VoIP Signal Processing in Digital Domain

The transmission of Voice over Internet Protocol (VoIP) requires signal processing for reliable and efficient performance over the computer and the communication platform. Speech quality, as perceived by the users of VoIP telephony, is critically important to update the service. Signal quality is degraded by network layer problems, including delay, jitter and packet loss. This paper presents a simulation model for VoIP and a simulative analysis of VoIP. The digital filtering algorithm is implemented on degraded VoIP speech signal
