Effects of auditory feedback on F/sub 0/ trajectory generation

A method is proposed to evaluate contributions of auditory feedback to speech F/sub 0/ trajectory generation. This method is based on data obtained in a series of new auditory feedback experiments (TAF: transformed auditory feedback) in which quantitative measurements were taken of interactions between speech perception and production under natural speech conditions. Experimental results revealed that the effects on power spectra of F/sub 0/ trajectories vary among subjects and that the maximum magnitude exceeds 10 dB.
