🕌 Whisper-Small-Quran

Fine-tuned Whisper model for Quranic Recitation ASR and Verse Localization

---

📖 Overview

Whisper-Small-Quran is a fine-tuned version of OpenAI’s Whisper-Small model specialized for Quranic recitations in Arabic.
It’s part of the QV Finder project — a research system for AI-powered Quran verse transcription and retrieval.

Unlike general ASR systems, this model captures Tajweed-influenced pronunciations, regional recitation styles, and noisy real-world recordings, achieving high accuracy across both professional and normal reciters.

✨ Key Features

• 🎧 Arabic ASR tuned for Quranic Recitation
• 🕋 Verse localization via tokenization + FuzzyWuzzy two-stage string matching
• 📚 Dataset: 64 reciters · 399k verses (~2023 h total)
• 🧠 Optimized for ≤ 30 s segments, with silence-based segmentation for longer ones
• 📈 High accuracy:
  • Normal Reciters → WER 10.1 · CER 3.3
  • Professional Reciters → WER 9.9 · CER 4.1
• 🔍 100 % retrieval @ 85 % threshold with ≈ 2.5 % false positives

🧩 Intended Use

⚠️ Not a general Arabic ASR; tailored for Quranic speech and Tajweed patterns.

🧠 Model Architecture & Training

Trained on EveryAyah dataset; includes both professional and normal recitations, ensuring robustness under varied Tajweed styles and noise levels:contentReference[oaicite:1]{index=1}.

🔍 Verse Localization Pipeline

After ASR transcription:

1. Tokenization: Sliding-window n-grams (1–10 words + full verse).
2. Matching: FuzzyWuzzy ratio + Levenshtein distance.
3. Threshold: ≥ 85 % similarity → correct match.
4. Two-Stage Search: Fast coarse filter → accurate rerank → false positives ↓ to ≈ 2.5 %:contentReference[oaicite:2]{index=2}.

🚀 Quick Start

from transformers import WhisperProcessor, WhisperForConditionalGeneration
import librosa 
import torch 


model_name = "basharalrfooh/whisper-small-quran"
processor = WhisperProcessor.from_pretrained(model_name)
model = WhisperForConditionalGeneration.from_pretrained(model_name)
model.config.forced_decoder_ids = None


audio_file = "Your .wav file"

speech_array, sampling_rate = librosa.load(audio_file, sr=16000)

inputs = processor(speech_array, return_tensors="pt", sampling_rate=sampling_rate)

with torch.no_grad():
    predicted_ids = model.generate(inputs["input_features"])

# Decode token IDs to text
transcription = processor.batch_decode(predicted_ids, skip_special_tokens=True)

print(f"Transcription: {transcription}")

⚠️ Limitations

• Optimized for ≤ 30 s segments (aligned with Whisper’s training scheme).
• Domain-specific — intended for Quranic recitations only.
• Requires proper text normalization for accurate verse retrieval.
