一种调整汉语语速的新方法

本文针对ＰＳＯＬＡ算法会引起频域上的不连续，提出了一种汉语语速调整的新方法。该方法基于语音的正弦模型理论，把每一帧短时语音信号分解为一系列不同幅值、相位 和频率的正弦分量，然后进行语速的调整，实验结果表明，合成的语音信号保持了原有语音的清晰度和自然度。

A New Method of Articulation Rate Modification for Chinese Speech

In order to overcome the discontinuities in the frequency domain of the TD PSOLA algorithm,a new method is proposed based on the sinusoidal presentation of speech.Each frame of speech signal is decomposed into sinusoidal components of different magnitudes and phases.The experiments in time scale modification show that the synthesized speech has the same quality as the original.
