Modified Digital Filtering Algorithm to Enhance Perceptual Evaluation of Speech Quality (PESQ) of VoIP

By Imran Ghous Tahir Muhammad Habibullah Jamal

DOI: https://doi.org/10.5815/ijigsp.2013.04.02, Pub. Date: 8 Apr. 2013

Speech quality of VoIP system is degraded due different network layer problems such as packet loss delay and jitter and external noise. This paper compares the quality of speech signal that is implemented on digital signal processor using G.729 audio data compression algorithm with the ITU-T G.711 PCM coder implemented using modified digital filtering algorithm. PESQ (ITU-T P.862, Perceptual Evaluation of Speech Quality) is used to evaluate the performance. The results indicate that our proposed architecture has better performance.
