| 摘 要： | 基音周期变换是文—语转换和语音转换的重要内容。在语音转换中有很多作者主张基于LPC分析来实现语音转换,通过直接或间接调整LPC系数来实现频谱包络的转换,而基音周期的转换则通过对LPC激励谱或LPC残差的处理来实现。提出对LPC残差用频域法来进行处理,得到改变了基音周期的LPC残差,从而实现语音的基音周期的变换。这种方法也可以用于文—语转换的基音周期改变中。

| Abstract: | Pitch modification is an important part in text to speech synthesis and voice conversion. In voice conversion, many authors in favor of realizing the voice conversion by the method based on LPC analysis, with which the spectrum envelope is converted by modifying the LPC coefficients directly or indirectly and the pitch modification is realized by processing the LPC excitation spectrum or LPC residual. Frequency method is proposed to process the LPC residual, then the pitch modified LPC residual is got. This method can also be used in the pitch modification of the text to speech synthesis. |
