Zipformer-v3 Arabic / Quranic ASR & Forced Alignment

Attribution & Credits:
This model family is based on the state-of-the-art Zipformer2-CTC architecture developed by Quran-Lab (Quran-Lab/zipformer_p-arabic-v3). All original training, phonetization, and dataset curation credits belong to the Quran-Lab team and the authors of quran-transcript.

Quantization & Model Variants Table

This repository hosts ONNX quantized and precision-optimized variants designed for edge, CPU, and high-throughput GPU forced-alignment pipelines:

Benchmark Highlights (Surah Al-Kahf 18 & Surah Al-Baqarah 2)

Evaluated across continuous full-surah recitations on NVIDIA Tesla T4 GPU:

Parity: 0.00 ms mean delta against FP32 reference alignment.
Throughput: Aligns full 24.8-minute continuous audio (1,584 words) in 6.69 seconds flat.
Entire 30-Juz Quran (~25 hours audio): Full word-level forced-alignment and repeat-detection in ~6.3 minutes.

Usage with `quran-forced-align`

Install and align with zero configuration:

# Installs and runs with automatic GPU/CPU detection and auto-model caching:
pip install quran-forced-align

# Single Surah alignment (JSON + SRT):
quran-forced-align --surah 66 --audio audio/066_basit.mp3 --out output/066.json

Python Streaming ONNX Inference

import onnxruntime as ort
import numpy as np

# Load FP16 model on CUDA Execution Provider:
opts = ort.SessionOptions()
opts.graph_optimization_level = ort.GraphOptimizationLevel.ORT_ENABLE_ALL

session = ort.InferenceSession(
    "zipformer_p_arabic_v3.1.fp16.onnx",
    sess_options=opts,
    providers=[('CUDAExecutionProvider', {'device_id': 0, 'enable_cuda_graph': True}), 'CPUExecutionProvider']
)

Achieves **0.029% WER** on EveryAyah. ## How the Model Works ``` Audio (16 kHz mono) → Log-Mel Spectrogram [80 bands, 10 ms frames] → FastConformer Encoder (114.6M params, 8× temporal subsampling) → Linear Projection → LogSoftmax → [T_out × 1025] log-probs → CTC Greedy Decode (argmax + blank collapse) → token IDs ``` **Key details:** - **Encoder**: FastConformer Large — convolution-augmented Transformer. Each output frame covers 80 ms of audio. - **CTC Head**: Linear projection + LogSoftmax over 1025 classes (1024 SentencePiece BPE tokens + 1 blank). - **Decoder**: CTC greedy decoding — frame-independent, no language model, preserves mispronunciations. - **Tokenizer**: SentencePiece BPE, vocabulary size 1024, trained on Quranic Arabic with Tajweed diacritics. - **Fine-tuned** from NVIDIA's `stt_en_fastconformer_hybrid_large_pc` on EveryAyah + tlog. ## Files ### Unified Models | Path | Description | |------|-------------| | `onnx/model_fp32.onnx` | CTC-only ONNX, float32 (437 MB) | | `onnx/model_fp16.onnx` | CTC-only ONNX, float16 (219 MB) | | `onnx/model_int8.onnx` | CTC-only ONNX, int8 quantized (167 MB) | | `onnx/model_int8.ort` | CTC-only ORT format, optimized for runtime (175 MB) | | `onnx/model_quantized_int8.ort` | Unified Q8 model optimized for web-browser runtime (132 MB) | | `onnx/model_with_encoder.q8.ort` | Unified Q8 model with encoder outputs exposed (132 MB) | ### Split Streaming Models (Method 2b) | Path | Description | |------|-------------| | `onnx/fc_subsampler.ort` | Subsampler module of the split FastConformer Q8 model (1.6 MB) | | `onnx/fc_subsampler_fp32.ort` | Subsampler module of the split FastConformer model in FP32 precision (5.9 MB) | | `onnx/fc_context_encoder.ort` | Context...
