# Sinai Voice Arabic Speech Recognition Model
# نموذج **صوت سيناء** للتعرف على الأصوات العربية الفصحى و تحويلها إلى نصوص
Fine-tuned [facebook/wav2vec2-large-xlsr-53](https://huggingface.co/facebook/wav2vec2-large-xlsr-53)
on Arabic using the [Common Voice](https://huggingface.co/datasets/common_voice)


## Usage

Please install:
- [PyTorch](https://pytorch.org/)
- `$ pip3 install jiwer lang_trans torchaudio datasets transformers`

The model can be used directly (without a language model) as follows:
```python
import torch
import torchaudio
from datasets import load_dataset
from lang_trans.arabic import buckwalter
from transformers import Wav2Vec2ForCTC, Wav2Vec2Processor
dataset = load_dataset("common_voice", "ar", split="test[:10]")
resamplers = {  # all three sampling rates exist in test split
    48000: torchaudio.transforms.Resample(48000, 16000),
    44100: torchaudio.transforms.Resample(44100, 16000),
    32000: torchaudio.transforms.Resample(32000, 16000),
}
def prepare_example(example):
    speech, sampling_rate = torchaudio.load(example["path"])
    example["speech"] = resamplers[sampling_rate](speech).squeeze().numpy()
    return example
dataset = dataset.map(prepare_example)
processor = Wav2Vec2Processor.from_pretrained("bakrianoo/sinai-voice-ar-stt")
model = Wav2Vec2ForCTC.from_pretrained("bakrianoo/sinai-voice-ar-stt").eval()
def predict(batch):
    inputs = processor(batch["speech"], sampling_rate=16000, return_tensors="pt", padding=True)
    with torch.no_grad():
        predicted = torch.argmax(model(inputs.input_values).logits, dim=-1)
    predicted[predicted == -100] = processor.tokenizer.pad_token_id  # see fine-tuning script
    batch["predicted"] = processor.tokenizer.batch_decode(predicted)
    return batch
dataset = dataset.map(predict, batched=True, batch_size=1, remove_columns=["speech"])
for reference, predicted in zip(dataset["sentence"], dataset["predicted"]):
    print("reference:", reference)
    print("predicted:", predicted)
    print("--")
```
Here's the output:
```
reference: ألديك قلم ؟
predicted: ألديك قلم
--
reference: ليست هناك مسافة على هذه الأرض أبعد من يوم أمس.
predicted: ليست نارك مسافة على هذه الأرض أبعد من يوم أمس
--
reference: إنك تكبر المشكلة.
predicted: إنك تكبر المشكلة
--
reference: يرغب أن يلتقي بك.
predicted: يرغب أن يلتقي بك
--
reference: إنهم لا يعرفون لماذا حتى.
predicted: إنهم لا يعرفون لماذا حتى
--
reference: سيسعدني مساعدتك أي وقت تحب.
predicted: سيسعدن مساعثتك أي وقد تحب
--
reference: أَحَبُّ نظريّة علمية إليّ هي أن حلقات زحل مكونة بالكامل من الأمتعة المفقودة.
predicted: أحب نظرية علمية إلي هي أن أحلقتز حلم كوينا بالكامل من الأمت عن المفقودة
--
reference: سأشتري له قلماً.
predicted: سأشتري له قلما
--
reference: أين المشكلة ؟
predicted: أين المشكل
--
reference: وَلِلَّهِ يَسْجُدُ مَا فِي السَّمَاوَاتِ وَمَا فِي الْأَرْضِ مِنْ دَابَّةٍ وَالْمَلَائِكَةُ وَهُمْ لَا يَسْتَكْبِرُونَ
predicted: ولله يسجد ما في السماوات وما في الأرض من دابة والملائكة وهم لا يستكبرون
```
## Evaluation

CLONED from [elgeish/wav2vec2-large-xlsr-53-arabic](https://huggingface.co/elgeish/wav2vec2-large-xlsr-53-arabic)

The model can be evaluated as follows on the Arabic test data of Common Voice:
```python
import jiwer
import torch
import torchaudio
from datasets import load_dataset
from lang_trans.arabic import buckwalter
from transformers import set_seed, Wav2Vec2ForCTC, Wav2Vec2Processor
set_seed(42)
test_split = load_dataset("common_voice", "ar", split="test")
resamplers = {  # all three sampling rates exist in test split
    48000: torchaudio.transforms.Resample(48000, 16000),
    44100: torchaudio.transforms.Resample(44100, 16000),
    32000: torchaudio.transforms.Resample(32000, 16000),
}
def prepare_example(example):
    speech, sampling_rate = torchaudio.load(example["path"])
    example["speech"] = resamplers[sampling_rate](speech).squeeze().numpy()
    return example
test_split = test_split.map(prepare_example)
processor = Wav2Vec2Processor.from_pretrained("bakrianoo/sinai-voice-ar-stt")
model = Wav2Vec2ForCTC.from_pretrained("bakrianoo/sinai-voice-ar-stt").to("cuda").eval()
def predict(batch):
    inputs = processor(batch["speech"], sampling_rate=16000, return_tensors="pt", padding=True)
    with torch.no_grad():
        predicted = torch.argmax(model(inputs.input_values.to("cuda")).logits, dim=-1)
    predicted[predicted == -100] = processor.tokenizer.pad_token_id  # see fine-tuning script
    batch["predicted"] = processor.batch_decode(predicted)
    return batch
test_split = test_split.map(predict, batched=True, batch_size=16, remove_columns=["speech"])
transformation = jiwer.Compose([
    # normalize some diacritics, remove punctuation, and replace Persian letters with Arabic ones
    jiwer.SubstituteRegexes({
        r'[auiFNKo\~_،؟»\?;:\-,\.؛«!"]': "", "\u06D6": "",
        r"[\|\{]": "A", "p": "h", "ک": "k", "ی": "y"}),
    # default transformation below
    jiwer.RemoveMultipleSpaces(),
    jiwer.Strip(),
    jiwer.SentencesToListOfWords(),
    jiwer.RemoveEmptyStrings(),
])
metrics = jiwer.compute_measures(
    truth=[buckwalter.trans(s) for s in test_split["sentence"]],  # Buckwalter transliteration
    hypothesis=test_split["predicted"],
    truth_transform=transformation,
    hypothesis_transform=transformation,
)
print(f"WER: {metrics['wer']:.2%}")
```
**Test Result**: 40.2%
