In spite of signal variability, listeners exhibit "phonetic constancy" in recovering the sequence of sounds (phonemes) and words intended by the talker. The focus here will be on the perceptual mechanisms that listeners use to deal with variability in the signal produced by variation in a talker's speaking rate. A series of studies will be described that examine what type of information talkers embed in the speech signal and the nature of the computations in perception that enable listeners to normalize for variation in speaking rate. A second series of studies will further examine listeners' normalization in a context of two voices. These studies focus on if/how a listener separates sounds (voices) into different sources, and how the processes that influence sound source separation interact with the listener's adjustment to the speaking rate of the talkers. The behavioral evidence reveal that the perceptual adjustment for speaking rate is an obligatory, autonomous process in perception and is readily influenced by information by voices other than the target talker.
