PESQ (Perceptual Evaluation of Speech Quality), nke ahaziri dị ka ITU-T P.862, na-ebu amụma àgwà okwu aghọtara, tumadi maka ule ekwentị na codec. Ọ na-atụnyere akara nrịbama dị ọcha na nke e merụrụ emerụ wee wepụta akara na nha nha MOS (ihe dịka -0.5 ruo 4.5), na-egosiputa nghọta mmadụ. STOI (Ebumnobi Nghọta nke Obere Oge), ewepụtara na 2010, kama na-ebu amụma nghọta: ole okwu onye na-ege ntị ga-aghọta n'ezie. Ọ na-ejikọta envelopu oge dị mkpirikpi nke okwu dị ọcha na nke edoziri n'ofe ugboro ugboro, na-emepụta akara site na 0 ruo 1. Ha abụọ bụ metrics intrusive (ntụgharị aka). PESQ zara 'ọ dị mma?' mgbe STOI na-aza 'ị nwere ike ịghọta ya?' Ọnụ ha bụ ngwaọrụ nleba anya nke ndabara maka nkwalite okwu, ịkatọ, na sistemụ nkwuwa okwu.

Maapụ PESQ abụọ na-egosi n'ọ̀tụ̀tụ̀ ụda olu psychoacoustic (Bark bands), na-agụta ọgba aghara nghọta ka oge na-aga, ma weghachi ya na uru MOS. STOI na-ekewa okwu n'ime otu ụzọ atọ-octave band, were obere ~400 ms envelopu akụkụ, obere vidiyo wee hazie ha, wee gbakọọ njikọ dị n'etiti ntụnye aka na envelopu rụrụ arụ.
