Abstract:
A method for making a combined weighted speech transducer for a large-vocabulary context-dependent speech recognizer based on signals representing: (i) the inverse, Câˆ’1, of a context-dependency transducer; (ii) a word pronunciation transducer, L; and (iii) a language model transducer, G; the method comprising the steps ofgenerating signals representing transducer C, the inverse of a determinized version of transducer Câˆ’1, generating signals representing transducer Pâ€², a determinized version of the composition Lâ€²BGâ€², which composition is a composition of disambiguated versions of each of said transducers L and G, generating signals representing a transducer P, a minimized version of transducer Pâ€², and generating signals representing said combined speech transducer as the composition C B P.
