# Disclaimer and Requirements

This model is a clone of [**jonatasgrosman/wav2vec2-large-xlsr-53-english**](https://huggingface.co/jonatasgrosman/wav2vec2-large-xlsr-53-english) compressed using ZipNN. Compressed losslessly to 88% its original size, ZipNN saved ~0.2GB in storage and potentially ~4PB in data transfer **monthly**.

### Requirement

In order to use the model, ZipNN is necessary:
```bash
pip install zipnn
```
### Use This Model
```python
# Use a pipeline as a high-level helper
from transformers import pipeline
from zipnn import zipnn_hf

zipnn_hf()


pipe = pipeline("automatic-speech-recognition", model="royleibov/wav2vec2-large-xlsr-53-english-ZipNN-Compressed")
```
```python
# Load model directly
from transformers import AutoProcessor, AutoModelForCTC
from zipnn import zipnn_hf

zipnn_hf()

processor = AutoProcessor.from_pretrained("royleibov/wav2vec2-large-xlsr-53-english-ZipNN-Compressed")
model = AutoModelForCTC.from_pretrained("royleibov/wav2vec2-large-xlsr-53-english-ZipNN-Compressed")
```
### ZipNN
ZipNN also allows you to seemlessly save local disk space in your cache after the model is downloaded.

To compress the cached model, simply run:
```bash
python zipnn_compress_path.py safetensors --model royleibov/wav2vec2-large-xlsr-53-english-ZipNN-Compressed --hf_cache
```

The model will be decompressed automatically and safely as long as `zipnn_hf()` is added at the top of the file like in the [example above](#use-this-model).

To decompress manualy, simply run:
```bash
python zipnn_decompress_path.py --model royleibov/wav2vec2-large-xlsr-53-english-ZipNN-Compressed --hf_cache
```

# Fine-tuned XLSR-53 large model for speech recognition in English

Fine-tuned [facebook/wav2vec2-large-xlsr-53](https://huggingface.co/facebook/wav2vec2-large-xlsr-53) on English using the train and validation splits of [Common Voice 6.1](https://huggingface.co/datasets/common_voice).
When using this model, make sure that your speech input is sampled at 16kHz.

This model has been fine-tuned thanks to the GPU credits generously given by the [OVHcloud](https://www.ovhcloud.com/en/public-cloud/ai-training/) :)

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...

Using the [HuggingSound](https://github.com/jonatasgrosman/huggingsound) library:

```python
from huggingsound import SpeechRecognitionModel
from zipnn import zipnn_hf

zipnn_hf()

model = SpeechRecognitionModel("royleibov/wav2vec2-large-xlsr-53-english-ZipNN-Compressed")
audio_paths = ["/path/to/file.mp3", "/path/to/another_file.wav"]

transcriptions = model.transcribe(audio_paths)
```

Writing your own inference script:

```python
import torch
import librosa
from datasets import load_dataset
from transformers import Wav2Vec2ForCTC, Wav2Vec2Processor
from zipnn import zipnn_hf

zipnn_hf()

LANG_ID = "en"
MODEL_ID = "royleibov/wav2vec2-large-xlsr-53-english-ZipNN-Compressed"
SAMPLES = 10

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)
```
