Abstract

An improved Speex speech compression algorithm is proposed in this paper, which can be applied to speech transmission through wireless sensor networks (WSN). To overcome disadvantage of traditional Speex speech compression algorithm, the improved algorithm used the wavelet filter and Minimum Mean Square Error (MMSE) to replace the perceptual weighting filter and minimum perceptual weighted error module respectively, which are used in traditional algorithm. The simulation results show that the speech quality has been significantly enhanced after using this improved algorithm.
