  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. Lan la jéego ligneer biy wax luy am ci PLP di def?

    • Dafay yokk reverb
    • Dafay soppi audio ci mbind ci saasi

    • MFCCs duñu jëfandikoo benn filtre
    • MFCC yi ci desibel kese lañu leen di nattee
    • MFCC yi deñuy soxla ay mikro
    • MFCCs yokk benn coppite cosinus ngir dindi lëkkaloog génnug bànku filtre

    • Courbe bu am doole buy méngoo ak compression bu am doole ci racine cube
    • ab royuwaayu làkk buñ tabax ci biir
    • Tekki làkku otomatik
    • Panorama stéréo
  6. Why might a deep model use log-mel features or raw waveforms instead of PLP?
    • Jëfandikoo PLP jagul yoon
    • The model can learn useful task-specific representations without every hand-designed PLP step
    • Audio raw dafay gëna ndaw saa yu nekk
    • PLP du dox ludul ci music
  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
