CONTROLLING USER INTERFACES WITH CONTEXTUAL VOICE COMMANDS

One or more voice-enabled user interfaces include a user interface, and a voice extension module associated with the user interface. The voice extension module is configured to voice-enable the user interface and includes a speech recognition engine, a preprocessor, and an input handler. The preprocessor registers with the speech recognition engine one or more voice commands for signaling for execution of one or more semantic operations that may be performed using a first user interface. The input handler receives a first voice command and communicates with the preprocessor to execute a semantic operation that is indicated by the first voice command. The first voice command is one of the voice commands registered with the speech recognition engine by the preprocessor.
