8 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 Yeni-Komshian, Grace H. and S.D.

9 Coarticulation Study 2 -1 Stimuli:C1VC2 syllables with [b]: bVb 9 different vowels: beeb, bib, babe, bob Computer 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
10 Coarticulation Study 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."

18 Word-Superiority Effect - 2 Results: More accurate if the letter appeared in a word. Conclusion: The word has an effect on letter recognition.
