Jawaabaha iyo sharraxaadaha waxay soo baxayaan markaad qaadanayso kediska.

  1. Dhibaato noocee ah ayuu baajinta dhawaaqa dhawaaqa ugu horrayn xalliyaa?
    • Joojinta dhawaqa hadlaaya in makarafoonku qaado oo dib loogu celiyo dhamaadka fog
    • Cadaadiska faylalka maqalka ah si loo badbaadiyo baaxadda baaxadda
    • U tarjumaadda hadalka luqad kale
    • Kor u qaadida mugga kuwa ku hadla aamusnaanta
  2. Calaamadee 'Tixraaca' nidaamka AEC wuxuu ku tiirsan yahay saadaalinta dhawaaqa?
    • Gelida makarafoonka ku hadlaaya dhammaadka dhow
    • Digniinta-dhamaadka fog oo laga daminayo afhayeenka
    • Nashqada qolka horay loo duubay
    • Heerka dhawaaqa asalka
  3. Xaaladdee ayaa caan ku ah ku adag AEC oo sababi karta shaandhada la qabsiga inay si xun u dhaqanto?
    • Aamusnaanta dhamaystiran labada daraf
    • Qof keli ah oo si tartiib ah u hadlaya
    • Laba-hadal, marka labada dhinac wada hadlaan isku mar
    • Muusigga oo aan cidna la hadlin
  4. Waa maxay shaandhada la-qabsiga ee AEC-da caadiga ah dhab ahaantii waxay isku daydaa inay qiyaasto?
    • Codka shucuurta leh ee hadlaya
    • Awoodda calaamadda Wi-Fi
    • Codka riixitaanka ayaa la isticmaalayaa
    • Jidka dhawaaqa (jawaabta dareenka leh) laga bilaabo afhayeenka ilaa makarafoonka qolka dhexdiisa
  5. Waa maxay sababta shabakadaha neerfaha si sii kordheysa loogu daro miirayaasha AEC ee caadiga ah?
    • Si loo xakameeyo qallooca aan tooska ahayn iyo dhawaaq-celinta hadhaaga ah ee filtarrada tooska ahi seegaan
    • Si aad wicitaanada uga dhigto mid qaali ah
    • Si aad u bedesho qalabka makarafoonka
    • Si loo yareeyo habaynta saxnaanta
  6. Algorithmmeekee la qabsiga la qabsiga ah ee sida caadiga ah xiriir la leh joojinta echo-dhaqameed?
    • Sirta RSA
    • Afar-geesood ee ugu hooseeya ee la caadaystay (NLMS)
    • JPEG cadaadis
    • Algorithm ee Dijkstra
  7. Why must an adaptive echo-path filter keep updating during a call?
    • The far-end reference changes its language every second
    • The microphone stops recording whenever a door opens
    • Room acoustics can change when people or objects move, changing the path from speaker to microphone
    • A fixed filter automatically learns new room conditions without updates
  8. What kinds of recordings are included in Microsoft's AEC Challenge datasets?
    • Only music recorded in anechoic chambers
    • Only far-end speech with no microphone signal
    • Only speech with no echo or near-end speaker
    • Single-talk and double-talk recordings from real devices and speakers, plus synthetic data
