Abstract

This study attempts to achieve modeling simulation of the well-known phenomenon of online compensation for pitch-shifted auditory feedback. We used the Target Approximation (TA) model as the underlying kinematic mechanism of pitch contour generation, and simulated feedback compensation through responsive perturbation of the height parameter of the TA model. Results show that both withinsyllable and cross-syllable pitch compensation in disyllabic utterances can be replicated. Furthermore, our data analysis also revealed an over-rectification phenomenon. By adjusting the height parameter back and beyond its original value after the compensation, the over-rectification was also replicated, further improving the overall simulation results.
