统一通信Android客户端语音消息的实现

Implementation of Voice Message on UC Android Client

为了实现统一通信Android客户端语音消息功能并减少网络传输量,在使用XMPP的基础之上,通过分析Smack和Speex等关键技术,结合移动设备自身的特性,设计了移动端语音消息的收发机制,高效地实现了Android客户端的语音消息功能,并充分考虑用户体验,提供重发机制,通过移植Speex到Android平台,使用其完成编解码工作,极大地降低了压缩后输出文件的体积,减少了移动端的网络传输量。最后说明了实现效果,指出了未来的研究方向。

In order to implement the voice message function on the UC Android client and to reduce the network tmnsnfission traffic, the Rx/Tx mechanism of voice message on mobile client is designed by analyzing on key technologies such as Smack and Speex based on XMPP application and considering the characteristics of mobile equipment. This design implements efficiently the voice message functions on Android client and provides the resend mechanism by fully considering user experience. By migrating Speex to Android platform and making it complete CODEC, the size of output file is greatly decreased and the network transmi.s.sion traffic of the mobile client is reduced. Finally, the implantation effect is presented, and the future research direction is pointed out.
