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

**wav2vec2-large-xlsr-53** fine-tuned on 8.5 hours of labeled Darija Audios

I have also added 3 phonetic units to this model ڭ, ڤ and پ. For example: ڭال , ڤيديو , پودكاست

## Usage

The model can be used directly (without a language model) 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)
```

Here's the output: ڭالت ليا هاد السيد هادا ما كاينش بحالو 

## Evaluation & Previous works

-v2 (fine-tuned on 8.5 hours of audio + replaced أ and ى and إ with ا as it creates a lot of problems + tried to standardize the Moroccan Darija)

**Wer**: 44.30

**Training Loss**: 12.99

**Validation Loss**: 36.93

#############################################################

-v1 (fine-tuned on 6 hours of audio)

**Wer**: 49.68

**Training Loss**: 9.88

**Validation Loss**: 45.24

## Future Work

I am currently working on improving this model. The new model will be available soon.
