  • Method and system for performing speech recognition based on best-word scoring of repeated speech attempts
    Patent number: 6397180
    Abstract: A method and system for improving word classification performance of a speech recognition system having a predefined vocabulary of acceptable words and allowing multiple speech attempts from a user. At least one best word and corresponding word and non-word scores is determined for each speech attempt by the user. At least one common best word is then determined among all the speech attempts. If the highest ranking best word is common across all attempts, that word is used to accept the speech input. Otherwise, an objective measure representing a confidence level of the corresponding word and non-word scores is determined for each of the common best words for each speech attempt by the user. Each of the objective measures is then compared to a predetermined threshold. The speech attempts by the user is then classified based on the comparison of the objective measure to the predetermined threshold.
