| # Uni2005 ONNX |
|
|
| An ONNX export of the **Uni2005** universal phoneme-recognition acoustic model |
| from [Allosaurus](https://github.com/xinjli/allosaurus). It is published by |
| KitsuMate as a separately downloadable runtime model for |
| `ai.kitsumate.onnx.lipsync`; it is not bundled in the Unity package. |

| ## Model contract |
|
|
| - Input: `mfcc`, `float32`, shape `[batch, time, 120]` (dynamic batch/time). |
| - Output: `logits`, `float32`, shape `[batch, time, 230]`. |
| - Audio preprocessing: 8 kHz mono audio; 25 ms window; 10 ms hop; 40 MFCC |
| coefficients with speaker CMVN, three-frame context windows, and a factor-3 |
| subsample. The model does not perform resampling or MFCC extraction. |
| - Decode the output with CTC using `vocab.json`. |
|
|
| The repository currently publishes the full-precision export only. It has not |
| been qualified for every ONNX runtime or Unity AI Inference operator set. |
|
|
| ## Provenance and licence |
|
|
| The model is derived from the `uni2005` model in |
| [xinjli/allosaurus](https://github.com/xinjli/allosaurus), recorded here at |
| commit `d9f1adaf47d3b3765b41f4177da62a051516d636`. See [NOTICE](NOTICE) for |

|
| ## Use with KitsuMate ONNX |
|
|
| Pin a Hugging Face commit revision and verify the published SHA-256 before |
| placing the three runtime files in your application's model cache. Do not add |
| them to a UPM package archive. |
