One of the important aspects of mobile communication industry is satisfying costumers’ needs most economically. Indeed, customers expect good and consistent quality of service from the provider. In mobile telephony, this amounts to controlling the speech quality as “perceived” by the customers. Controlling the perceptual speech quality necessitates reliable measurement of the quality first, followed by exercising direct control on it. The end-users’ quality has traditionally been monitored and controlled based on radio link measurements such as the C/I, BER, or FER. For telephony, because of the characteristics of speech signals, these measurements are unreliable indicators of the quality "perceived" by the end-user.
