The acoustic features used to recognize talkers, such as pitch, timbre, and the acoustic effect of articulatory style, introduce large amounts of variability into the speech signal (reviewed by Nygaard, 2005). Natural speech provides the listener with a wealth of information, not only about what is said, but also about the identity of the talker. These findings suggest that listeners implicitly learn talker-specific information during a speech-comprehension task, and exploit this information to improve the comprehension of novel speech material from familiar talkers. interleaved) had no effect on this familiarity benefit. The type of talker presentation (blocked vs. The results showed that listeners had lower SRT when the speech was produced by the familiar talker than the unfamiliar talkers. For the other half, talkers varied randomly from trial to trial (interleaved paradigm). Half of the listeners performed a test session in which the four talkers were presented in separate blocks (blocked paradigm). Familiar and unfamiliar talkers were counterbalanced across listeners. In a final test session, listeners performed the same task, but this time they heard different sentences spoken by the familiar talker and three unfamiliar talkers. The sentences were mixed with noise, and listeners identified the verb within each sentence while their speech-reception thresholds (SRT) were measured. During four training sessions, listeners heard short sentences containing a single verb (e.g., “he writes”), spoken by one talker. The present study investigated whether speech comprehension benefits from implicit voice training that is, through exposure to talkers’ voices without listeners explicitly trying to identify them. In the real world, however, the characteristics of familiar talkers are learned incidentally, through communication. In most of these studies, talker familiarity was ensured by explicit voice training that is, listeners learned to identify the familiar talkers. Previous studies have shown that listeners are better able to understand speech when they are familiar with the talker’s voice. 4Department of Psychology, Humboldt University of Berlin, Berlin, Germany.
