  This paper presents Att-HACK, the first large database of acted speech with
social attitudes. Available databases of expressive speech are rare and very
often restricted to the primary emotions: anger, joy, sadness, fear. This
greatly limits the scope of the research on expressive speech. Besides, a
fundamental aspect of speech prosody is always ignored and missing from such
databases: its variety, i.e. the possibility to repeat an utterance while
varying its prosody. This paper represents a first attempt to widen the scope
of expressivity in speech, by providing a database of acted speech with social
attitudes: friendly, seductive, dominant, and distant. The proposed database
comprises 25 speakers interpreting 100 utterances in 4 social attitudes, with
3-5 repetitions each per attitude for a total of around 30 hours of speech. The
Att-HACK is freely available for academic research under a Creative Commons
