METHOD AND PROGRAM FOR ESTIMATING SPEECH RECOGNITION RATE

摘要

PROBLEM TO BE SOLVED: To provide a speech recognition rate estimating method in which a speech interaction system sequentially estimates an assumed recognition rate at speaking input points of time.

SOLUTION: The speech interaction system which provides information service through speech interaction between a user and a computer system has the stages of; inputting sound scores and language scores obtained by analyzing an input speech; inputting the speech recognition result at the time of the execution of an interacting operation; calculating total scores by adding the sound scores and language scores together; previously finding a correlation curve between the total scores and speech recognition rate according to the total scores and speech recognition result; and estimating a speech recognition rate for the total scores obtained by adding newly inputted sound score and language scores by reference to the correlation curve.
