Abstract
Abstract A speech recognition computer system and method indicates the level of confidence that a speech recognizer has in it recognition of one or more displayed words. The system and method allow for the rapid identification of speech recognition errors. A plurality of confidence levels of individual recognized words may be visually indicated. Additionally, the system and method allow the user of the system to select threshold levels to determine when the visual indication occurs.
