• Canonical repository: Reza2kn/Shenava-Koochik-v1.0
• PersianML mirror: PersianML/Shenava-Koochik-v1.0

🧠 Model

• Architecture: FastConformer Hybrid RNNT/CTC; the CTC head is used by the published deployment exports.
• Audio: mono, 16 kHz Persian speech.
• Encoder: d_model=512, 17 layers, 8x subsampling (about 80 ms per encoder step).
• Contexts: [70,13], [70,6], [70,1], and [70,0].
• Tokenizer: ve_tok_v4, SentencePiece BPE-1024 plus CTC blank.
• Output: Persian text. Numbers are emitted in spoken form; apply Persian inverse text normalization when digits are wanted.

The two .nemo filenames are compatibility aliases with identical content and SHA-256:
