| Abstract: | Vocal tract warping functions for normalizing vocal tract transfer functions of seven male subjects were calculated based on a vocal tract deformation method based on the vocal tract length sensitivity function. Vocal tract area functions for the five Japanese vowels of six subjects were tuned for their first four formant frequencies to be close to those of a target subject. The vocal tract warping functions were obtained as relationship between the original and deformed area functions. The results indicate that (1) the warping functions are not linear functions, (2) the vocal tract length of the deformed area functions are different from that of the target subject, and (3) the shape of the warping functions of the five vowels are not constant for each subject. |
