| Abstract | Investigated whether perceptually isochronous (I) sequences have articulatory correlates. EMG potentials were recorded from the orbicularis oris muscle when 1 male and 4 female adult speakers produced sequences of monosyllables "as if speaking in time to a metronome." Sequences were devised so that lip-muscle activity was related to the syllable-initial consonant, the stressed vowel, or the stressed vowel and final consonant. Results indicate that I muscular activity accompanied both I and anisochronous acoustic signals produced under instructions to generate I sequences. These findings support an interpretation of the perceptual phenomenon reported by J. Morton et al (see PA, Vol 57:2826) to the effect that listeners judge isochrony of the talker's articulations as they are reflected in the acoustic signal. |
