METHOD FOR CORRECTING SPEECH RECOGNITION RESULT AND COMPUTER PROGRAM FOR CORRECTING SPEECH RECOGNITION RESULT

摘要

PROBLEM TO BE SOLVED: To provide a correcting method for a speech recognition result which can optimize corrections of the recognition result although a reliability scale which can not stochastically be formulated is used. SOLUTION: This method includes a step 200 wherein a computer is made to operate to obtain a 1st reliability scale for each word included in a recognition result candidate of 1st order obtained through speech recognition processing outputting word strings of a plurality of recognition result candidates, a step 202 wherein the computer is made to operate to decide whether the 1st reliability scale satisfies specified relation with a predetermined threshold for each word, and steps 204 to 208 wherein the computer is made to operate to calculate a 2nd reliability scale for a corresponding word string included in recognition result candidates of 2nd order and below obtain through the speech recognition processing for each of successive word strings decided as word strings whose 1st reliability scales do not satisfy the specified relation with the threshold and substitute the word string having the highest reliability scale for the word string.
