# ⚖️🎙️ Shenava Rizeh v1.0 · شنوا ریزه

The 32M-parameter middle tier of Shenava-1: a Persian FastConformer Hybrid RNNT/CTC model distilled with logit and feature knowledge distillation from the 114M [Koochik](https://huggingface.co/Reza2kn/Shenava-Koochik-v1.0) teacher. This repository contains the FP32 NeMo source checkpoint; published deployment formats live in separate repositories.

## 🧠 Model contract

- Audio: mono, 16 kHz Persian speech.
- Encoder: `d_model=256`, 16 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; numbers are spoken-form unless the display layer applies ITN.

## 📊 Published evaluation

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

| Set | WER | CER |

| visualears-golden-6669 | 12.11% | 3.94% |
| FLEURS-fa | 14.45% | 5.10% |

## 🚀 Load with NeMo

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

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

Choose Rizeh when Koochik’s accuracy/size trade-off is too heavy but the 6.9M Rizeh-Pizeh model is too small for the required accuracy.

## 🇮🇷 خلاصهٔ فارسی

«شنوا ریزه» مدل میانی ۳۲ میلیون‌پارامتری خانوادهٔ Shenava-1 است. این مخزن checkpoint اصلی FP32 و NeMo را نگه می‌دارد و برای ارزیابی، fine-tune یا تبدیل به قالب‌های اجرایی مناسب است.
