A Novel Non-Intrusive Voice Transmission Quality Measurement Algorithm based on Wavelet Transform
Jan Holub, Michael D. Street, Ondrej Tomiska · 2006
A new, wavelet-based, non-intrusive method for speech transmission quality measurements is described in the abstract. The discrete wavelet transform, unlike a Fourier transform, enables a significant reduction in the computational power required. In comparison with standardized methods (based on ITU-T P.563 algorithms), the described method saves about 90% of the operations needed, achieving about 90% of the results of P.563. Thus, it is suitable for continuous assessment, or even for applications embedded in the mobile terminal
