Abstract：For the disadvantages of a present mine voice communication system, a kind of wireless voice communication system based on ZigBee is put forward.The paper provides detailed information about hardware and software of wireless voice communication nodes.In the system, we use CC2530 as RF sending-receiving unit of a voice communication node, convert speech signals to digital or analog siginals by CSP1027, encode or decode quantized voice data by AMBE voice codec technology and realize voice message two-way wireless communication over the ZigBee wireless communication protocol IEEE 802.15.4 between voice communication nodes.Experiments have shown that a voice communication node can obtain a clear voice and have a high reliability in the effective distance of communication, meeting the requirements of voice communication.
