Welcome to the Signal Analysis and Interpretation Laboratory (SAIL)
SAIL conducts fundamental and applied research in human-centered information processing.
Our emphasis is on speech, audio, language, biomedical and multi-modal signal processing,
machine learning and pattern recognition.
SAIL's research applications and systems development especially focus on domains with direct
societal relevance including in human health and well being (both basic and translational
research such as in the domains of autism, pediatric obesity and disordered speech production),
education (technologies for literacy and language learning) and defense (signal and pattern
classification, speech recognition and translation, virtual human-based systems and
audio-visual scene analysis).
SAIL supports a collaborative interdisciplinary environment and bridges research from several
departments and schools both within and outside USC. SAIL was established in November 2000
by Prof. Shrikanth Narayanan, who is also the
director of SAIL. Our research is supported by the NSF, NIH, DARPA, Army, ONR, and grants
from foundations and industry.
