Following the technique described in the work of R. M. Warren et al. ['Auditory Sequence: Confusion of Patterns Other Than Speech or Music,' Science 164, 586 (1969)] concerning the perception of temporal order in a continuously repeated sequence of four sounds, we investigated the duration of the four (equal) segments necessary for correct perception of the temperal order of four vowel sounds. The vowels chosen were /i/, /ε/, /a/, /u/; all vowel samples were spliced from the enunciations of one speaker (PBH) and were controlled for pitch (125 Hz) and true rms intensity. The duration of each vowel segment, T, was varied from 75 to 300 msec; vowel order was randomized for each value of T. In identifying temporal order, listeners achieved near perfect scores (>90%) for T>=125 msec; for T<=100 msec, scores were near chance (16.7%). The marked difference between the segment durations (T) necessary for correct perception of temporal order for vowels (T≈100 msec) and nonspeech sounds (T from 300 to 700 msec) suggests that this technique can provide a sensitive measure of the 'speechlikeness' of synthetic stimuli.
