Systems and methods of generating device commands based upon spoken user commands are disclosed. An exemplary embodiment captures a series of images of a user of a media device, generates image information corresponding to the series of captured images, determines lip movement of the user from the generated image information, determines at least one spoken user command based upon the determined lip movement of the user, and determines a device command based upon the determined spoken user command. Then, the device command is communicated to, for example, a media presentation device, wherein an operation of the media presentation device is controlled in accordance with the determined spoken user command.

The STB of claim 1, further comprising: an external image capture device that is external to the STB, that is communicatively coupled to the processor system, and that is operable to generate image information corresponding to the series of captured images. 5. The STB of claim 1, wherein the at least one STB command is a first STB command based upon first identified lip movements of the user, and wherein the image information from the image capture device is used to determine a second STB user command based upon next identified lip movements of the user, wherein the first identified lip movements are next followed by the next identified lip movements, and wherein the second STB command is compared with the first STB command to verify the first STB command. 6. The STB of claim 1, further comprising: a power switch controllably coupled to the processor system; andat least one electrical outlet coupled to the power switch, wherein the electrical outlet is operable to provide power to a home device via a power cord of the home device that is coupled to the electrical outlet,wherein the processor system is configured to monitor movement of the user's lips to determine a home device command,wherein the home device command corresponds to a request to turn on the home device, andwherein the processor system causes the power switch to provide power to the electrical outlet in response to determining the home device command. 7. The STB of claim 1, wherein the STB is a video camera. 8. A method for generating device commands to control a set top box (STB) based upon spoken user commands, the method comprising: displaying an electronic program guide (EPG) on a display, wherein the EPG presents availability of programs that may be presented by the STB;capturing a series of images of a plurality of users in a media room viewing the displayed EPG; generating image information corresponding to the series of captured images;identifying an authorized user from among the plurality of users in the series of captured images;determining lip movement of the authorized user from the generated image information;continuously monitoring the lip movement of the authorized user;determining an engagement command from the continuously monitored lip movement of the authorized user;determining, only after determining the engagement command, at least one spoken user command associated with scrolling about the displayed EPG based upon the determined lip movement of the user;determining a STB device command, wherein the STB device command is configured to scroll about the EPG based upon the determined spoken user command; andscrolling about the EPG in response to determining the STB device command. 9. The method of claim 8, further comprising: communicating a media presentation device command to a media presentation device, wherein the media presentation device command corresponds to the STB device command, and wherein an operation of the media presentation device is controlled in accordance with the determined STB device command that is based upon the spoken user command. 10. The method of claim 8, wherein the STB is communicatively coupled to a television. 11. The method of claim 8, further comprising: determining a plurality of lip movements of the plurality of users from the generated image information; anddetermining at least one spoken user command based upon the plurality of determined lip movements of the plurality of users,wherein the STB device command associated with the determined engagement command and the determined at least one spoken user command is determined only when the determined lip movement is from the authorized user. 12. The method of claim 11, further comprising: identifying at least one of the users from the plurality of users as an unauthorized user; anddisregarding the spoken user command from the identified unauthorized user. 13. The method of claim 8, further comprising: determining a language that is spoken by the user, wherein the spoken user command based upon the determined lip movement of the user is further based upon the determined language. 14. The method of claim 8, further comprising: determining that the STB device command is associated with a home device; andcommunicating a device command to a power switch, wherein the home device receives power from an electrical outlet controlled by the power switch. 15.
