Question 4

+3 marksOne correct option

In an ASR model like Wav2Vec2-CTC, the final linear layer outputs a tensor of logits. What does this tensor represent?

  1. A

    The final transcribed text string.

  2. B

    A probability distribution over potential speaker identities.

  3. C

    Raw, unnormalized scores for each token in the vocabulary (including the blank token) for each time step.

  4. D

    The mel-spectrogram of the input audio, compressed by the encoder.
