Uni2005 ONNX
An ONNX export of the Uni2005 universal phoneme-recognition acoustic model
from 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, recorded here at
commit d9f1adaf47d3b3765b41f4177da62a051516d636. See NOTICE for
