Linux下语音实时通信的一种实现方法

An Approach of Real-Time Speech Communication Based on Linux

在设计嵌入式语音通信系统的过程中,提出了一种Linux下语音实时通信方法。利用Linux下OSS内核驱动实现了语音的采集和回放,基于LIVE库实现了RTP/RTCP的音频流的实时传输,并运用Linux下多线程技术,实现了语音的全双工数字通信。调试结果表明,该方法可以快速方便的实现语音的实时传输,对从事相关产品的开发具有一定的参考价值。

An approach was proposed that real-time speech communication based on Linux system during the period of embedded speech communication system designing. It has adopted the technology of OSS to complete the voice collection and replay, and realize the real-time transmission based on RTP/RTCP by the medium of LIVE storeroom, at the same time, it has made use of multithread technology to accomplish the speech communication on the full duplex. The experiments verify that the approach proposed above is really feasible and efficient. This approach will serve as references to the designs of the correlation products.
