摘要:

本文设计了一个语音信号分析处理系统并在Matlab环境下进行了实现。该系统能够实现信号的采集与播放,同时对语音信号进行时域分析与处理,获得信号的短时过零率,短时能量、短时自相关函数等参数。该系统充分利用了Matlab强大的数值计算、信号处理、图形显示等能力,具有使用方便,通用性强等优点。
>A speech signal analysis and processing system is realized in this paper under the Matlab environment. Signal acquisition and playback are also achieved in the system and a lot of time-domain parameters can be obtained while signal analysis is processing, such as short-term signal zero-crossing rate, short-time energy, short-time auto- correlation function, and so on. Powerful numerical calculation, signal processing, and graphics display capabilities of Matlab are fully used in this system. It is easy to use, and it has the versatility and other advantages.
