Abstract
The stimuli were spoken vowel-consonant-vowel sequences in the frame “I say V1 C V2” in which V1 was /u, æ/, C was /p,t,k/and V2 was /a,i/ in all 12 combinations. Reaction time (RT) of practiced listeners was observed to the assigned final stressed vowel target (V2). Experimental manipulations were: (a) pre-stop-consonant silence either was or was not extended by 100–200 msec and (b) the sequence either was or was not cross spliced at the silent interval. Extended silence alters the acoustic-phonetic structure of the stimulus, and it possibly allows extra time to process appropriate anticipatory cues (if any), or inappropriate anticipatory cues (if any) when cross spliced, to the target vowel. Among the results discussed are both relatively faster and slower RT which were produced by these manipulations and their interactions with target. [Supported by ARIBSS.]
