LUCID Corpus - London UCL Clear speech in interaction
Rachel Baker and Valerie Hazan
The LUCID corpus is being made available to the Speech and Language research community for non-commercial research purposes.
- 40 native southern British English speakers (20 pairs)
- 20 male, 20 female
- 18-29 years old (mean age: 23 years)
- non-bilingual and normal hearing thresholds (20dB or below)
For each talker:
|Session1||DiapixUK (3 pix): casual speech||good listening conditions|
|Session2||DiapixUK (6 pix): clear speech (Cochlear Implant simulation)||each person hears vocoded speech for 3 pix|
|Session3||DiapixUK: (3 pix): clear speech (Noise or L2: 20 participants in each)||one person hears speech in multi-talker babble (Noise) or has a partner who is a low-proficiency English speaker (L2)|
|Session4||Picture naming & sentence reading: casual speech||'speak casually as is talking to a friend'|
|Session5||Picture naming & sentence reading: clear speech||'speak clearly as if talking to someone who is hearing-impaired'|
|Speech type||Speech style||Minutes per participant|
|spontaneous (DiapixUK)||casual, clear||110|
|read (sentences)||casual, clear||30|
|semi-spontaneous (picture naming)||casual, clear||30|
- Stereo wav files for two-way dialog and individual wav files for each speaker
- Word-aligned orthographic transcriptions (praat TextGrids format), apart from the speech for the L2 speakers
- Audio files, TextGrids and picture materials are all available (after password request to Valerie Hazan) from the OSCAAR Resource at Northwestern University: http://oscaar.ling.northwestern.edu/collection.php?c=19
We are grateful to our collaborator Prof. Ann Bradlow and her colleagues for enabling us to include the LUCID Corpus within this excellent resource.
