# Wav2Vec2-Large-XLSR-53-Hindi-Marathi |
|
Fine-tuned facebook/wav2vec2-large-xlsr-53 on Hindi and Marathi using the OpenSLR SLR64 datasets. When using this model, make sure that your speech input is sampled at 16kHz. |
|
|
|
## Installation |
|
```bash |
|
pip install git+https://github.com/huggingface/transformers.git datasets librosa torch==1.7.0 torchaudio==0.7.0 jiwer |
|
``` |
|
|
|
## Eval dataset: |
|
```bash |
|
wget https://www.openslr.org/resources/103/Marathi_test.zip -P data/marathi |
|
unzip -P "K3[2?do9" data/marathi/Marathi_test.zip -d data/marathi/. |
|
tar -xzf data/marathi/Marathi_test.tar.gz -C data/marathi/. |
|
wget https://www.openslr.org/resources/103/Hindi_test.zip -P data/hindi |
|
unzip -P "w9I2{3B*" data/hindi/Hindi_test.zip -d data/hindi/. |
|
tar -xzf data/hindi/Hindi_test.tar.gz -C data/hindi/. |
|
wget -O test.csv 'https://filebin.net/snrz6bt13usv8w2e/test_large.csv?t=ps3n99ho' |
|
#If download does not work, paste this link in browser: https://filebin.net/snrz6bt13usv8w2e/test_large.csv |
|
``` |
|
## Usage |
|
The model can be used directly (without a language model) as follows, assuming you have a dataset with Marathi text and path fields: |
|
|
|
|
|
|
|
```python |
|
import torch |
|
import torchaudio |
|
import librosa |
|
from datasets import load_dataset |
|
from transformers import Wav2Vec2ForCTC, Wav2Vec2Processor |
|
|
|
from datasets import load_metric, Dataset |
|
from transformers import Wav2Vec2Processor, Wav2Vec2ForCTC |
|
|
|
wer = load_metric("wer") |
|
processor = Wav2Vec2Processor.from_pretrained('tanmaylaud/wav2vec2-large-xlsr-hindi-marathi') |
|
model = Wav2Vec2ForCTC.from_pretrained('tanmaylaud/wav2vec2-large-xlsr-hindi-marathi').to("cuda") |
|
|
|

|

|

|

|
batch["target_text"] = batch["sentence"] |
|
batch["speech"] = librosa.resample(np.asarray(batch["speech"]), sampling_rate, 16_000) |
|
batch["sampling_rate"] = 16_000 |
|
return batch |
|
|
|

|

|
|
|

|
logits = model(inputs.input_values, attention_mask=inputs.attention_mask).logits |
|
|
|
predicted_ids = torch.argmax(logits, dim=-1) |
|
|
|
