Abstract

Three experiments examined the perception of a 3-way voicing contrast by 77 naive monolingual (English-speaking) undergraduates. Laboratory training procedures were implemented with a small computer in a real-time environment to examine the perception of voiced, voiceless unaspirated, and voiceless aspirated stops differing in voice onset time. Three perceptual categories were present for most Ss after only a few minutes of exposure to the novel contrast. Subsequent perceptual tests revealed reliable and consistent labeling and categorical-like discrimination functions for all 3 voicing categories, even though one of the contrasts is not phonologically distinctive in English. Results demonstrate that the perceptual mechanisms used by adults in categorizing stop consonants can be easily and quickly modified with simple laboratory techniques.
