A method and system for error prevention and recovery of voice activated
navigation through a menu having plural nodes provides situation
dependent utterance verification by relating confirmation to utterance
determination confidence levels. In one embodiment, a high confidence
level results in implicit confirmation, a medium confidence level results
in explicit confirmation and a low confidence level results in a concise
interrogative prompt of a single word that requests the user to repeat
the utterance. In situations where voice recognition is difficult, dual
modality with DTMF navigation is provided as an option for menu
selections.
