I don't think it's worth to be a plugin if it's just a wrap to the deepl's SDK. users can call their SDK directly.

Thanks for the feedback.
The main value of the plugin isn’t just wrapping the DeepL SDK, but adapting it to the LiveKit agent runtime:
- DeepL’s SDK is synchronous, while agents require async, non-blocking execution
- The plugin integrates translation directly into the agent lifecycle (e.g. user turns, LLM flow) without users wiring it themselves
That said, I’m open to reducing scope or repositioning it (e.g. example / optional integration) if that fits better with the project direction.

Add a DeepL translation plugin to enable real-time, bidirectional multilingual support for LiveKit agents. The plugin integrates seamlessly into the agent pipeline, acting as a translation layer between STT/LLM and LLM/TTS components.
