| # ⚖️🎙️ 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. |

|
| ## 🚀 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. |
