Production and perception of individual speaking styles

As explanation of interspeaker differences in speech production moves beyond sex‐ and age‐related differences in physiology, discussion has focused on individual vocal tract morphology. While it is interesting to relate, say, variable recruitment of the jaw to extent of palate doming, there is a substantial residue of arbitrary differences that constitute the speaker’s ‘‘style.’’ Style differences observed across a well‐defined social group indicate group membership. Other style differences are idiosyncratic ‘‘habits’’ of articulation, individual solutions to the many‐to‐many mapping between motoric and acoustic representations, which may be set in place in the initial acquisition of motor‐control representations for speech. Perceptual studies of social style differences suggest that perceptibility depends upon the task and upon the hearer’s own group membership. The few studies of idiosyncratic differences suggest that speakers perceive each others’ productions in terms of their own habits. Thus, percept...
