Research on the Method of Chinese Speech Retrieval

According to the characteristic of the Chinese speech, we propose a method of retrieving the Chinese speech based on wavelet transform in this paper. At first we preprocess the data in the warehouse to provide the high quality speech data. And then we divided the speech samples into subsections and pick up the character of them. Finally, based on the Euclid distance of scale parts, we retrieve the speech sample contains similar subsections which is the result.
