Abstract

[Wavelet transform (WT) provides a way to explore the characteristics of nonstationary speech signals. Both time and frequency analysis can be conducted by WT. The tree structure of WP analysis can be customized to the critical bands of human hearing giving better spectral estimation for speech signal than other methods. Wavelet-based pitch estimation assumes that the glottis closures are correlated with the maxima in the adjacent scales of the WT. This approach ensures more accurate estimation of pitch period.]
