Accounts of the identification of words and talkers commonly rely on different acoustic properties. To identify a word, a perceiver discards acoustic aspects of an utterance that are talker specific, forming an abstract representation of the linguistic message with which to probe a mental lexicon. To identify a talker, a perceiver discards acoustic aspects(More)
In 5 experiments, the authors investigated how listeners learn to recognize unfamiliar talkers and how experience with specific utterances generalizes to novel instances. Listeners were trained over several days to identify 10 talkers from natural, sinewave, or reversed speech sentences. The sinewave signals preserved phonetic and some suprasegmental(More)
The personal attributes of a talker perceived via acoustic properties of speech are commonly considered to be an extralinguistic message of an utterance. Accordingly, accounts of the perception of talker attributes have emphasized a causal role of aspects of the fundamental frequency and coarse-grain acoustic spectra distinct from the detailed acoustic(More)
Theoretical and practical motives alike have prompted recent investigations of multimodal speech perception. Theoretically, multimodal studies have extended the conceptualization of perceptual organization beyond the familiar modality-bound accounts deriving from Gestalt psychology. Practically, such investigations have been driven by a need to understand(More)
A listener who recognizes a talker notices characteristic attributes of the talker's speech despite the novelty of each utterance. Accounts of talker perception have often presumed that consistent aspects of an individual's speech, termed indexical properties, are ascribable to a talker's unique anatomy or consistent vocal posture distinct from acoustic(More)
A series of experiments was conducted in which listeners were presented with audiovisual sentences in a transcription task. The visual components of the stimuli consisted of a male talker's face. The acoustic components consisted of : (1) natural speech (2) envelope-shaped noise which preserved the duration and amplitude of the original speech waveform and(More)

In two experiments, we investigated the creation of conceptual analogies to a contrast between vowels. An ordering procedure was used to determine the reliability of simple sensory and abstract analogies to vowel contrasts composed by naive volunteers. The results indicate that test subjects compose stable and consistent analogies to a meaningless segmental(More)
A perceiver who teams to recognize a talker becomes familiar with attributes of the talker's voice that are present in any utterance regardless of the linguistic message. Customary accounts of individual identification presume that such durable persona1 aspects of an individual's speech are independent of the acoustic properties that evoke segmental(More)
