A voice-enabled user interface includes a first user interface. A voice extension module is associated with the first user interface and is configured to voice-enable the first user interface. The voice extension module includes a speech recognition engine, an XML configuration repository, a preprocessor, and an input handler. The XML configuration repository includes one or more XML files specifying one or more voice commands for signaling for execution of one or more semantic operations that may be performed using the first user interface. The preprocessor is configured to register with the speech recognition engine the one or more voice commands. The input handler is configured to receive a first voice command and to communicate with the preprocessor to execute a semantic operation from the one or more semantic operations that may be performed using the first user interface. The first voice command is one of the one or more voice commands registered with the speech recognition engine by the preprocessor, and the first voice command signals for execution of the semantic operation.
