The Belfast Naturalistic Emotional Database consists of 298 audiovisual clips from 125 speakers, 31 male, 94 female. Emotional clips are episodes which appear to provide within themselves at least most of the context necessary to understand a local peak in the display of emotion adn to show how it develops over time. For each speaker there is at least one clip showing him or her in a state judged relatively emotional, and also one clip in a state that the selector judged relatively neutral. Clips range from 10-60 secs in length. The clips are stored as MPEG files, with audio extracted into .wav files." (text extracted from E. Douglas-Cowie, R. Cowie and M. Schroeder, "The description of naturally occurring emotional speech", 15th ICPhS, Barcelona). Annotations in the corpus were generated using the FEELTRACE system.

The database has been provided as is to AMI partners by Prof. Roddy Cowie of Queen's University of Belfast, and may only be used for research purposes within the framework of the AMI project.
