摘要
频谱包络转换是语音转换中的一项重要内容,基于双线性转换函数进行频谱搬移的方法可以有效地进行谱包络转换,而且在基于小语料库进行训练时仍能得到稳定的转换谱包络。本文基于LPC分析,提出用反傅里叶变换的方法来求解频谱搬移后的系统单位冲激响应,以此来实现频谱包络的变换,并取得了较好的效果。
Spectral envelope conversion is an important content of voice conversion. Based on bilinear transform function,spectral envelope can be efficiently converted even with small training speech database. In this thesis,based on LPC analysis,a method for calculating the spectrum converted system unit impulse function is proposed. So the spectral envelope is converted efficiently.
