SAIL develops inclusive technologies and technologies for inclusion



SAIL focuses on human-centered signal & information processing that address key societal needs. Bridging science and engineering, SAILers pioneer behavioral signal processing and behavioral machine intelligence, affective computing, multimodal signal processing, computational media intelligence and computational speech science.

SAIL enables these through fundamental advances in audio, speech, language, image, video and bio signal processing, human and environment sensing and imaging, human-centered machine learning as well as applications developing speech, human language technologies, conversational and multimodal systems.

SAIL was established in 2000 by Professor Shrikanth (Shri) Narayanan and has made sustained contributions to numerous award winning papers, widely-used community resources, and broad impact through media mentions.

SAIL acknoweldges sustained support from federal agencies (NSF, NIH, DARPA, IARPA, DoD, ONR, DoJ etc), foundations as well as industry grants and contracts.
