Objective measures for quality assessment of noise-suppressed speech
Three objective measures are proposed to separately evaluate the speech distortion, noise reduction and overall quality of the processed speech signal enhanced by single channel speech enhancement algorithms. The proposed measures are derived in both time and frequency domains. The high correlations between the measurement results of the proposed approaches and subjective ratings demonstrate the effectiveness of the proposed evaluation methodology. Some hints and links between signal parameters and perceptual judgements are revealed in our analysis on the evaluation process of the proposed objective measures with subjective ratings.
