Abstract
As powerful and practical engineering software, MATLAB is used in data analysis and processing widely. This paper describes an example of separating noise from the raw speech. Firstly, high frequency noise is added to the speech signal. And then the principle of short time Fourier transform is analysis. Finally, a filter is designed to process the actual acquisition of a voice signal with noise. It is obvious that using Matlab software to process speech.
