## LUCID ## The LUCID (London UCL Clear speech in Interaction) corpus consists of recordings of pairs of SSBE speakers carrying out the DiapixUK task. This is a spot-the-difference task where speakers must communicate with each other in order to find all of the differences between the two images of the same scene. The pictures are designed to elicit certain vocabulary items. DiapixUK is a modified version of the original Diapix designed specifically with a UK audience in mind. Each pair used three pictures, so there are three recordings per speaker. There are a number of versions of each picture, therefore each speaker pair did not use the same three pictures. The corpus was aligned as part of the SPADE project using MFA (note therefore that there will be some American/British English mismatches in transcription). **Number of speakers:** 40, 20F \ **Hours of speech:** Approx 8 \ **Years recorded:** 2009 \ **Data Guardian:** corpus hosted at SpeechBox: https://speechbox.linguistics.northwestern.edu/#!/home -corpus created by Valerie Hazan \ **Speaker dimensions:** speaker id, gender, approx recording year, dialect \ Speakers have an age range of 18-29 with a mean age of 23. ### Corpus Reference ### Baker, R & Hazan, V.
