In a highly competitive telecommunication market where price differences have been minimised, quality of service (QoS) has become a critical differentiating factor. In the context of telecommunication systems, QoS is defined as the collective effect of service performance, which determines the degree of a users satisfaction with the service. Voice communication quality is one of the most visible and important aspects for QoS. Since voice quality is not generally guaranteed in an IP network, the ability to monitor and design for this quality is a top priority. From the point of view of ensuring quality design and management, methodologies for perceptual measurements for voice over IP (VoIP) networks are essential. This article reviews the development of perceptual quality measurements as mainly applied to VoIP networks.
