| Abstract: | An approach of the pitch detection for obtaining speech tone of Chinese trisyllabic words on the basis of the wavelet transforms is proposed . Based upon the application of wavelet transforms to detecting the sharp variations of signals,multiscale imformation is analyzed,and the pitch detection of Chinese trisyllabic words is accurately performed.A fast algorithm of wavelet transforms is also given. |
