Speech Recognition

SUMMIT is a speech recognition system developed by the SLS group. This speech recognizer uses a landmark-based approach for modeling acoustic-phonetic events and utilizes finite-state transducer (FST) technology to efficiently represent all aspects of the speech hierarchy including the phonological rules, the lexicon, and the probabilistic language model.
