| Abstract(in English) | Vocal tract length normalization (VTLN) is an important issue in speech applications, such as automatic speech recognition and high-quality voice morphing. Individual spectral differences are primarily dependent on vocal tract length differences.They are also dependent on glottal source signal and the shape of pyriform fossa. This paper propose a new method for vocal tract length (VTL) estimation and normalization based on a gammachirp auditory filterbank (GCFB). VTLratios were estimated based on spectral distances between the same sentence spoken by 2 speakers. The calculation was carried out for all permutations of 28 speakers (_<28>P_<27> =756). Then the estimated error was calculated by the regression analysis. VTL estimation using the mel-frequency filterbank (MFFB), which is a preprocessor for calculating MFCCs commonly used in ASR, the gammatone fileterbank(GCFB) and the gammachirp filterbank(GCFB). The results indicated that the proposed GCFB-based VTL estimation outperforms the MFCC-based and the GTFB-based methods in the objective evaluations. |
