Phonological effects on the perceptual weighting of voice cues for voice gender categorization.

Voice perception and speaker identification interact with linguistic processing. This study investigated whether lexicality and/or phonological effects alter the perceptual weighting of voice pitch (F0) and vocal-tract length (VTL) cues for perceived voice gender categorization. F0 and VTL of forward words and nonwords (for lexicality effect), and time-reversed nonwords (for phonological effect through phonetic alterations) were manipulated. Participants provided binary "man"/"woman" judgements of the different voice conditions. Cue weights for time-reversed nonwords were significantly lower than cue weights for both forward words and nonwords, but there was no significant difference between forward words and nonwords. Hence, voice cue utilization for voice gender judgements seems to be affected by phonological, rather than lexicality effects.
