ECOLANG Corpus

The ECOLANG Multimodal Corpus of adult-child and adult-adult conversation provides audiovisual recordings and annotation of multimodal communicative behaviours by English-speaking adults and children engaged in semi-naturalistic conversation.<b>Corpus</b>The corpus provides audiovisual recordings and annotation of multimodal behaviours (speech transcription, gesture, object manipulation, and eye gaze) by British and American English-speaking adults engaged in semi-naturalistic conversation with their child (N = 38, children 3-4 years old) or a familiar adult (N = 31). Speakers were asked to talk about objects (familiar or unfamiliar) to their interlocutors both when the objects were physically present or absent. Thus, the corpus characterises the use of multimodal signals in social interaction and their modulations depending upon the age of the interlocutor (child or adult); whether the interlocutor is learning new concepts/words (unfamiliar or familiar objects) and whether they can see and manipulate (present or absent) the objects.<b>Application</b>The corpus<i> </i>provides ecologically-valid data about the distribution and cooccurrence of the multimodal signals for cognitive scientists and neuroscientists to address questions about real-world language learning and processing; and for computer scientists to develop more human-like artificial agents.<b>Data access requires permission</b>.To obtain permission to view or download the video data (either viewing in your browser or downloading to your computer), please download the user license at https://www.ucl.ac.uk/pals/sites/pals/files/eula_ecolang.pdf, fill in the form and return it to [e-mail].
