PURPOSE:To provide the specific task speech data base generating device which can greatly reduce the labor required to record speech data. CONSTITUTION:This device is equipped with a 1st appearance frequency calculating means 1 which calculates the 1st appearance frequency of a phoneme chain in an object sentence 7 of a specific task, a selecting means 2 which selects a subject in a general speech data base 8, a 2nd appearance frequency calculating means 3 which calculates the 2nd appearance frequency of the phoneme chain in the selected subset, a correlation value calculating means 4 which calculates the correlation value between the 2nd appearance frequency and 1st appearance frequency, a specifying means 5 which specifies the subset of a sentence having an appearance frequency closer to the 1st appearance frequency by utilizing the calculated correlation value, and a data base generating means 6 which selects speech information in the general speech data base 8 corresponding to the specified document and generates a speech data base 9 for specific task. |
