elderLUCID: London UCL Older Adults' clear speech in interaction database

This collection contains the quantitative data resulting from the analysis of the elderLUCID audio corpus – a set of speech recordings collected for 83 adults aged 19 to 84 years inclusive. Recordings were made while participants carried out two types of collaborative tasks with a conversational partner who was a young adult of the same sex: (1) a ‘spot the difference’ picture task (‘diapix’) where the conversational partners had to collaborate to find 12 differences between their pictures and (2) a BKB sentence repetition task where the key participant had to read a set of sentences to their partner who had to repeat them back. The two tasks were carried out by each participant pair in four different conditions: (1) in good listening conditions when both could hear each other normally (NORM condition), or when perception was impaired for one or both of the participants by (2) simulating a severe-to-profound hearing loss in the conversational partner (HLS condition), (3) adding multispeaker babble noise to the audio channel for the conversational partner (BAB1 condition) or to the audio channel of both participants (BAB2 condition). The aim of the study was to examine the clarification strategies used by older adults and young adult controls to maintain effective communication in adverse communicative conditions. The SPSS spreadsheet contains, for each of the 83 participants, quantitative data resulting from (a) the acoustic analysis of the recordings, (b) measures of communication efficiency and (c) background auditory and cognitive measures.
