Jawaabaha iyo sharraxaadaha waxay soo baxayaan markaad qaadanayso kediska.

  1. Why do speech filterbanks use mel- or Bark-spaced bands instead of uniformly spaced hertz?
    • The scales allocate finer frequency spacing at low frequencies and coarser spacing at high frequencies, approximating aspects of hearing
    • They make files smaller only
    • They remove all background noise
    • They guarantee perfect speech recognition
  2. Maxay fulisaa tallaabada saadaasha tooska ah ee PLP?
    • Waxay kordhisaa mugga
    • Waxay ku habboon tahay baqshad siman oo muuqaal ah oo qabanaysa qaabka dhawaaqa
    • Waxay ku daraysaa tix-raac
    • Waxay si toos ah ugu beddeshaa maqalka qoraalka
  3. Qaabkee noocee ah ayaa ah wax gelinta ugu badan ee moodooyinka aqoonsiga hadalka qoto dheer ee casriga ah?
    • Faylasha MIDI ceeriin
    • Qoraallada gacanta lagu qoray
    • Log-mel filterbank sifooyinka
    • JPEG spectrograms
  4. Sidee MMFC-yadu uga duwan yihiin sifooyinka bangiga ee log-mel filterbank?
    • MVCC-yadu gabi ahaanba ma isticmaalaan filtarrada
    • MVCC-yada waxa lagu cabbiraa decibels kaliya
    • MCC-yadu waxay u baahan yihiin qalab makarafoon
    • MVCC-yadu waxay ku daraan beddelka cosine si ay u qurxiyaan wax soo saarka bangiga filter
  5. Waa maxay shay la fahmi karo oo ay PLP ku jirto oo aanay ku jirin bangiyada filtarrada aasaasiga ah?
    • Qalooca qaylada siman iyo cube-root xoojinta xoojinta
    • Qaab luuqad ku dhisan
    • Turjumaad toos ah
    • Isteeriyo gariir
  6. Why might a deep model use log-mel features or raw waveforms instead of PLP?
    • PLP waa sharci darro in la isticmaalo
    • The model can learn useful task-specific representations without every hand-designed PLP step
    • Codka ceeriin had iyo jeer waa ka yar yahay
    • PLP waxay u shaqeysaa muusigga oo kaliya
  7. What is a typical log-mel filterbank feature for one speech frame?
    • A word-level translation
    • A single pitch label for the whole recording
    • The logarithm of spectral energy pooled through a mel-spaced filter
    • A pixel color from a spectrogram image
  8. Which order best describes the main PLP processing steps?
    • Translation, tokenization, and decoding
    • Stereo panning, reverb, and compression
    • Image segmentation followed by color correction
    • Critical-band analysis, equal-loudness weighting, loudness compression, then linear prediction
