Research on The Denoising Algorithm of Speech Signal

摘要

The wavelet transform and Hilbert-Huang transform (WT) are the important methods in signal processing and each has advantages and disadvantages. In this paper, we analyzed the speech denoising methods based on wavelet transform and HHT and pointed out the characteristics. The method based on HHT and WT was applied on speech denosing and the experiments show that the results is adapt to speech denosing. This kind of methods can have a further study.
