MEUSLI: open-source multilingual projector linking Whisper to LLMs for 28-language ASR

MEUSLI is a new open-science multilingual projector family that connects a Whisper speech encoder to open-source multilingual LLMs, enabling end-to-end ASR across 28 European languages. The system extends prior monolingual pipelines using continual learning techniques to support additional unseen languages and generalizes beyond ASR to speech translation and topic identification with minimal task-specific supervision. The work positions itself as a foundation for scalable, inclusive open-source SpeechLLM development.
