🐣🎙️ 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.

🚀 Load with NeMo
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.
