| # Onsei iOS ONNX Model Packs |
|
|
| ONNX model packs exported for the Onsei iOS client from the following upstream models: |
|
|
| - [`Aratako/Irodori-TTS-500M-v3`](https://huggingface.co/Aratako/Irodori-TTS-500M-v3), source revision `236c1e56591279fc24e3c1bf6609fc06e48dde28` |
| - [`Aratako/Irodori-TTS-600M-v3-VoiceDesign`](https://huggingface.co/Aratako/Irodori-TTS-600M-v3-VoiceDesign), source revision `e863a3a93e652e09afeff3e84823a206a0a60314` |
| - [`Aratako/Semantic-DACVAE-Japanese-32dim`](https://huggingface.co/Aratako/Semantic-DACVAE-Japanese-32dim) |
| - Tokenizer from [`llm-jp/llm-jp-3-150m`](https://huggingface.co/llm-jp/llm-jp-3-150m) |
|
|
| These files are converted runtime artifacts, not new model weights. They are not affiliated with or endorsed by the upstream authors. |
|
|
| ## Packs |
|
|
| - `500m-v3/`: standard Japanese TTS and reference-audio voice cloning. |
| - `600m-v3-vd/`: VoiceDesign model with caption conditioning. |
|
|
| Each pack contains the split `context_kv.onnx` + `dit_step.onnx` execution path used by the Onsei iOS app, DACVAE encode/decode, speaker and text encoders, duration prediction, configuration, and tokenizer data. `manifest.json` records file sizes and SHA-256 digests used by the app to verify downloads. |
|
|
| ## Licenses and attribution |
|
|
| The Irodori-TTS model weights, Semantic-DACVAE model weights, and conversion code are distributed under the MIT License. The llm-jp tokenizer is distributed under Apache License 2.0. See `LICENSES/` and `THIRD_PARTY_NOTICES.md`. Each component remains subject to its own license; no relicensing is implied. |
|
|
| ## Responsible use |
|
|
| The upstream model cards request that users: |
|
|
| 1. Do not clone or impersonate a person's voice without explicit consent. |
| 2. Do not create misleading deepfakes or synthetic speech intended to spread misinformation. |
| 3. Recognize that text-only output may coincidentally resemble a real voice. |
| 4. Take responsibility for compliance with applicable law. |
|
|
| The ONNX export used here does not add a SilentCipher watermark. Applications using these files should clearly disclose synthetic audio where appropriate and must enforce consent for voice cloning. |
