Abstract
An LPC analysis of a voice waveform is performed by an LPC analyzing circuit before analyzing vocal tract parameters by a vocal tract parameter analyzing circuit. The result of the analysis is converted into the components of source parameters by converting circuits and to eliminate the component of the source parameters from the voice waveform by an inverse filter. The components of the vocal tract parameters obtained by the analysis in the vocal tract parameter analyzing circuit is eliminated from the voice waveform through an inverse filter.
