Psychophysics of Complex Auditory and Speech Stimuli
Abstract
A major focus on the primary project is to use of different procedures to provide converging evidence on the nature of perceptual spaces for speech categories. Completed research examined initial voiced consonants, with results providing strong evidence that different stimulus properties may cue a phoneme category in different vowel contexts. Thus, /b/ is cued by a rising second format (F2) with the vowel /a/, requires both F2 and F3 to be rising with /i/, and is independent o the release burst for these vowels. Furthermore, cues for phonetic contrasts are not necessarily symmetric, and the strong dependence of prior speech research on classification procedures may have led to errors. Thus, the opposite (falling F2 and F3) transitions lead somewhat ambiguous percepts (i.e., not/b/) which may be label consistently (as /d/ or /g/), but requires a release burst to achieve high category quality and similarity to category exemplars). Ongoing research is examining cues in other vowel contexts, and issuing procedures to evaluate the nature of interaction between cues for categories of both speech and music
