PSQM — ( Perceptual Speech Quality Measure ) is a computational and modeling algorithm defined in ITU Recommendation ITU T P.861 that objectively evaluates and quantifies voice quality of voice band (300 3400 Hz) .It may be used to rank the performance… … Wikipedia
ILBC — (internet Low Bitrate Codec) это свободный от лицензионных отчислений кодек для голосовой связи через интернет. Кодек предназначен для узкополосных интернет каналов, со скоростью передачи аудио сигнала (человеческой речи) 13.33 кбит/с при длине… … Википедия
G.723.1 — is an audio codec for voice that compresses voice audio in 30 ms frames. An algorithmic look ahead of 7.5 ms duration means that total algorithmic delay is 37.5 ms.Note that this is a completely different codec from G.723.There are two bit rates… … Wikipedia
G.711 — is an ITU T standard for audio companding. It is primarily used in telephony. The standard was released for usage in 1972.G.711 represents logarithmic pulse code modulation (PCM) samples for signals of voice frequencies, sampled at the rate of… … Wikipedia

G.726 — is an ITU T ADPCM speech codec standard covering the transmission of voice at rates of 16, 24, 32, and 40 kbit/s. It was introduced to supersede both G.721, which covered ADPCM at 32 kbit/s, and G.723, which described ADPCM for 24 and 40 kbit/s.… … Wikipedia
G.729a — is an audio data compression algorithm for voice that compresses voice audio in chunks of 10 milliseconds. G.729a is compatible with G.729, but requires less computation. This lower complexity is not free since speech quality is marginally… … Wikipedia
