# Wav2Vec2-Large-XLSR-53-Moroccan-Darija

**wav2vec2-large-xlsr-53** fine-tuned on 29 hours (29 people) of labeled Darija Audios.

# Old model vs new model

<u>Old Model:</u>
- The model contains numerous incorrect transcriptions as input
- Multiple transcribers.
- The audio database is not organized (by gender, age, regions ..).
- Wrong wer rate

<u>New Model:</u>
- Transcriptions are now performed by a single individual.
- Each hour of audio is pronounced by a different person.
- Fine-tuning is ongoing 24/7 to enhance accuracy, and we are consistently adding more data to the model every day.
- Audio database is more organized
- True Wer rate

## Usage

The model can be used directly as follows:

```python
import librosa
import torch
from transformers import Wav2Vec2CTCTokenizer, Wav2Vec2ForCTC, Wav2Vec2Processor, TrainingArguments, Wav2Vec2FeatureExtractor, Trainer

tokenizer = Wav2Vec2CTCTokenizer("./vocab.json", unk_token="[UNK]", pad_token="[PAD]", word_delimiter_token="|")
processor = Wav2Vec2Processor.from_pretrained('boumehdi/wav2vec2-large-xlsr-moroccan-darija', tokenizer=tokenizer)
model=Wav2Vec2ForCTC.from_pretrained('boumehdi/wav2vec2-large-xlsr-moroccan-darija')


# load the audio data (use your own wav file here!)
input_audio, sr = librosa.load('file.wav', sr=16000)

# tokenize
input_values = processor(input_audio, return_tensors="pt", padding=True).input_values

# retrieve logits
logits = model(input_values).logits

tokens = torch.argmax(logits, axis=-1)

# decode using n-gram
transcription = tokenizer.batch_decode(tokens)

# print the output
print(transcription)
```

Output: قالت ليا هاد السيد هادا ما كاينش بحالو
