For the ideal synthesis, USES a method of changing the long of frame to get pitch periods of given people natural four tones.

提出一种变长分帧的方法。为了较理想的合成出特定人的自然语音，采用变长分帧方法对特定人的自然语音的四声提取基音周期序列。

The proposed method restricted the frame length and frame shift to multiples of pitch period, called pitch synchronous algorithm;

该方法先将帧长和帧率都限制为基音周期的整数倍，即基音同步算法；
