Abstract:
This research was motivated by recent observations of a relatively strong perceptual salience of phase relations among harmonics in the vowel sound /ae/ [Carlson et al., J. Acoust. Soc. Am. 65, S6(1979)]. Phase had contributed relatively weakly to timbre in classical psychoacoustical studies using complex tones. We investigated the audibility of phase changes in vowels and complex tones using a forced-choice paradigm in which subjects discriminated between sounds presented with all harmonics in phase and a similar stimulus with a phase shift for the even harmonics that was varied from 0 to 90 degrees. “Phase discrimination thresholds” were obtained by determining the phase shift needed to produce criterion discrimination performance. Our preliminary findings indicate no major differences between the audibility of phase changes for vowel sounds and complex tones. Its joint dependence on fundamental frequency and number of harmonics is consistent with results in the literature. These findings are also compared to the audibility in vowel sounds of phase shifts as produced by the vocal tract.
