语音分析方法和装置、语音合成方法和装置、以及存储语音分析程序的介质
摘要：
本发明公开了语音分析装置和语音分析方法，该语音分析方法包括产生相对音高的时间序列的变量提取步骤。所述相对音高是从乐曲数据产生的在时间轴上连续波动的音高和参考语音的音高之差。所述乐曲数据按时间序列指定乐曲的各个音符。所述参考语音是通过歌唱所述乐曲而得到的语音。通过对其中未检测到音高的无语音区间进行插值处理来处理所述参考语音的音高。所述语音分析方法还包括特性分析步骤，其产生定义了用于表示在所述变量提取步骤中产生的相对音高的时间序列的模型的歌唱特性数据。
摘要（英）：

A voice analysis method includes a variable extraction step of generating a time series of a relative pitch. The relative pitch is a difference between a pitch generated from music track data, which continuously fluctuates on a time axis, and a pitch of a reference voice. The music track data designate respective notes of a music track in time series. The reference voice is a voice obtained by singing the music track. The pitch of the reference voice is processed by an interpolation processing for a voiceless section from which no pitch is detected. The voice analysis method also includes a characteristics analysis step of generating singing characteristics data that define a model for expressing the time series of the relative pitch generated in the variable extraction step.
