Voice quality assessment is an emergent aspect in Global System for Mobile Communications (GSM) network. The evolution of GSM also able in principle to take benefit from end to end services.GSM network inherently include elements such as noisy intermediate equipments that degrade the quality of transmitted voice signal. GSM network presents an alternate method to improve quality and customer experience based on International Telecommunication Union (ITU)-TG107. This paper provide overview of voice quality in GSM network by presenting the methods for voice quality enhancement, functionality of Voice Enhancement Device (VED).
