========================================================================== PESQ measure: ------------- Usage of the PESQ objective measure is as follows: [pesq_mos]=pesq(cleanfile.wav,enhanced.wav) where 'cleanfile.wav' contains the clean speech file and 'enhanced.wav' contains the enhanced file. Example: To run the PESQ objective measure with the example files provided, type in MATLAB: >> pesq('sp09.wav','enhanced_logmmse.wav') ans = 2.2557 Source code for the PESQ implementation is available from a CD-ROM included in the following book: Loizou, P. (2007) "Speech enhancement: Theory and Practice", CRC Press. ======================================================================== COMPOSITE MEASURE: ----------------- Usage: [Csig,Cbak,Covl]=composite(cleanfile.wav,enhanced.wav) where 'Csig' is the predicted rating of speech distortion 'Cbak' is the predicted rating of background distortion 'Covl' is the predicted rating of overall quality. You may run example files included in the zip file. In MATLAB, type: >> [c,b,o]=composite('sp09.wav','enhanced_logmmse.wav') LLR=0.681368 SNRseg=3.991727 WSS=49.671978 PESQ=2.255732 c = 3.3050 b = 2.6160 o = 2.7133 where 'sp09.wav' is the clean file and 'enhanced_logmmse.wav' is the enhanced file. The predicted ratings for overall quality was 2.7133, for background was 2.61 and for signal distortion it was 3.3050. Any questions, please email: loizou@utdallas.edu
