| # Third-party notices - Align | |
| The bundled Align models were trained from speech and machine-generated alignment references. | |
| The source datasets and reference systems are not redistributed in this package. | |
| ## Training audio | |
| - **FLEURS** - Google - **CC BY 4.0**. Multilingual speech used for the production model. | |
| Dataset: https://huggingface.co/datasets/google/fleurs | |
| ## Reference generation | |
| - **Qwen3-ForcedAligner-0.6B** - Alibaba Qwen team - **Apache-2.0**. Primary word-boundary | |
| reference for all nine languages. The aligner is not included here. | |
| - **OWSM-CTC v4 1B** - ESPnet/WavLab contributors - **CC BY 4.0**. Used on the validation | |
| split to estimate CTC timing offsets and as a gross alignment-outlier detector where stable. | |
| OWSM timestamps are not averaged into the final references. The model is not included here. | |
| - **ESPnet** - ESPnet contributors - **Apache-2.0**. CTC inference and alignment tooling used | |
| by the training pipeline. | |
| ## Runtime frameworks | |
| Align links only Apple system frameworks, including Core ML, Accelerate, AVFoundation, and | |
| Speech. No third-party runtime library is bundled. | |
| The compiled Align weights, calibration policy, and Swift implementation are distributed under | |
| [`LICENSE.md`](LICENSE.md). Dataset and reference-model licenses remain with their respective | |
