| # Shenava — Rizeh Pizeh v1.0 (6.9M) · tract cache‑aware streaming (fp32) |
|
|
| **fp32 cache‑aware streaming** ONNX of [`Shenava-Rizeh-Pizeh-v1.0`](https://huggingface.co/Reza2kn/Shenava-Rizeh-Pizeh-v1.0) — **real‑time on a 2015 Cortex‑A7 (RTF ≈ 0.91)** via the tract Rust engine. Per‑step: `processed_signal` `[1,80,32]` + caches → `ctc_logits` `[1,3,1025]` + next caches (chunk 4, shift 3, left 64). |

| ## The Shenava‑1 family |
|
|
| A knowledge‑distillation cascade of on‑device Persian ASR models — one teacher distilled down to a 6.9M student. This model is one member; its siblings: |
|
|
| - [`Reza2kn/Shenava-Koochik-v1.0`](https://huggingface.co/Reza2kn/Shenava-Koochik-v1.0) — **Koochik v1.0** (114M) · teacher / flagship — on-device WER record |
| - [`Reza2kn/Shenava-Rizeh-v1.0`](https://huggingface.co/Reza2kn/Shenava-Rizeh-v1.0) — **Rizeh v1.0** (32M) · mid-tier student |
| - [`Reza2kn/Shenava-Rizeh-Pizeh-v1.0`](https://huggingface.co/Reza2kn/Shenava-Rizeh-Pizeh-v1.0) — **Rizeh Pizeh v1.0** (6.9M) · tiniest — real-time on a 2015 Cortex-A7 ◀ **this model (or its parent)** |
|
|
| ## Benchmark — fair WER/CER |
|
|
| ITN + Persian‑digit normalizer (the [double‑benchmark](https://huggingface.co/spaces/Reza2kn/persian-asr-double-benchmark) convention), decoded @ `att_context_size=[70,13]`. |
|
|
| | Member | golden‑6669 WER | CER | FLEURS‑fa WER | CER | |
| |---|---|---|---|---| |
| | Koochik v1.0 (114M) | **7.49%** | 2.30% | **10.64%** | 3.79% | |
| | Rizeh v1.0 (32M) | 12.11% | 3.94% | 14.45% | 5.10% | |
| | Rizeh Pizeh v1.0 (6.9M) | 24.55% | 8.89% | 26.95% | 10.22% | |
|
|
| Koochik v1.0 is **#2 on the public double‑benchmark, behind only cloud Gemini** — the best on‑device Persian ASR, beating a 1.5B Whisper‑Persian by >2× WER at 1/13 the size. |
|
|
| > fp32, not a quant — FastConformer sub‑fp16 in tract was never usable; the A7 real‑time result is fp32. |
