METHOD AND APPARATUS FOR EVALUATING THE ACCURACY OF A SPEECH RECOGNITION SYSTEM

摘要

A method and system for evaluating the accuracy of a computer speech recognition system counts and indexes the total number of words dictated and the number of words corrected. The corrections are tallied after being made in a correction window and include words contained in an alternative list as well as words input by the user and within a stored word database. A processor calculates the approximate accuracy of the speech recognition system as the ratio of the number of correct words to the total number of words dictated. An accuracy ratio is calculated for each dictation session and an overall ratio is calculated for all sessions combined. The system also keeps individual and overall indexes of the number of times the corrected words were in alternate lists or not within the word database and uses these indexes to calculate additional accuracy values.
