Question 1

+3 marksOne correct option

Consider the following code using Wav2Vec2Processor to process an audio sample:

python
import torch
from transformers import Wav2Vec2Processor


processor = Wav2Vec2Processor.from_pretrained("facebook/wav2vec2-base-960h")


sample_audio = {"array": torch.randn(12000), "sampling_rate": 16000}


inputs = processor(sample_audio["array"], sampling_rate=16000, return_tensors="pt", padding=True)


print(inputs["input_values"].shape)

What will the printed shape be?

  1. A

    (1, 16000)

  2. B

    (1, X), where X depends on the model

  3. C

    (1, 12000)

  4. D

    Error: Wav2Vec2Processor does not support PyTorch tensors

Show answer

Correct answer

  • C
