In total we are releasing approximately 12 hours of audiovisual data. For each improvised and scripted recording, we provide detailed audiovisual and text information, which consists of the audio and video of both interlocutors, the Motion Capture data of the face, head and hand of one of the interlocutors in each recording, the text trascriptions of the conversation and their word-level, phone-level and syllable-level alignment. Also, for each utterance of the recordings, we provide annotations into categorical and dimensional labels, from multiple annotators.

The previous limited IEMOCAP release, which contains only data from two actors only, is also available upon request.
