Abstract

|
The normal aging process on speech production and these changes are perceived by listeners. This study examined whetherage perception changed under various conditions of prosodic manipulations in normal listeners, comparing the prosodicchanges according to age and sex in adulthood. The older and younger voices were resynthesized by manipulation of thespeaking rate and pitch to shift the perceived age of the groups toward each other. Two-way repeated ANOVA wereconducted to determine if the prosodic type of resynthesized cue resulted in a significant shift in perceived age of young andold voices. The manipulation of the speaking rate resulted in a significant shift in perceived age for the older and youngergroups. A significant shift in age estimates was not observed for the younger male group when pitch was manipulated. Therewere significant gender-by-age group interactions for prosodic manipulation type. Age-related changes in the prosodicproperties of speech may ultimately influence speech perception.
