In the context of the FASiL project, we have studied natural language interactions in a unimodal (speech only) and multimodal (speech and graphics) interface to a personal information management database. We collected multilingual corpora to investigate these interactions in three languages: Portuguese, English and Swedish. The corpora are used to train language models, to update acoustic models, to study semantic concepts, multimodal interactions, and dialogue management strategies. The corpora are annotated in a uniform way, with timings, transcriptions, and semantics. In this paper, we report on the structure and design of the corpora which are now available via ELRA.
