数字信号处理技术是将模拟信息(如声音、视频和图片)转换为数字信息的技术。DSP通常指的是执行这些功能的芯片或处理器。它们可能也用于处理此信息然后将它作为模拟信息输出。本文利用这些方法结合起来,同时利用MATLAB工具对语音信号进行了分析,解决实际工程技术问题的能力。 Digital signal processing technology is the technology that converts analog information, such as sound, video and pictures, into digital information. DSPs generally refer to the chip or processor that performs these functions. They may also be used to process this information and then output it as simulation information. In this paper, the combination of these methods, while using MATLAB tools for voice signal analysis, the ability to solve practical engineering and technical problems.
