Abstract

A processor-based system may utilize a remote control unit which not only allows mouse input commands to be provided to the processor-based system but also includes a microphone and a speech engine for decoding spoken commands and providing code for presenting the commands to the processor-based unit. The processor-based system may provide information to the remote control unit about the vocabulary currently being used by applications active on the processor-based system. This allows the speech engine in the remote control unit to focus on a more limited vocabulary, increasing the accuracy of the speech recognition function and decreasing the capabilities necessary in the remote control unit based speech engine.

Claims

1. A processor-based system comprising:

a first processor-based device having an airwave communication transceiver;

a remote control unit having an airwave communication transceiver to communicate with said first processor-based device, said remote control unit including a speech engine and a microphone coupled to said speech engine; and

wherein said first processor-based device includes software to provide information to the remote control unit about an application which is currently running and the vocabulary used by the application, and said speech engine being programmed to utilize a spoken command and provide code corresponding to said spoken command through said remote control unit transceiver to said first processor-based device.

2. The system of claim 1 wherein said system is a set top computer.

3. The system of claim 1 wherein said first processor-based device includes an interface to provide information about the currently active application running on said first processor-based device to said remote control unit.

4. The system of claim 3 wherein said first processor-based device includes software to provide a vocabulary set to the speech engine in the remote control unit.

5. The system of claim 1 wherein said communication links are infrared based.

6. The system of claim 1 including a driver that can receive tactile or spoken commands that are recognized by the remote control unit.

7. The system of claim 1 wherein said remote control unit is battery-powered.

8. The system of claim 1 wherein said remote control unit transmits code over said transceiver to said first processor-based device corresponding to spoken commands received at said remote control unit through said microphone.

9. A remote control unit comprising:

a processor implementimg a speech engine;

a microphone coupled to said processor;

an airwave transceiver to communicate with a remote device; and

wherein said speech engine is configured to operate on a limited vocabulary using information supplied from the remote device, indicative of the expected spoken command.

10. The remote control unit of claim 9 further including a set of mouse controls.

11. The remote control unit of claim 9 wherein said transceiver is an infrared transceiver.

12. The remote control unit of claim 9 wherein said processor includes software to send commands to the remote device when a spoken command is recognized by said speech engine.

13. A method comprising:

identifying an application currently active on a first processor-based device;

conveying information about the commands associated with said application to a second processor-based device;

receiving spoken commands at said second processor-based device using information from said first processor-based device to recognize said command; and

transmitting information from said second processor-based device to said first processor-based device based on the recognition of said spoken command.

14. The method of claim 13 further including communicating between said devices using an airwave communication technique.

15. The method of claim 14 further including sending signals between said first and second processor-based devices using infrared signals.

16. The method of claim 13 further including responding to both spoken and tactilely generated input commands.

17. The method of claim 13 wherein receiving spoken commands at said second processor-based device includes receiving said commands through a microphone in said second processor-based device.

18. The method of claim 13 including operating said second processor-based device using battery power.

19. The method of claim 13 further including transmitting mouse command input signals from said second processor-based device to said first processor-based device.

20. The method of claim 13 including receiving said spoken commands through a remote control unit.

21. An article comprising a medium for storing instructions that cause a processor-based system to:

receive a spoken command;

use a vocabulary received from a remote device to recognize the spoken command; and

transmit information to said remote device based on the recognition of said spoken command.

22. The article of claim 21 further storing instructions that cause a processor-based system to recognize mouse input commands and to transmit information about said input commands to a remote device.

23. The article of claim 21 further storing instructions that cause a processor-based system to receive a vocabulary related to an application receiving on said remote device.

24. An article comprising a medium for storing instructions that cause a processor-based system to:

identify an application currently active on said processor-based system;

convey information about the commands associated with said application to a remote processor-based device; and

receive information from said remote processor-based device based on the recognition of said spoken command.

25. The article of claim 24 further storing instructions that cause a processor-based system to communicate with said remote device using an airwave communication technique.

26. The article of claim 24 further storing instructions that cause a processor-based system to respond to both spoken and tactilely generated input commands.

27. The article of claim 24 further storing instructions that cause a processor-based system to receive mouse command input signals from the remote processor-based device.

28. The article of claim 24 further storing instructions that cause a processor-based system to transmit a portion of a total vocabulary to the remote device based on the currently active application on said processor-based system.
