Abstract
An efficient method and system, particularly well-suited for correcting natural language understanding (NLU) commands, corrects spoken commands misinterpreted by a speech recognition system. The method involves a series of steps, including: receiving the spoken command from a user; parsing the command to identify a paraphrased command; displaying the paraphrased command; and accepting corrections of the paraphrased command from the user. The paraphrased command is segmented according to command language categories, which include a command action category, an action object category, and an action and/or object modifying category. The paraphrased command is displayed in a user interface window segmented into these command language categories. The user interface window also contains alternative commands for each segment of the paraphrased command.
