In the present paper quality of voice has been analyzed in VoIP communications model. An investigation of IP-based voice communication with emphasis on the effects of a wireless channel on the quality of the received speech is attempted and the effects of voice signal compression and wireless channel conditions, as well as channel coding on the voice quality and recognition, are investigated through simulation. Simulation is implemented using Matlab and Speex software.
