Duration effects on labeling of tonal analogs to F1‐cutback continua

Abstract

F1 cutback has been demonstrated to be at least a contributing cue, and very possibly a major cue, for the perception of voicing contrasts. In an attempt to evaluate the feasibility of there existing an acoustic basis for the role of F1‐cutback cues in the perception of voicing stimuli, our recent research has focused on comparing stimulus cue dependencies for voicing boundaries with similar stimulus changes in analogous tonal stimuli varying in complexity. An earlier paper [Pastore et al., J. Acoust. Soc. Am. 75, S65 (1984)], described parallel labeling boundaries as a function of tonal analogs to F1 frequency and F2 transitions, but no stimulus duration. We now have identified conditions under which our F1‐cutback analog stimuli exhibit both labeling boundary locations, and changes as a function of duration, which are characteristic of voicing boundaries for speech stimuli.
