| # Model Card for FullSubNet (IB-Robot) |
|
|
| FullSubNet speech enhancement model with cumulative Laplace normalization for |
| streaming 4-channel microphone array processing, packaged for the |
| [IB-Robot](https://atomgit.com/openeuler/IB_Robot) framework with three |
| deployments sharing one stream contract. |
|
|
| ## Deployments |
|
|
| | deployment | backend | artifacts | notes | |
| |---|---|---|---| |
| | `ascend_310p` | Ascend ACL (Ascend310P1) | stateful FB/SB OM pair | board-side streaming (LSTM state via state_links) | |
| | `ascend_310b` | Ascend ACL (Ascend310B1) | stateful FB/SB OM pair (`*_310b_origin.om`) | 310B board-side streaming | |
| | `torch_cuda` | PyTorch CUDA | — (ckpt in `assets/`) | host-side streaming executor | |
| | `torch_cpu` | PyTorch CPU | — (ckpt in `assets/`) | CPU fallback (watch the 128 ms hop budget) | |
| |
| All deployments share `tensor_model/fullsubnet/enhance` |
| (`observation.audio_4ch [-1,4] -> voice.audio_enhanced_4ch [-1,4]`) with a |
| stateful stream execution contract (`state_bank_mode: runtime_exclusive`, |
| `max_open_streams: 1`). |
| |
| ## Weights provenance |
| |
| - `assets/cum_fullsubnet_best_model_218epochs.tar` = Audio-WestlakeU/FullSubNet |
| official v0.2 release checkpoint (sha256 |
| `d08d09107eb276b8dc3d2d9fff995f4354a51fa3347125f52f8b9aea7c339f81`) |
| - The 310P stateful OM pair was converted from the same checkpoint |
| - `assets/cum_fullsubnet_best_model_218epochs.manifest.json` pins the digest and |
| `norm_type: cumulative_laplace_norm` (do not mix with offline-norm checkpoints) |
| |
| Note: the `.tar` file is the upstream PyTorch serialization container |
| (legacy `torch.save` format), loaded directly by `torch.load` — no extraction |
| step. |
| |
| ## Repository Structure |
| |
| - `inference_manifest.json` — deployment routing (schema v3, stateful stream contract) |
| - `assets/adapter.json` — algorithm contract (STFT 512/256, T=2, look-ahead 2) |
| - `assets/cum_fullsubnet_best_model_218epochs.tar` — Torch checkpoint |
| - `artifacts/ascend/fullsubnet/*.om` — stateful FB/SB OM modules (310P) |
| - `artifacts/ascend_310b/fullsubnet/*.om` — stateful FB/SB OM modules (310B) |
|
|
| ## Usage |
|
|
| Host: `voice_asr_service.speech_direction` with backend `stateful_torch_cuda` / |
| `stateful_torch_cpu`; board: select `ascend_310p` via the unified inference |
| runtime. |
