# Wav2Vec2-Large-XLSR-53-Russian |
|
|
|
Fine-tuned [facebook/wav2vec2-large-xlsr-53](https://huggingface.co/facebook/wav2vec2-large-xlsr-53) on Russian using the [Common Voice](https://huggingface.co/datasets/common_voice) and [CSS10](https://github.com/Kyubyong/css10). |
|
When using this model, make sure that your speech input is sampled at 16kHz. |
|
|
|
The script used for training can be found here: https://github.com/jonatasgrosman/wav2vec2-sprint |
|
|
|
## Usage |
|
|
|
The model can be used directly (without a language model) as follows: |
|
|
|
```python |
|
import torch |
|
import librosa |
|
from datasets import load_dataset |
|
from transformers import Wav2Vec2ForCTC, Wav2Vec2Processor |
|
|
|
LANG_ID = "ru" |
|
MODEL_ID = "jonatasgrosman/wav2vec2-large-xlsr-53-russian" |
|
SAMPLES = 5 |
|
|
|
test_dataset = load_dataset("common_voice", LANG_ID, split=f"test[:{SAMPLES}]") |
|
|
|
processor = Wav2Vec2Processor.from_pretrained(MODEL_ID) |
|
model = Wav2Vec2ForCTC.from_pretrained(MODEL_ID) |
|
|
|
# Preprocessing the datasets. |
|
# We need to read the audio files as arrays |
|
def speech_file_to_array_fn(batch): |
|
speech_array, sampling_rate = librosa.load(batch["path"], sr=16_000) |
|
batch["speech"] = speech_array |
|
batch["sentence"] = batch["sentence"].upper() |
|
return batch |
|
|
|
test_dataset = test_dataset.map(speech_file_to_array_fn) |
|
inputs = processor(test_dataset["speech"], 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) |
|
predicted_sentences = processor.batch_decode(predicted_ids) |
|
|
|
for i, predicted_sentence in enumerate(predicted_sentences): |
|
print("-" * 100) |
|
print("Reference:", test_dataset[i]["sentence"]) |
|
print("Prediction:", predicted_sentence) |
|
``` |

## Evaluation |
|
|
|
The model can be evaluated as follows on the Russian test data of Common Voice. |
|
|
|
```python |
|

|

|
|

|
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(DEVICE), attention_mask=inputs.attention_mask.to(DEVICE)).logits |
|
|
|
pred_ids = torch.argmax(logits, dim=-1) |
|

|

|
|
|

|
|
|
predictions = [x.upper() for x in result["pred_strings"]] |
|
references = [x.upper() for x in result["sentence"]] |
|
|
|
print(f"WER: {wer.compute(predictions=predictions, references=references, chunk_size=1000) * 100}") |
|
print(f"CER: {cer.compute(predictions=predictions, references=references, chunk_size=1000) * 100}") |
|
``` |
|
|
|
**Test Result**: |
|
|
|
In the table below I report the Word Error Rate (WER) and the Character Error Rate (CER) of the model. I ran the evaluation script described above on other models as well (on 2021-04-22). Note that the table below may show different results from those already reported, this may have been caused due to some specificity of the other evaluation scripts used. |
|
|
|
| Model | WER | CER | |
