastive differences between sounds.  Contrast:bit vs. pit  Non-contrast: vs. How about “Don” and “Dawn”? Here’s the catch: The IPA must be able to represent all the contrasts between sounds that are found in language. …including some which we cannot easily hear.

16. Technical Terms A phone is any sound that is used in speech. (may or may not be contrastive) A phoneme is a contrastive sound in a language It may be used to distinguish between words in minimal pairs. An allophone is a phonetic variant of a phoneme Different allophones often occur in specific contexts. Note: analogy with allomorphs.

17. Phonemic Analysis Phoneme: /t/ Allophone 5: ‘bit’ (aspirated) (unaspirated) “flap” “glottal stop” (unreleased) In our native language, we tend to hear the phonemes that the allophones belong to… Rather than the allophones themselves.

18. Broad and Narrow  Broad transcriptions Represent only contrastive sounds (phonemes) Enclosed in slashes: / / Generally use only alphabetic symbols Narrow transcriptions Represent phones Capture as much phonetic detail as possible Enclosed in brackets: [ ] Can require use of diacritics

19. English Phonemes 1.[p] ‘pot’7. [r] ‘rot’12. [m] ‘ma’ 2.[b] ‘bought’8. [f] ‘fought’13. [n] ‘not’ 3.[t] ‘tot’9. [v] ‘vote’14. [l] ‘lot’ 4.[d] ‘dot’10. [s] ‘sot’15. [w] ‘walk’ 5.[k] ‘kit’11. [z] ‘zit’16. [h] ‘hot’ 6.[g] ‘got’ Familiar IPA symbols, same sound:

20. English Phonemes Familiar IPA symbols, different sounds: 17. [j]‘yacht’“yod” 18. [i]‘heed’ 19. [e] ([ej])‘hayed’([ej] = a “diphthong”) 20. ‘hod’ 21. [o] ([ow])‘bode’([ow] = a “diphthong”) 22. [u]‘who’d’ A diphthong is a phoneme that combines two phones.

21. English Phonemes Unfamiliar IPA symbols, for consonants: 23. ‘thought’“theta”28. ‘chop’ 24. ‘though’“edh”29. ‘jot’ 25. ‘shot’“esh” 26. ‘vision’“ezh” 27. ‘ring’“engma”
