CLEAR Labs

About CLEAR

The CLEAR Lab researches into methods for improving the intelligibility and quality of speech signals that have become corrupted with noise or distorted by transmission. CLEAR is a research project run jointly by Imperial College London (Department of Electrical and Electronic Engineering) and University College London (Department of Speech, Hearing and Phonetic Sciences).

CLEAR is funded by the UK Home Office to target the needs of law enforcement in the UK for information about the latest technologies for speech cleaning. Key objectives for the CLEAR project include:

• to establish repeatable, practical intelligibility testing methods
• to establish repeatable, practical speech audio quality testing methods
• to develop intrusive and non-intrusive measures of speech signal corruption and to research their relationship to intelligibility and quality
• to assess commercial and other non-commercial speech enhancement products with respect to their suitability for forensic and law enforcement applications
• to research, develop and evaluate advanced speech cleaning algorithms for law enforcement applications
