Articulatory synthesis using a vocal-tract model of variable length

Zhenli Yu, Shangcui Zeng

A method of articulatory synthesis using a vocal-tract model with variable length is proposed. The vocal-tract length is derived prior to the unique determination of vocal-tract area parameters incorporated with a codebook that maps formants to vocal-tract length is used. A two-dimensional interpolation function for irregularly spaced data is conducted to confine vocal-tract length in the first and second formant plain to generate the codebook. The reflection-type line analog (RTLA) model of articulatory synthesis is employed to generate speech sound. Variable vocal-tract length yields the issue of discretetime implementation with multi-rate sampling of the RTLA model. Multi-rate sampling conversion is conducted.
