Abstract

A system and methods for voice controlled operation of a media player are provided. In one embodiment, a method includes detecting user positioning of a microphone power switch to an off position, detecting user positioning of the microphone power switch to an on position within a predetermined period of time and entering a voice recognition mode, by the media player, based on the user positioning of the microphone power switch to the on position within the predetermined period of time. The method may further include detecting one or more output signals of the microphone, detecting a voice command based on the one or more output signals of the microphone, and controlling operation of the media player based on the voice command, wherein the media player outputs a graphical display associated with the voice command.

Claims

1. A method for voice controlled operation of a media player, the method comprising the acts of:

detecting user positioning of a microphone power switch to an off position;

detecting user positioning of the microphone power switch to an on position within a predetermined period of time;

entering a voice recognition mode, by the media player, based on the user positioning of the microphone power switch to the on position within the predetermined period of time;

detecting one or more output signals of the microphone;

detecting a voice command based on the one or more output signals of the microphone; and

controlling operation of the media player based on the voice command, wherein the media player outputs a graphical display associated with the voice command.

2. The method of claim 1, wherein detecting user positioning of the microphone power switch is based on a comparison of microphone output signals to a threshold voltage.

3. The method of claim 1, wherein entering the voice recognition mode comprises providing the one or more output signals of the microphone to a speech processor.

4. The method of claim 1, wherein the voice command relates to a media player command for one of playing, stopping, forwarding, reversing, pausing, and track selection of media output by the media player.

5. The method of claim 1, wherein the voice command relates to one or more of microphone volume adjustment, selecting an audio effect of the media player, and navigation of a displayed menu.

6. The method of claim 1, wherein the graphical display relates to one or more of a drop down menu, control menu and symbol associated with the voice command.

7. The method of claim 1, further comprising controlling operation media player output of one or more of audio, video and microphone output signals.

8. The method of claim 1, wherein the predetermined period of time relates to three seconds.

9. The method of claim 1, wherein voice controlled operation relates to voice controlled operation for one or more of karaoke, audio and video presentations, and interactive entertainment systems in general.

10. The method of claim 1, wherein the one or more output signals of the microphone are wirelessly received.

11. A system comprising:

a microphone having a power switch; and

media player electrically coupled to the microphone, wherein the media player is configured to;

detect user positioning of a microphone power switch to an off position;

detect user positioning of the microphone power switch to an on position within a predetermined period of time;

enter a voice recognition mode, by the media player, based on the user positioning of the microphone power switch to the on position within the predetermined period of time;

detect one or more output signals of the microphone;

detecting a voice command based on the one or more output signals of the microphone; and

control operation of the media player based on the voice command, wherein the media player outputs a graphical display associated with the voice command.

12. The system of claim 11, wherein the media player is configured to detect user positioning of the microphone power switch based on a comparison of microphone output to a threshold voltage.

13. The system of claim 11, wherein the media player enters the voice recognition mode by providing the one or more output signals of the microphone to a speech processor.

14. The system of claim 11, wherein the voice command relates to media player commands for one or more of playing, stopping, forwarding, reversing, pausing, and selecting media output by the media player.

15. The system of claim 11, wherein the voice command relates to one or more of microphone volume adjustment, selecting audio effects provided by the media player, and navigation of a displayed menu.

16. The system of claim 11, wherein the graphical display relates to one or more of a drop down menu, control menu and symbol associated with the voice command.

17. The system of claim 11, wherein the media player is further configured to output one or more of audio, video and microphone output.

18. The system of claim 11, wherein the predetermined period of time relates to three seconds.

19. The system of claim 11, wherein voice controlled operation relates to voice controlled operation for one or more of karaoke, audio and video presentations, and interactive entertainment systems in general.

20. The system of claim 11, wherein the media player is further configured to received the one or more output signals of the microphone wirelessly.

21. The system of claim 11, wherein the media player is further configured to output at least one of audio and video data based on stored data, data detected from a data disc, and data received form a network source.
