Abstract:
PROBLEM TO BE SOLVED: To evaluate whether or not, there is a reading error in utterance.SOLUTION: A reading error creation part 161 of an utterance evaluation device 1 regards a word including a Chinese character out of words forming a sentence acquired from text data, as a processing object word, and then creates a way of reading of reading error. A sound production dictionary update part 162 associates the processing object word to which identification information is added, with the way of reading of reading error, and then registers, thereby updating a sound production dictionary. A language model update part 163 acquires association between words, from the text data, and based on association between words which is created by adding identification information to the processing object word included in the association between words, and a predetermined occurrence frequency applied to the created association between words, updates a language model. A recognition processing part 19 recognizes voice data based on the updated sound production dictionary and the language model. A user interface control part 14 outputs a reading error when the word to which identification information is added, is included in a result of voice recognition.SELECTED DRAWING: Figure 1
