Hello there! n Multiple levels of analysis n n Word order important (don’t say Hello there! n Multiple levels of analysis n n Word order important (don’t say “There Hello!”) Each word composed of a sequence of sounds Sentence is uttered in a particular tone of voice (signified by the “!”, rather than a “Hello there? ”) Used to signal particular part of a social interaction (would say it at the beginning of the interaction, not when leaving or in the middle)

Phonology n The sounds of a language n Phonemes, allophones & phones n n Phonology n The sounds of a language n Phonemes, allophones & phones n n Phonemes - abstract (mental) representations of the sound units in a language Allophones - different sounds that get categorized as the same phoneme Phones - a general term for the sounds used in languages Rules about how to put the sounds together n Includes sound structures like syllables, onsets, rhymes

Phonology allophones Listen to the ‘p’ sound pill [ph] spill [p] phonemes /p/ Rule: Phonology allophones Listen to the ‘p’ sound pill [ph] spill [p] phonemes /p/ Rule: If /p/ is used in word initial position you add aspiration (a puff of air), if word internal don’t aspirate

Finding phonemes n Substitution and minimal pairs n n Take a word (e. g, Finding phonemes n Substitution and minimal pairs n n Take a word (e. g, "tie" /ta. I/) and find the words that share the same sequence /a. I/, but contrast at their beginnings. If the switch in initial sound changes the meaning, it is evidence of separate phonemes n n pie, buy, tie, die, sigh, lie, my, guy, why, shy Gives us /p/ /b/ /t/ /d/ /s/ /l/ /m/ /g/ /w/ /sh/

Articulatory features n Point of articulation n Six major points: n n Larynx, soft Articulatory features n Point of articulation n Six major points: n n Larynx, soft palate, tongue body, tongue tip, tongue root, lips Manner How the articulator moves: nasality, aspiration, etc. n Configuration of other organs n n Voiced, rounded, etc.

Phonemes n Languages differ in two ways (with respect to phonology) – the set Phonemes n Languages differ in two ways (with respect to phonology) – the set of segments that they employ. • English has about 40 phonemes • Polynesian has ~11 Hawaiian • Khoisan (‘Bushman’) has ~141 listen to clicks - the set of phonological rules

Phonological Rules n Some non-words are “legal” and some are not – “spink” is Phonological Rules n Some non-words are “legal” and some are not – “spink” is okay – “ptink” isn’t – (but notice that apt is, as is captain) – In English the segment /pt/ isn’t acceptable in the word initial position

Psychological reality of phonemes n Miller & Nicely (1955) n n Participants were presented Psychological reality of phonemes n Miller & Nicely (1955) n n Participants were presented phonemes embedded in white noise. When they made mistakes, confusions between phonemes which varied by one feature were more common than those that varied by two features /b/ /p/ /d/ /t/

Psychological reality of phonemes n Liberman et al (1957) categorical perception of phonemes n Psychological reality of phonemes n Liberman et al (1957) categorical perception of phonemes n n Presented consonant-vowel syllables along a continuum The consonants were /b/, /d/, and /g/, followed by /a/ n n n for example, /ba/. Asked whether two syllables were the same or different Participants reported n n Various forms of /ba/ to be the same Whereas /ga/ and /ba/ were easily discriminated.

Phonology & morphology interaction n Allomorphs: different variations of the same morpheme Plural rule Phonology & morphology interaction n Allomorphs: different variations of the same morpheme Plural rule in English The plural morpheme takes the form: /-iz/ If the last sound in a noun is a sibilant consonant “churches” /-z/ if the last sound in a noun is voiced “labs” /-s/ if the last sound in a noun is voiceless “bets”

Psychological reality of Morphology n Speech errors n Stranding errors: The free morpheme typically Psychological reality of Morphology n Speech errors n Stranding errors: The free morpheme typically moves, but the bound morpheme stays in the same location n Morpheme substitutions n n n they are Turking talkish (talking Turkish) you have to square it facely (face it squarely) a timeful remark (timely) Where's the fire distinguisher? (Where's the fire extinguisher? ) Morpheme shift n n I haven't satten down and writ__ it (I haven't sat down and written it) what that add__ ups to (adds up to)

The result is an infinite number of syntactic structures from a finite set of pieces
