Abstract
A text data search using a voice is conventionally a full-text search using a word as an index word for a part recognized as a word in an input voice. Therefore, if any of the parts recognized as the words is falsely recognized, a search precision is lowered. In the present invention, referring to a language model generated by a language model generating part from text data to be subjected to a search which is divided by a learning data dividing part into a linguistic part and an acoustic model obtained by modeling voice features, a voice recognition part performs voice recognition for the input voice to output a phonemic representation. A matching unit converting part divides the phonemic representation into the same units as those of a text search dictionary, which is obtained by dividing the text data to be subjected to the search into the units smaller than those of the language model. A text search part uses the result of division to make a search on the text search dictionary.
