摘　　要：本文介绍了一种语音压缩算法的代码移植及测试结果分析,从压缩算法在语音处理方面的特点出发,分析了Codec2语音编解码算法在传输中的优越性,并基于特定处理器硬件平台进行代码移植。文中论述了Codec2语音处理的算法原理、硬件电路的框架,以及代码的移植过程。该处理系统实现了语音的采集压缩以及传输,并通过测试表明该算法在低码率情况下具有低时延的特点。This paper introduces the code transplantation of a speech compression algorithm and the analysis of the test results. Starting from the characteristics of the compression algorithm in speech processing, the superiority of the Codec2 speech encoding and decoding algorithm in transmission is analyzed, and the code is transplanted based on a specific processor hardware platform. This paper discusses the algorithm principle of Codec2 speech processing, the frame of hardware circuit, and the transplanting process of the code. The processing system realizes the acquisition, compression and transmission of speech, and the test shows that the system has the characteristics of low bit rate and low delay.
