中文说明：
语音是人类交换信息的有效渠道之一，也是我们日常生活交流的主要形式。 语音与当今科学技术的快速发展息息相关，特别是计算机中的语音交互技术，通 过对语音信号进行采集和处理，实现人与人之间有效信息的传输、获取以及存储。 基于 MATALAB 的语音信号去噪设计，对噪声信号进行有效地滤除，将降噪后的语音信号与原始 信号在时域和频域进行对比分析，计算出信噪比，并在 MATLAB 中设计 GUI 仿 真界面进行展示。
English Description：
Voice is one of the effective channels for human to exchange information, and it is also the main form of communication in our daily life. Voice is closely related to the rapid development of science and technology, especially the voice interaction technology in computer. Through the acquisition and processing of voice signals, effective information transmission, acquisition and storage between people can be realized. The design of speech signal denoising based on MATALAB can effectively filter the noise signal. The denoised speech signal is compared with the original signal in time domain and frequency domain, and the signal-to-noise ratio is calculated. The GUI simulation interface is designed in MATLAB for display.
