摘　　要：传统的音频信号都是以模拟手段处理的,但存在抗干扰能力差、远距离传输受环境影响较大等弊端,而数字音频技术能很好解决这些问题。在数字音频技术中,音频数据交换是一个核心问题。针对广泛存在的语音信息,设计一种运行于DSP上的音频数据交换软件。首先概述了语音处理板的系统功能框架,其次设计一种基于DSP的语音处理板结构,最后重点设计语音处理模块软件的流程算法和通信控制协议。Traditional audio signals are processed by simulation,but there are many disadvantages,such as poor antiinterference ability,long distance transmission and so on.Audio data exchange is a key issue in digital audio technology.An audio data exchange software running on DSP is designed to solve the problem of speech information.Firstly,the system function frame of the speech processing board is summarized.Secondly,the structure of the speech processing board based on DSP is designed.Finally,the flow algorithm and the communication control protocol of the voice processing module are designed.
