US Patent 7233904 Menu-driven voice control of characters in a game environment

In a gaming system, a user controls actions of characters in the game environment using speech commands. In a learning mode, available speech commands are displayed in a command menu on a display device. In a non-learning mode, the available speech commands are not displayed. A speaker-independent context-sensitive speech recognition module contains a vocabulary of available speech commands. Use of speech commands is combined with input from a controller device to control actions of a character or characters in the game environment.
