Majibu na maelezo huonekana unapojibu maswali.

  1. What information is a speaker-recognition x-vector designed to emphasize?
    • Only the exact words spoken as text
    • Only the recording's file format
    • A guaranteed identity proof unaffected by recording conditions
    • Speaker-related characteristics rather than a transcript of the utterance
  2. Ni safu gani inayogeuza matamshi ya urefu tofauti kuwa vekta moja ya urefu usiobadilika katika mtandao wa x-vekta?
    • Kichujio cha kubadilisha picha
    • Safu ya kukusanya takwimu inayokokotoa maana na mkengeuko wa kawaida katika muda wote
    • Safu ya kuacha
    • Upeo laini wa mwisho unaotumika kama upachikaji wenyewe
  3. Ni aina gani ya mtandao wa neural hutumika jadi kutoa x-vekta?
    • Mtandao wa maadui unaozalisha
    • Mkusanyiko wa mti wa maamuzi
    • Mtandao wa Neural wa Kuchelewa kwa Wakati (TDNN)
    • Urejeshaji wa mstari wazi
  4. Je, vekta mbili za x kawaida hulinganishwa vipi na kuamua ikiwa zinatoka kwa spika moja?
    • Kwa kufanana kwa cosine au PLDA backend
    • Kwa kuhesabu maneno yanayolingana
    • Kwa kulinganisha saizi za faili
    • Kwa kuangalia kiwango cha sampuli ya sauti
  5. Which established representation supplied comparison baselines in the 2018 x-vector speaker-recognition study?
    • A visual image-token embedding
    • A text-only word-count vector
    • i-vekta
    • An audio file-size histogram
  6. Je, ni usanifu upi mpya zaidi unaoboreshwa kwenye x-vekta ya kawaida kwa umakini wa kituo na mkusanyo makini wa takwimu?
    • ResNet-50 kwa picha
    • GPT-2
    • YOLO
    • ECAPA-TDNN
  7. Why is the classic x-vector extracted from a hidden segment-level layer rather than used as the final training-speaker softmax output?
    • The hidden representation can be compared as an embedding instead of being limited to probabilities for the training speaker labels
    • The hidden layer contains the recording's text transcript
    • Softmax probabilities are the only place where acoustic information exists
    • Hidden layers cannot process an unseen recording
  8. What does a time-delay layer contribute before statistics pooling in an x-vector extractor?
    • It stores only a single final filename
    • It combines information from neighboring acoustic frames, building temporal context
    • It assigns a new random speaker label to every frame
    • It removes all time information before any acoustic processing
