Unable to load audio_features from common_voice dataset
## Describe the bug
I am not able to load audio features from common_voice dataset

## Steps to reproduce the bug

```
from datasets import load_dataset
import torchaudio

test_dataset = load_dataset("common_voice", "hi", split="test[:2%]")
resampler = torchaudio.transforms.Resample(48_000, 16_000)

def speech_file_to_array_fn(batch):
      speech_array, sampling_rate = torchaudio.load(batch["path"])
      batch["speech"] = resampler(speech_array).squeeze().numpy()
      return batch
test_dataset = test_dataset.map(speech_file_to_array_fn)
```
## Expected results

This piece of code should return test_dataset after loading audio features.

## Actual results
