Abstract

In a product including a speech recognition device for controlling at least one processing unit while using a command lexicon containing commands which depends as regards its contents on an activated operating state of a processing unit and which speech recognition device includes a command lexicon memory in which commands of the command lexicon can be stored in the form of command information and identification information assigned to the latter, and which speech recognition device includes speech recognition means for detecting command information—contained in speech information representing a spoken command—and delivers command information to the at least one processing unit, generating means are provided which are arranged for generating—after an operating state of a processing unit has been activated—which may be effected with the aid of command information detected in a spoken command—a command lexicon assigned to only this one activated operating state and for storing this command lexicon in the command lexicon memory.

Claims

1. A product, comprising:

at least one processing unit operable to be activated from a first operating state to a second operating state in response to a control information;

a speech recognition device operable to provide said control information to said at least one processing unit in response to a first speech information for activating said at least one processing unit to said second operating state,

wherein said speech recognition device is further operable to generate a command lexicon exclusively corresponding to said second operating state after an activation of said at least one processing unit to said second operating state in response to said first speech information.

2. The product of claim 1, wherein said speech recognition device includes

a recognition means for recognizing said activation of said at least one processing unit to said second operating state .

3. The product of claim 1, wherein

said command lexicon includes a command information corresponding to said second operating state;

and

said speech recognition device includes a detection means for detecting said command information and said control information after said activation of said at least one processing unit to said second operating state in response to said first speech information.

4. The product of claim 3, further comprising:

a windows processing unit for providing said command information and said control information to said detection means in response to an interrogation information from said detection means.

5. The product of claim 3, wherein

said command lexicon further includes an identification information;

and

said speech recognition device further includes an assigning means for assigning said identification information to said command information.

6. The product of claim 5, wherein

said speech recognition device further includes a command lexicon memory for storing said command information and said identification information.

7. The product of claim 6, wherein

said speech recognition device further includes a speech recognition means for retrieving said command information from said command lexicon memory and providing said command information to said detection means in response to a second speech information for activating said at least one processing unit to said second operating state.

8. The product of claim 7, further comprising:

a windows processing unit operable to activate said at least one processing unit to said second operating state in response to said control information,

wherein said detection means provides said control information to said windows processing unit in response to said command information.

9. The product of claim 1, further comprising:

a monitor for displaying a first processing window and a second processing window,

wherein said at least one processing unit includes a first processing unit operable to be activated to said first operating state to drive said first processing window and to be activated to said second operating state to drive said second processing window.

10. The product of claim 1, further comprising:

a monitor for displaying a first processing window and a second processing window,

wherein said at least one processing unit includes

a first processing unit operable to be activated to said first operating state to drive said first processing window, and

a second processing unit operable to be activated to said second operating state to drive said second processing window.

11. A speech recognition device, comprising:

a means for receiving a first speech information for activating at least one processing unit from a first operating state to a second operating state;

a means for controlling a first activation of said at least one processing unit to said second operating state in response to said first speech information; and

a means for generating a command lexicon exclusively corresponding to said second operating state after said first activation of said at least one processing unit to said second operating state.

12. The speech recognition device of claim 11, further comprising:

a means for detecting a command information corresponding to said second operating state after said first activation of said at least one processing unit to said second operating state,

wherein said command lexicon includes said command information.

13. The speech recognition device of claim 12, further comprising:

a means for assigning an identification information to said command information,

wherein said command lexicon further includes said identification information.

14. The speech recognition device of claim 13, further comprising:

a means for storing said command information and said an identification information.

15. The speech recognition device of claim 14, further comprising:

a means for receiving a second speech information subsequent to receiving said first speech information, said second speech information for activating said at least one processing unit to said second operating state; and

a means for utilizing said command information and said identification information as stored to control a second activation of said at least one processing unit to said second operating state in response to said second speech information.

16. A method, comprising:

receiving a first speech information for activating at least one processing unit from a first operating state to a second operating state;

controlling a first activation of said at least one processing unit to said second operating state in response to said first speech information; and

generating a command lexicon exclusively corresponding to said second operating state after said first activation of said at least one processing unit to said second operating state.

17. The method of claim 16, further comprising:

detecting a command information corresponding to said second operating state after said first activation of said at least one processing unit to said second operating state,

wherein said command lexicon includes said command information.

18. The method of claim 17, further comprising:

assigning an identification information to said command information,

wherein said command lexicon further includes said identification information.

19. The method of claim 18, further comprising:

storing said command information and said an identification information.

20. The method of claim 19, further comprising:

receiving a second speech information subsequent to receiving said first speech information, said second speech information for activating said at least one processing unit to said second operating state; and

utilizing said command information and said identification information as stored to control a said at least one processing unit to said second operating state in response to said second speech information.
