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.(Speech is one of the effective ways for human to exchange information, and it is also the main form of our daily life communication. Speech is closely related to the rapid development of modern science and technology, especially the voice interaction technology in the computer. Through the acquisition and processing of voice signals, the transmission, acquisition and storage of effective information between people and people is realized. Based on the noise signal de-noising design of MATALAB, the noise signal is effectively filtered, the speech signal and the original signal after the noise reduction are compared and analyzed in the time domain and frequency domain, and the signal to noise ratio is calculated, and the GUI simulation interface is designed in the MATLAB.)
