The growth of Internet has led to the development of many new applications and technologies. Voice over Internet Protocol (VoIP) is one of the fastest growing applications. Calculating the quality of calls has been a complex task. The ITU E-Model gives a framework to measure quality of VoIP calls but the MOS element is a subjective measure. In this paper, we discuss a novel method using Random Neural...
Voice over Internet protocol (VoIP) is a technology that transports voice data packets across packet switched networks using the Internet protocol (IP). However, the current Internet, which was originally designed for data communications, provides best-effort service only, and does not guarantee to transmission quality. As known, packet delay dramatically degrades the quality of VoIP calls. It is...
This paper investigates the effects of temporal clipping on perceived speech quality. Temporal clipping usually results from voice activity detection (VAD), or line echo canceller's nonlinear processor, and the clipped speech portions are replaced by comfort noise. A nonintrusive algorithm is proposed to predict speech quality based on the clipping statistics. Mean opinion score (MOS) is used as a...
