Abstract:
1. A system for acquiring, from an input text and an input speech, a set of a character string and a pronunciation thereof which should be recognized as a word, the system comprising: a candidate selecting unit comprising one or more processors executing stored program instructions for selecting, from the input text, at least one candidate character string which is a candidate to be recognized as a word; a pronunciation generating unit comprising one or more processors executing stored program instructions for generating at least one pronunciation candidate of each of the selected candidate character strings by combining pronunciations of all characters contained in the selected candidate character string, while one or more pronunciations are predetermined for each of the characters; a frequency generating unit comprising one or more processors executing stored program instructions for generating frequency data indicating appearance frequencies of the respective sets each constituting of a character string indicating a word and a pronunciation thereof, the frequency data generated by combining data in which the generated pronunciation candidates are respectively associated with the character strings, with language model data prepared by previously recording numerical values based on frequencies at which respective words appear in the text; a speech recognizing unit comprising one or more processors executing stored program instructions for performing, based on the generated frequency data, speech recognition on the input speech to generate recognition data in which character strings respectively indicating plural words contained in the input speech are associated with pronunciations; and an outputting unit comprising one or more processors executing stored program instructions for selecting and outputting a combination contained in the recognition data, out of combinations each consisting of one of the candidate character strings and one of the pronunciation candidates.
