A database of emotional speech in a world that is not black or white but grey.

In Proc. Interspeech 2025, pages 4488–4492

In 2004, the Berlin Database of Emotional Speech (Berlin EmoDB) was made publicly available, and since then, it has been utilized in numerous studies on emotional speech, with over 3,000 citations. We now extend this database with original material that was previously absent from the distributed versions within the research community. This includes ambiguous samples that were not agreed upon by at least 80 % of the raters, the addition of glottograms for all samples, and a new rater label indicating the perceived naturalness of the samples.
