PESQ ak STOI Kalite Kaddu
PESQ ak STOI ay metric objectif yuñ miin lañu yuy wane ni kàddu yi di sone bu baax ak ni ñu ko mëna déggee, te soxla wuñu nit ku leen di déglu.
Résumé
They let engineers benchmark codecs, noise reducers, and speech-enhancement models automatically.

STOI (Xam-xam bu gàtt ci diir bu gàtt), biñ dugal ci 2010, lu moy loolu dafay wax luy xam-xam: ñaata kàddu la ki koy déglu di xam. Dafay boole enveloppe temporel yu gàtt yu wax bu sell te toppatoo ci bande fréquence yi, defar poñ yu tàmbalee ci 0 ba 1. Ñoom ñaar ñépp ay metric yu intrusive lañu (based ci royuwaay). PESQ tontu 'ndax baaxna?' STOI tontu 'ndax mën nga ko xam?' Ñoom ñépp bokk ñooy jumtukaayi jàngat yiñ jagleel ngir gëna suqali kàddu, dindi bruit ak sistemu dereverberation.

What is PESQ and STOI Speech Quality Metrics?
PESQ ak STOI ay metric objectif yuñ miin lañu yuy wane ni kàddu yi di sone bu baax ak ni ñu ko mëna déggee, te soxla wuñu nit ku leen di déglu. Dañu may ingénieur yi ñu mëna tànn ci saasi codec yi, wàññikati bruit yi ak model yiy gëna suqali kàddu.
Lu PESQ di njëkka natt?
PESQ (ITU-T P.862) dafay wax luy waaja am ci ni ñuy gisee kàddu ci balans bu niro ak MOS.
Lan la STOI njëkka wax?
STOI dafay xayma ni ñuy déggee kàddu yi, maanaam ni ñuy déggee kàddu yi, ci 0 ba 1.
PESQ ak STOI ñoom ñaar ñu ngi leen wax ni ay metric yu 'duggu'. Loolu lumuy tekki ?
Jawriñ yuy dugg dañuy méngale siñaal bi yàqu ak royuwaay bu sell ngir am poñ.
Lan mooy tolluwaayu poñ yi STOI mëna am?
STOI dafay genne valeur bu nekk ci diggante 0 ak 1, fu gëna kawe mooy gëna yomba xam.
PESQ dafay wane ni nit ñi di déggee, ban xeetu balansu fréquence perceptuel la?
PESQ dafay wane siñaal yi ci kàrtu psychoacoustic buy wane kàddu yu kawe yi ci jëfandikoo Bark-band.
