摘　　要：信息隐藏技术对于版权保护和通信保密非常重要。论文将信息隐藏技术用于实现语音安全通信,对语音安全通信的一种新方法——语音回声隐藏技术进行分析和研究,给出了实现该技术的系统方案,并进行仿真和分析,从人耳听觉特性具体要求的角度讨论了该系统的实现细节。Information hiding technology is very important for copyright protection and secret communication. In this paper, based on the concept of information hiding, we proposed a secure voice communication system. By introducing echo into voice signal, secret information can be hidden in exoteric information. The scheme is simulated and analyzed on its performance. The details of the scheme are also discussed from the point of the sensitivity of hominine hearing.
