Abstract
These studies examined the perceptual role of various components of naturally produced stop consonants (/b, d, g, p, t, k/) in CV syllables. In the first experiment, the context-sensitive voiced formant transitions were removed with a computer-splicing technique. Identification accuracy was 84% when the consonant was presented with the same vowel as had been used to produce it. Performance fell to 66% when the consonant was juxtaposed with a different vowel. The second experiment not only deleted the voiced formant transition, but also replaced the aspiration with silence. Here, identification accuracy dropped substantially, especially for voiceless stops, which had contained devoiced formant transitions in the replaced interval. The pattern of errors suggested that listeners try to extract the missing locus of the consonant from the vowel transition, and in the absence of a vowel transition, they try to extrapolate it from the second formant of the steady-state vowel.
