Hearing-Aid Speech Quality Index

Indangantego yo Kumva-Imfashanyo Yerekana Indangagaciro ( HASQI ) ni igipimo cy'ubwiza bw'amajwi cyashyizweho mu rwego rwo gusuzuma ubwiza bw'ijijwi ry'abantu bafite icyuma cy'amatwi ,.   Byerekanwe kandi ko bishobora gupima ubuziranenge bw'amajwi ku majwi atavuga ndetse n'ababumva nta kubura kumva . 

 Amavu n'amavuko 
Mugihe imyumvire yubwiza bwamajwi ishobora gupimwa hifashishijwe ibipimo byo gushishoza, ikizamini gitwara igihe kinini gukora. Kubera iyo mpamvu, ibipimo byinshi byateguwe kugira ngo amajwi asuzumwe bitabaye ngombwa ko abantu bumva. Ingero zisanzwe ziva kuri terefone zirimo PESQ, POLQA, PEVQ na PEAQ . HASQI yashyizweho bwa mbere na Kates na Arehart kugira ngo basuzume uburyo imyitwarire mibi yinjizwa n'ibyuma by'amatwi igabanya ubwiza bw'amajwi Kates, James; Arehart, Kathryn (2010).

S2CID 2722337. yagerageje kuvuga imvugo itandukanye na dataset yakoreshejwe mugutezimbere HASQI kandi yerekana ko indangagaciro rusange neza kubayumva nta gutakaza kumva hamwe nibikorwa bigereranywa na PESQ.

 Uburyo 
HASQI hamwe nisubiramo ryayo 2014 n'uburyo bubiri bwarangiye busaba ibyerekezo bisukuye hamwe n'ibimenyetso bitesha agaciro kugirango bisuzumwe. Iki gipimo kigerageza kugaragaza ingaruka z'urusaku, kwivanga kudakwiye kw'amajwi (nonlinear distortion), kuyungura ku murongo (linear filtering) n'impinduka z'umurongo w'amajwi (spectral changes) binyuze mu kubara itandukaniro cyangwa isano hagati y'ingenzi mu biranga amajwi.Ibi bikorwa mugusuzuma ibahasha yerekana ibimenyetso byigihe gito kugirango hamenyekane iyangirika ryatewe nurusaku no kuyungurura umurongo, hamwe namabahasha yigihe kirekire kugirango agereranye ingaruka zo kuyungurura umurongo. Verisiyo ya 2 ya HASQI ikubiyemo icyitegererezo cyo gufata ibintu bimwe na bimwe bya sisitemu yo kumva ya periferique kubantu basanzwe kandi bafite ubumuga bwo kutumva.

Ibi bifasha ubwiza bwamajwi gusuzumwa uhereye kubimenyetso byangiritse gusa udakeneye ibisobanuro bisukuye. Kendrick, Paul; Li, Francis; Fazenda, Bruno; Jackson, Iain; Cox, Trevor (2015).
