摘要
Abstract
A speech synthesis technology based on optimal phase design is proposed. It can effectively reduce the chance of saturation distortions caused by the unbalanced waveform for the synthesized speech signal in the MBE vocoder. Moreover,to ensure the stability of the synthesizing filter, the line spectral frequency (LSF) coefficient extracting is optimized. The experimental results show that the synthesized speech signal waveform displays an approximate balanced distribution up and down from the zero amplitude value,and that the speech sounds without uncomfortable feeling. It is justified from the experimental results that the synthesized speech quality can be effectively improved by using the proposed speech synthesis technology based on the optimal phase design and the optimized LSF coefficient extracting.关键词
