A voice-activated user interface for an application is described. The voice activated user interface invokes a speech recognition component to recognize audio input from a user. If the audio input is a command, then a validation component is invoked to determine whether to validate the command prior to execution.

Selective confirmation for execution of a voice activated user interface

Upon selection of a displayed word, a list of alternatives for the selected word is displayed. Each alternative in the list has an associated symbol. A speech signal is then decoded to identify a list of possible words and the list of possible words is displayed with each possible word having an associated symbol.

Redictation of misrecognized words using a list of alternatives

Intelligent speech recognition is used to provide users with the ability to utter more user friendly commands. Satisfaction is increased when a user can vocalize a subset of a formal command name and still have the intended command identified and processed. Moreover, greater accuracy in identifying a command application from a user's utterance can be achieved by ignoring command choices associated with unlikely user utterances. An intelligent speech recognition system can identify differing acceptable verbal command phrase forms, e.g., but not limited to, complete commands, command subsequences and command subsets, for different commands supported by the system. Subset blocking words are identified for assistance in reducing the ambiguity in matching user verbal command phrases with valid commands supported by the intelligent speech recognition system.
