基于正弦模型的汉语语音时长和音高的修正

Time-scale and Pitch Modification of Chinese Speech Based on Sinusoidal Model

把一种基于语音的正弦模型的音高和时长修正算法应用于汉语普通话语音的韵律调整 ,可调范围比较大 ,而且保证了合成语音的清晰度与自然度 .非正式测听结果表明 :该算法是一种很适合汉语语音的韵律调整的算法 .

In this paper time scale and pitch modification technique based on sinusoidal model is presented for Chinese speech prosodic modulation.The technique is adapted for a wide range of transformation while retaining a great degree of naturalness.The result indicates that this technique is very suitable for Chinese speech prosodic modulation.
