Abstract:
The aims of this study are evaluating the quality level of a distortion speech signal based on the Signal-to-Noise Ratio (SNR), and active perception theory, and design an algorithm. The proposed algorithm is used to evaluate the distortion level of speech signal basing on the Unitary transform (U) of 1D signal, and on the calculation of similar strings of signal spectrum and distinctive indexes of signal distortion. 

Keywords:
DSP, theory of active perception, Signal-to-Noise Ratio, [SNR], U-transform,  distortion level, signal spectrum
