2. Waa maxay cabirka mel loo qorsheeyay inuu matalo?
   • Uniform spacing of all frequencies in hertz
   • A nonlinear frequency spacing related to how listeners perceive pitch differences
   • Only signal loudness
   • Removal of all high-frequency content

6. In the Tacotron 2 pipeline, what does the vocoder do after mel prediction?
   • Turns audio into subtitles
   • Converts the predicted mel spectrogram into waveform audio
   • Sets a video frame rate
   • Chooses the number of mel bands
7. What does hop_length specify in a mel-spectrogram computation?
   • The number of microphones in the recording
   • The count of mel bands
   • The number of audio samples between successive analysis frames
   • The length of the generated transcript
8. What does fmax set in a mel filter bank?
   • The number of video frames
   • The length of the output transcript
   • The number of microphones in the recording
   • The highest frequency included in the mel bands
