| Abstract(in English) | Just by listening to the voice on a telephone, we can immediately tell whether the caller is an adult or a child, and we can estimate the speaker's height (size). At the same time, we can recognize the content of the speech regardless of the size of the speaker. According to the source-filter theory, speech sounds are generated by combining information about the shape of the vocal tract (filter characteristics) and the vibration of the vocal folds (source characteristics).Based on the speech chain theory, the auditory system could be assumed to solve the inverse problem. To model the mechanism, we proposed the Stabilized Wavelet-Mellin Transform (SWMT). As a background, we present the results of size perception experiments and show that the results cannot be explained by peripheral auditory models alone and that the spectral weight function, SSI weight, derived from the SWMT is effective. We also discuss how the SSI weight can improve the accuracy of vocal tract length estimates obtained from MRI measurements. Furthermore, we discuss the theoretical optimality of the SWMT and the gammachirp auditory filter. Finally, we mention the experimental measurement and estimation of their characteristics. |
