摘要
在日常生活通信中,语音起着至关重要的作用.然而,环境噪声污染问题严重影响着语音处理系统的性能.为有效应对噪声干扰问题,可以采用语音增强技术.语谱图作为一种融合了时域和频域优势的工具,能够清晰地揭示语音频谱随时间的变化情况.因此,文章基于语谱图进行滤波去噪,旨在提升语音的质量,使其更加清晰可辨.
Abstract
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.
