语音变速不变调软体化处理方法

A PROCEEDING METHOD OF CHANGING SPEECH SPEED WITHOUT THE TONE CHANGED IN SOFTWARE

语音变速不变调亦称语音时域压扩,可以满足学习外语、报告记录、语音研究及公安侦察等需要。我们把自然辩证法基本思想及物理学基本规律应用于声波研究之中,同时假设人的听觉感受器是按一份一份地接收声波所载的信息这一方式工作的,认为声波相对于听觉也有波粒二像性。基于这些发现,我们采用基于类正弦波的微元法进行语音时域压扩,实验中达到了变速不变调的效果,而且信噪比比较高。反过来,实验结果也一定程度上支持了听觉感受器工作模型假设以及声波相对于听觉的波粒二像性。

The technology of changing speech speed without the tone changed is named as one of expanding and deflating audio signal in the field of time,which can meet the demands of learning foreign languages,reporting records,researching audio and detecting evidences.The basic thoughts in the dialectic of nature and the basic laws in physics are applied to the research of audio wave.And the model is presumed that the ear of people receives the information in audio wave one by one.So it is believed that the audio wave shows the peculiarities in both wave and particle towards the sense of hearing.Thus the writers achieve the technology in the method of fraction based on dales and peaks of audio wave.In result the effect of changing speech speed without the tone changed is reached,and the ratio of signal to noise is higher.The experimental result supports the presumed model about hearing in some degree.
