Perceptual Evaluation of Speech Quality (PESQ)
https://www.microtronix.ca/pesq.html
The PESQ Algorithm is designed to predict subjective opinion scores of a degraded audio sample. PESQ returns a score from 4.5 to -0.5, with higher scores indicating better quality. PESQ is designed to analyze specific parameters of audio, including time warping, variable delays, transcoding, and noise.
