VOICE RECOGNITION CORRELATION RULE LEARNING SYSTEM, VOICE RECOGNITION CORRELATION RULE LEARNING PROGRAM, AND VOICE RECOGNITION CORRELATION RULE LEARNING METHOD

摘要

A voice recognition rule learning device (1) is connected to a voice recognition device (20) which uses for correlation, a conversion rule between a first type character string expressing a sound and a second type character string forming a recognition result. The voice recognition rule learning device (1) includes: a character string recording unit (3) which records the first type character string and the corresponding second type character string; an extraction unit (12) which extracts a second type learning character string candidate formed by a plurality of second type elements linked to one another from a word recorded in a word dictionary (23); and a rule learning unit (9) which extracts a character string matched with at least a part of the second type character string of the character string recording unit (3) from the second type learning character string candidate so as to form a second type learning character string, extracts a first type learning character string from the first type character string of the character string recording unit (3), and adds to the conversion rule, the correspondence between the first type learning character string and the second type learning character string. Thus, it is possible to automatically add to the conversion rule, a new rule causing the voice recognition device to change the conversion unit without increasing an unnecessary conversion rule.
