语音基音检测的多分辨率分析法

The Application of Multiresolution in Pitch Detection

介绍了一种语音基音检测的多分辨率分析法。它将语音在不同的分辨率下判决出基音，然后相互比较得出正确的基音。还比较了它与两种传统方法的性能。实验结果说明，多分辨率分析法具有精度高、抗干扰能力强的特点。

A multiresolution algorithm is introduced in this paper to detoct the pitch of speech signals. The voice pitches are judged by the algorithm in different resolodhns, and the right one is educed through comparing pitches with each other. This paper also compared multiresolutionalgorithm with two traditional methods in the aspect of ahti-noise and complexity. The experimental results show that the multiresolution algorithm has the characteristic of high accuracy and high disturbance resistibility.
