# Wav2Vec2-Base-TIMIT |
|
|
|
Fine-tuned [facebook/wav2vec2-base](https://huggingface.co/facebook/wav2vec2-base) |
|
on the [timit_asr dataset](https://huggingface.co/datasets/timit_asr). |
|
When using this model, make sure that your speech input is sampled at 16kHz. |
|
|
|
## Usage |
|
|
|
The model can be used directly (without a language model) as follows: |
|
|
|
```python |
|
import soundfile as sf |
|
import torch |
|
from datasets import load_dataset |
|
from transformers import Wav2Vec2ForCTC, Wav2Vec2Processor |
|
|
|
model_name = "elgeish/wav2vec2-base-timit-asr" |
|
processor = Wav2Vec2Processor.from_pretrained(model_name) |
|
model = Wav2Vec2ForCTC.from_pretrained(model_name) |
|
model.eval() |
|
|
|
dataset = load_dataset("timit_asr", split="test").shuffle().select(range(10)) |
|
char_translations = str.maketrans({"-": " ", ",": "", ".": "", "?": ""}) |
|
|
|
def prepare_example(example): |
|
example["speech"], _ = sf.read(example["file"]) |
|
example["text"] = example["text"].translate(char_translations) |
|
example["text"] = " ".join(example["text"].split()) # clean up whitespaces |
|
example["text"] = example["text"].lower() |
|
return example |
|
|
|
dataset = dataset.map(prepare_example, remove_columns=["file"]) |
|
inputs = processor(dataset["speech"], sampling_rate=16000, return_tensors="pt", padding="longest") |
|
|
|
with torch.no_grad(): |
|
predicted_ids = torch.argmax(model(inputs.input_values).logits, dim=-1) |
|
predicted_ids[predicted_ids == -100] = processor.tokenizer.pad_token_id # see fine-tuning script |
|
predicted_transcripts = processor.tokenizer.batch_decode(predicted_ids) |
|
|
|
for reference, predicted in zip(dataset["text"], predicted_transcripts): |
|
print("reference:", reference) |
|
print("predicted:", predicted) |
|
print("--") |
|
``` |
|
|
|
Here's the output: |
|
|
|
``` |
|
reference: she had your dark suit in greasy wash water all year |
|
predicted: she had your dark suit in greasy wash water all year |
|
-- |
|

predicted: don't do chawly's tirty dishes |
|

|
reference: only those story tellers will remain who can imitate the style of the virtuous |
|
predicted: only those story tillaers will remain who can imvitate the style the virtuous |
|
``` |
