Compensatory Speech Response to Time-Scale Altered Auditory Feedback

In this experiment, we examined speech compensation to time-scale altered auditory feedback during the transition of the semivowel for a target utterance of /ija/. We examined speech compensation and the after effect in terms of three acoustic features, the maximum velocities on the F1 and F2 trajectories (VF1 and VF2) and the F1-F2 onset time difference (TD) during the transition, as well as listening test on the feedback speech. As the result, speech compensation was observed in VF1, VF2 and TD. The magnitude of speech compensation in VF1 and TD monotonically increased as amount of the time-scale perturbation. Speech compensation for time-scale altered auditory feedback is carried out primarily by changing VF1 and secondarily by adjusting VF2 and TD. Also, it is activated mainly by detecting the speed change in altered feedback speech sound.
