Coarticulation Study 1

Stimuli: 12 CV syllables (four fricatives in three vowel contexts: i, u, a;

e.g., si, su, sa) Computer excised the vowel portion of each

syllable.

Procedure: Remaining "consonant" portion played to subjects.

Task: Identify the missing vowel.

Results: [i], [u] reliably identified; [a] not

Conclusion: Fricative portion contains information about vowel

Coarticulation Study 2 -1

Stimuli: C1VC2 syllables with [b]: bVb 9 different vowels: beeb, bib, babe, bobComputer divided syllables in X Y Z

X: transition from C1 to V (Y); Z: transition from V to C2; Y central vocalic (vowel) portion

Procedure: Subjects heard: 1. XYZ

2. X—Z (— is a silent gap) 3. Y (steady state portion) 4. Y (fixed length steady state portion)

5. XZ

Task: Identify the vowel in each test stimulus

Coarticulation Study 2 - 2

Results: Types 2 (X—Z), 1 (XYZ) accurate Types 3, 5 "significantly more errors" Type 4 worst

Conclusion: "…formant transitions and vowel duration are more important cues to the identity of vowels than a fixed sample of the steady- state information." (126 b)

1) domain specific

2) operates on a mandatory basis

3) fast

4) unaffected by feedback (from oth

er modules)

Visual Influences on Speech Perception

Procedure: Present visual picture of someone saying [ga] Synchronized with the sound [ba]

Task: Subject identifies the sound heard

Result: Subject "hears" and identifies it as [da]

Conclusion: Place of articulation detected by eye Manner of articulation detected by ear

Word-Superiority Effect -1

Stimuli: words, non-words, letters

Procedure: Show subjects one of these using tachistoscope briefly: word (a word) owrd (a non-word) d or k (a letter)

Task: Reply to "Did you see a given letter (e.g.,

"d") in final position?"

18

Word-Superiority Effect - 2

Results: More accurate if the letter appeared

in a word.

Conclusion: The word has an effect on letter

recognition. There must be some top-

down processing— though bottom-up

processing can occur
