Purpose: The purpose of this study was to examine speech compensation in response to time-scale-modified auditory feedback during the transition of the semivowel for a target utterance of /ija/. Method: Each utterance session consisted of 10 control trials in the normal feedback condition followed by 20 perturbed trials in the modified auditory feedback condition and 10 return trials in the normal feedback condition. The authors examined speech compensation and the aftereffect in terms of 3 acoustic features: the maximum velocities on the (a) F1 and (b) F2 trajectories (VF1 and VF2) and (c) the F1-F2 onset time difference (TD) during the transition. They also conducted a syllable perception test on the feedback speech. Results: Speech compensation was observed in VF1, VF2, and TD. The magnitudes of speech compensation in VF1 and TD monotonically increased as the amount of the time-scale perturbation increased. The amount of speech compensation increased as the phonemic perception change increased. Conclusions: Speech compensation for time-scale-modified auditory feedback is carried out primarily by changing VF1 and secondarily by adjusting VF2 and TD. Furthermore, it is activated primarily by detecting the speed change in altered feedback speech and secondarily by detecting the phonemic categorical change.
