IPC: G10L15/18
Filed: 2000-06-01
Abstract: PROBLEM TO BE SOLVED: To quickly detect a recognition error with respect to a voice recognition error detector and a storage medium. SOLUTION: Documents as the source of a voice input 4 of a voice recognition device 5 are collected to make a preliminary document database 1. A preliminary document processing part 2 generates a word appearance position dictionary 3 from the preliminary document database 1 before the start of recognition processing. A recognition result processing part 7 uses the word appearance position dictionary 3 to take the sentence most similar to the recognition result 6 in the preliminary document database 1 as a basis (correct sentence) of error detection. The selected correct sentence and individual words of the recognition result are compared with each other, and recognized words which don't exist in the correct sentence are regarded as recognition errors to detect a recognition error detection result 8.  Recognition error detection procedures are simplified by supposing that one sentence in the preliminary document database 1 is the correct sentence.
