文中介绍了基于FB展开的语音信号表示的基本理论,并对用FB展开系数表示语音的能力进行了分析。提出了基于FB展开的语音转换算法,并对该算法进行了仿真实验。对转换后语音所进行的ABX测试表明,该算法能够较好的完成语音转换,转换后语音的自然度和目标人趋向度比较高。

In this paper,the fundamental theory of the speech signal＇ s expression based on FB expansion is described, and the ability of expressing speech signal with coefficients of FB expansion is analysed. The algorithm of voice transformation technology, based on Fourier-Bessel expansion is put forward, and the corresponding emulational experiment is carried out. The ABX test to the transformed signal shows that this algorithm performs well.
