Pesq numbers and clean speech comparison to processed speech
Well, I submitted my project. Thanks to the help of this group. 

As for the PESQ number, I think the range is between 1 and 5, where 5 being excellent and 1 is low.

Anyhow, I did another trick to estimate my performance. Instead of feeding the functions (SESQ, LLR, and Segment SNR) the clean speech and the processed speech, I fed them clean speech with the clean speech. I got numbers and these were my reference (or maximum) numbers. Then I compared all my runs against these reference numbers
