In a computer speech user interface, a method and computer apparatus for automatically adjusting the content of feed back in a responsive prompt based upon predicted recogni tion accuracy by a speech recognizer. The method includes the Steps of receiving a user voice command from the Speech recognizer, calculating present Speech recognition accuracy based upon the received user voice command; predicting future recognition accuracy based upon the calculated present Speech recognition accuracy; and, generating feed back in a responsive prompt responsive to the predicted recognition accuracy. For predicting future poor recognition accuracy based upon poor present recognition accuracy, the calculating Step can include monitoring the received user Voice command; detecting a reduced accuracy condition in the monitored user voice command; and, determining poor present recognition accuracy if …
