A system includes a memory and a semiconductor-based processor coupled to form logic circuits. The logic circuits generate a voice-enabled user interface (UI) framework for a computer application. The voice-enabled UI framework includes a base controller coupled to a model of the computer application and one or more views that form respective voice-enabled UIs of the computer application. Each view includes a respective speech listener configured to receive speech input. The base controller includes a speech engine, a natural language processor, and a command executor. The voice-enabled UI framework further includes one or more view-specific controller extensions extending the base controller to control the one or more respective views that form the respective voice-enabled UIs of the computer application.
