PESQ
Problem: Manual Scoring is Labor-Intensive
– Training is required
– Variability of scores is tough to eliminate
Possible Solution = PESQ
– Perceptual Evaluation of Speech Quality (PESQ)
– Standardized as ITU-T Recommendation P.862
– Commercial software available (appx. $12k/license)
Issue: PESQ Scores Do Not Match DAQ Scores
– Option 1: Agree on mapping from PESQ to DAQ
– Option 2: Abandon DAQ and use PESQ score threshold
