提出了一种基于矢量量化和频谱映射的语音转换技术。该技术的基本思想是制作映射码本，映射码本代表不同说话人的码本之间的对应关系。使用训练话语分别生成频谱参数、功率值和基音频率的映射码本。这项技术使得精确控制语音个性成为可能。为了评估这种技术的性能，听力测试进行了两种语音转换。一个是男性和女性说话者之间的转换，另一个是男性说话者之间的转换。在男-女转换实验中，所有转换后的话语都被判断为女性，在男-男转换实验中，65%的话语被识别为目标说话人。
The authors propose a new voice conversion technique through vector quantization and spectrum mapping. The basic idea of this technique is to make mapping codebooks which represent the correspondence between different speakers' codebooks. The mapping codebooks for spectrum parameters, power values and pitch frequencies are separately generated using training utterances. This technique makes it possible to precisely control voice individuality. To evaluate the performance of this technique, hearing tests are carried out on two kinds of voice conversions. One is a conversion between male and female speakers, the other is a conversion between male speakers. In the male-to-female conversion experiment, all converted utterances are judged as female, and in the male-to-male conversion, 65% of them are identified as the target speaker.>
