Majibu na maelezo huonekana unapojibu maswali.

  1. Je, Alama ya Maoni ya Maana ya 5 inawakilisha nini kwenye mizani ya kawaida?
    • Ubora bora
    • Ubora mbaya
    • Ubora wa haki
    • Sauti ambayo haijakadiriwa
  2. Why do MOS studies collect ratings from multiple listeners?
    • Ili kufanya mtihani kuwa nafuu
    • To estimate the average opinion and variability across listeners
    • Kwa sababu mtu mmoja hawezi kusikia sauti
    • Ili kuongeza bitrate
  3. Ni shirika gani lililosanifisha mbinu asili ya MOS kwa ubora wa sauti?
    • FDA
    • NASA
    • ITU (katika Pendekezo P.800)
    • Sehemu ya W3C
  4. Ni kizuizi gani muhimu cha kulinganisha maadili ya MOS kutoka kwa masomo mawili tofauti?
    • MOS inaweza kupimwa mara moja pekee
    • MOS inahitaji maunzi maalum ambayo haipo
    • MOS hufanya kazi kwa muziki pekee, sio hotuba
    • Alama zimeunganishwa kwa klipu na maagizo ya kila kipindi, kwa hivyo hazilinganishwi moja kwa moja
  5. Watabiri wa MOS otomatiki kama DNSMOS au UTMOS hutatua shida gani?
    • Wanakadiria alama za ubora bila majaribio ya polepole na ya gharama ya usikilizaji wa binadamu
    • Wanaongeza sauti zaidi
    • Wanabadilisha hitaji la maikrofoni
    • Wanakandamiza faili za sauti
  6. What limitation can affect MOS comparisons among systems with very high ratings?
    • The scale changes from 1–5 to 1–10 automatically
    • Ceiling effects can compress differences near the top of the bounded scale
    • Wasikilizaji wanakataa kukadiria sauti ya AI
    • MOS only measures volume
  7. In Comparison Category Rating (CCR), what do listeners judge?
    • Each sample’s absolute quality with no comparison
    • The number of words in a transcript
    • The quality difference between compared samples
    • The bitrate of the audio file
  8. What generalization limitation did the VoiceMOS Challenge 2022 report for MOS predictors?
    • They cannot process speech samples
    • They only output integer scores from 1 to 5
    • They work only when no human ratings exist
    • Predicting ratings for unseen speakers, listeners, or systems can be difficult
