Visual cues facilitate talker-specific perceptual adaptation within gender

Studies on perception learning typically use voices of different genders to differentiate between speakers, making it unclear whether the observed perception specificity proceeds by idiosyncratic talkers or different gender groups of talkers. We report an experiment that addresses this confound by investigating whether listeners show speaker-specific perception adaptation when the talkers are two females. The experiment shows that, when Speaker A has /s/-skewed sibilants and Speaker B has /ʃ/-skewed sibilants, the distributions offset each other within a gender group when pictures of the speakers are not available, while the /s-ʃ/ boundary shift was maintained in talker-specific ways when pictures of speakers became available. These results highlight the importance of top-down speaker-identity cues in perceptual adaptation, and give us a more complete picture of potential mediating roles of talker identity in different perceptual learning contexts.
