PESQ can be applied to provide an end-to-end (E2E) quality assessment for a network, or characterize individual network components. PESQ results principally model mean opinion scores (MOS) that cover a scale from 1 (bad) to 5 (excellent). A mapping function to MOS-LQO is outlined in Recommendation ITU-T P.862.1.
POLQA, similar to P.862 PESQ, is a Full Reference (FR) algorithm that rates a degraded or processed speech signal in relation to the original signal. It compares each sample of the reference signal (talker side) to each corresponding sample of the degraded signal (listener side). Perceptual differences between both signals are scored as ...
ITU-T Recommendation P.862 (2001-02): Perceptual evaluation of speech quality (PESQ): An objective method for end-to-end speech quality assessment of narrow-band telephone networks and speech codecs "AES Journal Forum » A Perceptual Speech-Quality Measure Based on a Psychoacoustic Sound Representation". secure.aes.org.

PEAQ results principally model mean opinion scores that cover a scale from 1 (bad) to 5 (excellent). The Subjective Difference Grade (SDG), which measures the degree of compression damage (impairment) is defined as the difference between the opinion scores of tested version and the reference (source). The SDG typically ranges from 0 (no ...
Mean opinion score (MOS) is a measure used in the domain of Quality of Experience and telecommunications engineering, representing overall quality of a stimulus or system. It is the arithmetic mean over all individual "values on a predefined scale that a subject assigns to his opinion of the performance of a system quality". [ 1 ]

The Circuit Merit system is a measurement process designed to assess the voice-to-noise ratio in wired and wireless telephone circuits, [1] especially the AMPS system, [2] and although its reporting scale is sometimes used as input for calculating mean opinion score, [3] the rating system is officially defined relative to given ranges of voice-to-noise ratios.
Hearing-Aid Speech Quality Index (HASQI) is a measure of audio quality originally designed for the evaluation of speech quality for those with a hearing aid,. [1] [2] It has also been shown to be able to gauge audio quality for non-speech sounds and for listeners without a hearing loss.
