# 🐣🎙️ Shenava Rizeh-Pizeh v1.0 · شنوا ریزه‌پیزه

The smallest Shenava-1 Persian ASR model: a 6.9M-parameter FastConformer distilled through the Koochik → Rizeh → Rizeh-Pizeh cascade. This repository contains the FP32 NeMo source checkpoint for evaluation, fine-tuning, and export.

## 🧠 Model contract

- Audio: mono, 16 kHz Persian speech.
- Encoder: `d_model=144`, 12 layers, 8x subsampling.
- Contexts: `[70,13]`, `[70,6]`, `[70,1]`, and `[70,0]`.
- Deployed head: CTC.
- Tokenizer: ve_tok_v4, SentencePiece BPE-1024 plus blank.
- Output: Persian text; use display-layer ITN when Persian digits are required.

The release reported real-time FP32 tract inference on a 2015 Cortex-A7 (RTF about 0.91). Treat that as a release-specific device measurement, not a universal latency guarantee.

## 📊 Published evaluation

Decoded with context `[70,13]` and the double-benchmark ITN/Persian-digit normalization convention.

| Set | WER | CER |
|---|---:|---:|
| visualears-golden-6669 | 24.55% | 8.89% |
| FLEURS-fa | 26.95% | 10.22% |

## 🚀 Load with NeMo

```python
from nemo.collections.asr.models import ASRModel

model = ASRModel.restore_from("shenava-rizeh-pizeh-v1.0.nemo")
print(model.transcribe(["speech.wav"])[0].text)
```

Choose this model when footprint and low-end CPU viability matter more than the accuracy available from the 32M Rizeh or 114M Koochik checkpoints.

## 🇮🇷 خلاصهٔ فارسی

«شنوا ریزه‌پیزه» کوچک‌ترین مدل خانواده است: ۶٫۹ میلیون پارامتر برای اجرای کم‌هزینه روی CPUهای ضعیف. این مخزن checkpoint اصلی FP32 و NeMo را نگه می‌دارد؛ اندازهٔ کم با افت دقت نسبت به ریزه و کوچیک همراه است.
