Lexical access with lattice input
Hy Murveit, Mitchel Weintraub, Mike Cohen, J. Bernstein, Alexander I. Rudnicky · 2005
This paper describes an alternative approach to lexical access in the CMU ANGEL speech recognition system. Using this approach, the asynchronous phonetic hypotheses generated by an acoustic-phonetics module are converted to a directed graph. This graph is compared to a pronunciation dictionary. Performance results for this approach and the original CMU approach are similar. An error analysis indicates promising directions for further work.
