# Wav2vec2 Large 100k Voxpopuli fine-tuned with a single-speaker dataset plus Data Augmentation in Portuguese |
|
|
|
[Wav2vec2 Large 100k Voxpopuli](https://huggingface.co/facebook/wav2vec2-large-100k-voxpopuli) fine-tuned in Portuguese using a single-speaker dataset (TTS-Portuguese Corpus). |

|
|
# Use this model |
|
|
|
```python |
|
|
|
from transformers import AutoTokenizer, Wav2Vec2ForCTC |
|
|
|
tokenizer = AutoTokenizer.from_pretrained("Edresson/wav2vec2-large-100k-voxpopuli-ft-TTS-Dataset-portuguese") |
|
|
|
model = Wav2Vec2ForCTC.from_pretrained("Edresson/wav2vec2-large-100k-voxpopuli-ft-TTS-Dataset-portuguese") |

# Example test with Common Voice Dataset |
|
|
|
|
|
```python |

|
|
|
resampler = torchaudio.transforms.Resample(orig_freq=48_000, new_freq=16_000) |

|
|

|
speech, _ = torchaudio.load(batch["path"]) |
|
batch["speech"] = resampler.forward(speech.squeeze(0)).numpy() |
|
batch["sampling_rate"] = resampler.new_freq |
|
batch["sentence"] = re.sub(chars_to_ignore_regex, '', batch["sentence"]).lower().replace("’", "'") |
|
return batch |
|
``` |
|
|
|
```python |
|
ds = dataset.map(map_to_array) |
|
result = ds.map(map_to_pred, batched=True, batch_size=1, remove_columns=list(ds.features.keys())) |
