Qiyaasta tayada Hadalka PESQ iyo STOI
PESQ iyo STOI waa halbeegyada ujeeddooyinka caadiga ah ee dhaliya sida wanaagsan ee hadalka loo habeeyey iyo sida loo fahmi karo, iyada oo aan loo baahnayn dhegaystayaal bini'aadam ah.

quusid qoto dheer
PESQ (Qiimaynta Aragtida Tayada Hadalka), oo loo habeeyey sida ITU-T P.862, waxay saadaalisaa tayada hadalka ee la dareemayo, inta badan ee baaritaanka taleefanka iyo codec. Waxay is barbardhigtaa calaamad tixraac nadiif ah iyo mid hoos u dhacay waxayna soo saartaa dhibcaha MOS-sida (qiyaastii -0.5 ilaa 4.5), qaabaynta aragtida maqalka aadanaha. STOI (Aqoonsiga Ujeeddada Waqtiga Gaaban), oo la soo bandhigay 2010, beddelkeeda waxay saadaalisay garashada: inta kelmadood ee dhagaystuhu dhab ahaantii fahmi doono. Waxay isku xidhaa baqshadaha ku meel gaadhka ah ee wakhtiga gaaban ee hadalka nadiifka ah iyo habaysan ee xadhkaha soo noqnoqda, taas oo soo saarta dhibco min 0 ilaa 1. Labaduba waa cabbir (tixraac ku salaysan). PESQ waxay ku jawaabtay 'miyay fiicantahay?' halka STOI uu kaga jawaabayo 'ma fahmi kartaa?' Si wada jir ah waa aaladaha qiimaynta caadiga ah ee kobcinta hadalka, diidmada, iyo nidaamyada ka-hadalka.
Aragtida Farsamada
Labada mitirba waa faragelin: waxay la jaanqaadaan tixraac nadiif ah calaamadda la jabiyey ka hor inta aan la dhalin. Khariidadaha PESQ waxay labaduba calaamad u yihiin miisaanka qaylada cilmi nafsiga (Bark bands), waxay xisaabisaa khalkhal galnimada waqti ka dib, waxayna dib ugu celisaa qiime u eg MOS. STOI waxay hadalka u kala qaybisaa qaybo saddex-meelood meel octave ah, waxay qaadataa ~400 ms qaybo bashqad gaaban, clips oo caadi ka dhigta, ka dibna waxay xisaabisaa xidhiidhka ka dhexeeya tixraaca iyo baqshadaha hoos loo dhigay. Celcelis ahaan isku-xirnaantaas waxay soo saartaa 0-ilaa-1 dhibcaha fahamka.
Saamaynta Istiraatijiyadeed
Helitaanka iyo gaarsiinta
Waxay wanaajisaa marin u helida iyada oo loo marayo qoraal-qorid, sheeko, iyo is-dhexgalyo cod.
Qiimaha iyo miisaaniyada
Kooxaha warbaahintu waxay ku soo rari karaan codka sifaysan si degdeg ah iyagoo wata miisaaniyado yaryar.
Xawaaraha iyo miisaanka
Nidaamyada u jeedda macmiisha waxay ka baaraandegi karaan isdhexgalka hadalka si weyn.
Mustaqbalka Qiyaasaha Tayada Hadalka ee PESQ iyo STOI
Sababtoo ah PESQ iyo STOI waxay u baahan yihiin tixraac nadiif ah, cilmi-baaristu waxay u wareegaysaa kuwa aan faragelin, cabbiraadyo tixraac-la'aan ah sida DNSMOS iyo NISQA kuwaas oo keena tayada calaamadda hoos u dhacday oo keliya iyadoo la adeegsanayo shabakadaha neerfaha. Moodooyinka cusub ee barashada qoto dheer ayaa sidoo kale loo tababaray inay si toos ah u saadaaliyaan MOS bini'aadamka. Weli, PESQ iyo STOI ayaa weli ah jaangooyooyin xididaysan, iyo isbeddelka muhiimka ah ayaa ka dhigaya inay kala duwanaan karaan si loogu isticmaalo si toos ah hawlaha lumitaanka tababbarka ee shabakadaha kor u qaadida hadalka halkii ay ka ahaan lahaayeen qiimaynta dhabta ah ka dib.

Tayada Isku-dhafka Hadalka
Su'aalaha soo noqnoqda
What is PESQ and STOI Speech Quality Metrics?
PESQ iyo STOI waa halbeegyada ujeeddooyinka caadiga ah ee dhaliya sida wanaagsan ee hadalka loo habeeyey iyo sida loo fahmi karo, iyada oo aan loo baahnayn dhegaystayaal bini'aadam ah. Waxay u oggolaadeen injineerada inay si toos ah u cabbiraan codecs-ka, yaraynta qaylada, iyo moodooyinka kobcinta hadalka si toos ah.
Maxay PESQ ugu horrayn cabbirtaa?
PESQ (ITU-T P.862) waxay saadaalisay tayada hadalka ee la dareemayo ee miisaanka MOS.
Maxay STOI ugu horrayn saadaalisaa?
STOI waxay ku qiyaastay in la fahmi karo, tusaale ahaan sida hadalka loo fahmi karo, marka loo eego 0-ilaa-1.
PESQ iyo STOI labadaba waxaa lagu tilmaamay inay yihiin cabbiro 'soo jiidasho leh'. Taas macnaheedu waa maxay?
Halbeegyada faragelinta ayaa isbarbar dhigaya calaamadda la dhimay iyo tixraac nadiif ah si loo xisaabiyo dhibcaha.
Waa maxay qiyaasta qiyaasta dhibcaha ee STOI?
STOI waxay soo saartaa qiime u dhexeeya 0 iyo 1, halka sare ay ka dhigan tahay in la fahmi karo.
PESQ waxay ku daydaa maqalka bini'aadamka iyadoo adeegsanaysa nooca cabbirka inta jeer ee garashada?
Khariidadaha PESQ waxay calaamad u yihiin matalaad qaylada cilmi nafsiga ah iyadoo la adeegsanayo habaynta Bark-band.
