Perceptual Evaluation of Speech Quality (PESQ)
Telecommunications Objective Speech Quality Assessment (TOSQA and TOSQA2001)
These methods are used for objectively modeling the results of listening tests. They provide a result that could be expected if the recorded speech were subjectively rated by test persons.
PESQ and TOSQA can be used in scenarios where the input and output of the measured object are both electrical interfaces. By contrast, TOSQA2001 allows the assessment of terminals as part of the transmission path because it is validated for both acoustical and electrical interfaces as well as wideband measurements.
