Abstract :
The speech of the VoIP system is degraded by network layer problems which include delay, packet loss and jitter. The implementation of signal through digital signal processor can improve the quality of degraded VoIP signal. The work in this paper deals with the implementation of digital filtering algorithm on degraded VoIP speech signal. The results of implementation experiment indicate the improvement of signal quality. The results are validated through the measurement of enhancement signal using perceptual evaluation of speech quality (PESQ) measurement.
