Research on Speech Enhancement Technology Based on Spectrogram Filtering and Denoising
In daily communication,phonetics plays a vital role.However,the problem of environmental noise pollution seriously affects the performance of speech processing system.In order to effectively deal with noise interference,speech enhancement technology can be adopted.As a tool that combines the advantages of time domain and frequency domain,spectrogram can clearly reveal the changes of speech spectrum with time.Therefore,this paper carries out filtering and denoising based on spectrogram,aiming at improving the quality of speech and making it more legible.
