  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. Ndeipi dhizaini inoshandura kutaura-kureba kunoshanduka kuita imwechete yakagadzika-kureba vheta mune x-vector network?
    • A convolutional image filter
    • A statistics pooling layer inokombuta zvinoreva uye mwero kutsauka panguva
    • A dropout layer
    • Yekupedzisira softmax inoshandiswa sekuzvimisikidza pachayo
  3. Ndeupi rudzi rweneural network inowanzoshandiswa kubvisa x-vectors?
    • A generative adversarial network
    • Muti wechisarudzo ensemble
    • A Time-Delay Neural Network (TDNN)
    • A plain linear regression
  4. Ko maviri x-vector anowanzo kuenzaniswa sei kusarudza kana achibva kumutauri mumwe chete?
    • Nekufanana kwecosine kana PLDA backend
    • Nekuverenga mazwi anoenderana
    • Nokuenzanisa masaizi efaira
    • Nekutarisa redhiyo sampuli mwero
  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-vectors
    • An audio file-size histogram
  6. Ndechipi chivakwa chitsva chinovandudza pane yekare x-vector ine chiteshi kutarisisa uye nekutarisa manhamba?
    • ResNet-50 yemifananidzo
    • 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
