| # Wav2Vec2-Large-XLSR-53-{language} #TODO: replace language with your {language}, *e.g.* French | |
| Fine-tuned [facebook/wav2vec2-large-xlsr-53](https://huggingface.co/facebook/wav2vec2-large-xlsr-53) on {language} using the [Common Voice](https://huggingface.co/datasets/common_voice), ... and ... dataset{s}. #TODO: replace {language} with your language, *e.g.* French and eventually add more datasets that were used and eventually remove common voice if model was not trained on common voice | |
| 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 torch | |
| import torchaudio | |
| from datasets import load_dataset | |
| from transformers import Wav2Vec2ForCTC, Wav2Vec2Processor | |
| test_dataset = load_dataset("common_voice", "{lang_id}", split="test[:2%]") #TODO: replace {lang_id} in your language code here. Make sure the code is one of the *ISO codes* of [this](https://huggingface.co/languages) site. | |
| processor = Wav2Vec2Processor.from_pretrained("{model_id}") #TODO: replace {model_id} with your model id. The model id consists of {your_username}/{your_modelname}, *e.g.* `elgeish/wav2vec2-large-xlsr-53-arabic` | |
| model = Wav2Vec2ForCTC.from_pretrained("{model_id}") #TODO: replace {model_id} with your model id. The model id consists of {your_username}/{your_modelname}, *e.g.* `elgeish/wav2vec2-large-xlsr-53-arabic` | |
| resampler = torchaudio.transforms.Resample(48_000, 16_000) | |
| # Preprocessing the datasets. | |
| # We need to read the aduio files as arrays | |
| 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) | |
| inputs = processor(test_dataset["speech"][:2], sampling_rate=16_000, return_tensors="pt", padding=True) | |
| with torch.no_grad(): | |
| logits = model(inputs.input_values, attention_mask=inputs.attention_mask).logits | |
| predicted_ids = torch.argmax(logits, dim=-1) | |
| print("Prediction:", processor.batch_decode(predicted_ids)) | |
| print("Reference:", test_dataset["sentence"][:2]) | |
| ``` | |
| ## Evaluation | |
| The model can be evaluated as follows on the {language} test data of Common Voice. # TODO: replace #TODO: replace language with your {language}, *e.g.* French | |
| ```python | |
| import torch | |
| import torchaudio | |
| from datasets import load_dataset, load_metric | |

| model.to("cuda") | |
| chars_to_ignore_regex = '[\,\?\.\!\-\;\:\"\“]' # TODO: adapt this list to include all special characters you removed from the data | |
| resampler = torchaudio.transforms.Resample(48_000, 16_000) | |
| # Preprocessing the datasets. | |
| # We need to read the aduio files as arrays | |
| def speech_file_to_array_fn(batch): | |
| batch["sentence"] = re.sub(chars_to_ignore_regex, '', batch["sentence"]).lower() | |
| 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) | |
| # Preprocessing the datasets. | |
| # We need to read the aduio files as arrays | |
| def evaluate(batch): | |
| inputs = processor(batch["speech"], sampling_rate=16_000, return_tensors="pt", padding=True) | |
| with torch.no_grad(): | |
| logits = model(inputs.input_values.to("cuda"), attention_mask=inputs.attention_mask.to("cuda")).logits | |
| pred_ids = torch.argmax(logits, dim=-1) | |
| batch["pred_strings"] = processor.batch_decode(pred_ids) | |
| return batch | |
| result = test_dataset.map(evaluate, batched=True, batch_size=8) | |
| print("WER: {:2f}".format(100 * wer.compute(predictions=result["pred_strings"], references=result["sentence"]))) | |
| ``` | |
| **Test Result**: XX.XX % # TODO: write output of print here. IMPORTANT: Please remember to also replace {wer_result_on_test} at the top of with this value here. tags. | |
| ## Training | |
| The Common Voice `train`, `validation`, and ... datasets were used for training as well as ... and ... # TODO: adapt to state all the datasets that were used for training. | |
| The script used for training can be found [here](...) # TODO: fill in a link to your training script here. If you trained your model in a colab, simply fill in the link here. If you trained the model locally, it would be great if you could upload the training script on github and paste the link here. |
