Modified Digital Filtering Algorithm to Enhance Perceptual Evaluation of Speech Quality (PESQ) of VoIP [PDF]
International Journal of Image, Graphics and Signal Processing, 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 ...

Enhancements in encoded noisy speech data by background noise reduction
Intelligent Systems with Applications, 2023 In this paper, we present recent improvements incorporated into an earlier speech encoding system that combined spectral subtraction with voice activity detection (SS-VAD) and linear predictive coding (LPC). The presence of background noise in the speech
