  Perceptual learning about voices is known to facilitate speech perception, but it is unclear exactly which phonetic representations are altered to cause this facilitation. This study examines perceptual learning for a non-segmental phonetic property, talker-specific cues to word boundaries. An experiment tested intelligibility in noise of sentences that contained hard-to-segment sequences (e.g. /patsɔːd/, which can correspond to Pat sawed or Patís awed). Testing occurred before and after training with a voice; improvement in performance after training was measured. Subjects who heard the same voice during training as during testing showed more improvement than those who heard a different voice. Implications for exemplar theories of speech perception are discussed.

  Words repeated in the same voice are better recognized than when they are repeated in a different voice. Such findings have been taken as evidence for the storage of talker-specific lexical episodes. But results on perceptual learning suggest that talker-specific adjustments concern sublexical representations. This study thus investigates whether voice-specific repetition effects in auditory lexical decision are lexical or sublexical. The same critical set of items in Block 2 were, depending on materials in Block 1, either same-voice or different-voice word repetitions, new words comprising re-orderings of phonemes used in the same voice in Block 1, or new words with previously unused phonemes. Results show a benefit for words repeated by the same talker, and a smaller benefit for words consisting of phonemes repeated by the same talker. Talker-specific information thus appears to influence word recognition at multiple representational levels.

  This study aimed first to determine whether there is a delay associated with processing words in an unfamiliar regional accent compared to words in a familiar regional accent, and second to establish whether short-term exposure to an unfamiliar accent affects the speed and accuracy of comprehension of words spoken in that accent. Listeners performed an animacy decision task for words spoken in their own and an unfamiliar accent. Next, they were exposed to approximately 20 minutes of speech in one of these two accents. After exposure, they repeated the animacy decision task. Results showed a considerable delay in word processing for the unfamiliar accent, but no effect of short-term exposure.
