The results of experimental researches of voice traffic processing, retransmission and routing in networks with dynamically adaptable architecture are given in the paper. The structure of the developed prototype of communication system is also considered. This system is capable to operate in wireless sensor ZigBee networks. The measured values of actual system working features when transmitting voice streams in half-duplex communication mode are presented. The researches are based on biometric access control systems, which are currently the most promising ones, since the necessity of implementing personnel identification is required in many spheres of human activity. The urgency of the work is also confirmed by widespread wireless mobile telecommunication technologies on which data transmission in the developed system is based. On the basis of spectral and other characteristics of voice, the permission to perform any actions will be given. Practical realization of voice communication application for using it together with ZigBee modules and the researches of characteristics of its work confirmed the real applicability of ZigBee networks for voice message exchange.
