The [FunASR](https://github.com/modelscope/FunASR#license) and [SenseVoice](https://github.com/FunAudioLLM/SenseVoice#license) repository source code is MIT; model weights follow each model card. [SenseVoiceSmall](https://huggingface.co/FunAudioLLM/SenseVoiceSmall) supports Chinese, Cantonese, English, Japanese, and Korean, and its weights use the linked FunASR Model Open Source License Agreement. [Fun-ASR-Nano-2512](https://huggingface.co/FunAudioLLM/Fun-ASR-Nano-2512) is Apache-2.0. Language coverage, punctuation, and performance depend on the selected model and runtime configuration.
