Abstract

A speech-actuated control system for use with a consumer product, and in particular, in an automotive vehicle, recognizes a speech command and has a sequencer for after the recognition, effecting a change of state in the control. In particular, a plurality of different commands are recognized. The system has a mechanical actuator for, after the recognition, allowing a specifier command for specifying the most recently recognized speech command. The specifying effects a differential setting change in either of two opposite directions.

Claims

1. A speech-actuated control system for use in a consumer product, said control system comprising:

means for receiving a speech command from a user of said speech-actuated control system;

recognizer means for specifically recognizing a plurality of different speech commands from said receiving means, and for generating an output signal determined by the recognized speech command;

first operational means manually engagable by the user, the first operational means selectively coupling an output of said receiving means to an input of said recognizer means;

sequencing means having input for receiving the output signal of said recognizer means, the sequencing means effecting a change of state in said speech-actuated control system based on the output signal of the recognizer means, said change of state including the selection and engagement of one of a plurality of control functions of the consumer product, each of said control functions having at least one adjustable setting; and

second operational means manually controllable by said user for interfacing with the selected and engaged control function, the second operational means being enabled by said sequencing means thereby allowing the user to adjust said at least one adjustable setting of the selected and engaged control function.

2. A speech-actuated control system as claimed in claim 1, wherein said second operational means is bidirectionally active for effecting a differential adjustment in one of two opposite directions of said at least one adjustable setting of the selected control function.

3. A speech-actuated control system as claimed in claim 2, wherein said differential adjustment is discrete and cumulative.

4. A speech-actuated control system as claimed in claim 3, wherein said first operational means comprises an enabling actuator for enabling said recognizing means.

5. A speech-actuated control system as claimed in claim 2, wherein said first operational means comprises an enabling actuator for enabling said recognizing means.

6. A speech-actuated control system as claimed in claim 1, wherein said first operational means comprises an enabling actuator for enabling said recognizing means.

7. A speech-actuated control system as claimed in claim 6, wherein said speech-actuated control system further comprises continuously operative speech buffer means for receiving said speech command from said receiving means, wherein an output of said speech buffer means is coupled to the input of said recognizer means by said first operational means enabling recognition of speech stored in said speech buffer means immediately before actuation of said enabling actuator.

8. A speech-actuated control system as claimed in claim 6, wherein said enabling actuator is functionally integrated with said second operational means.

9. A speech-actuated control system as claimed in claim 6, wherein said enabling actuator is functionally integrated with said second operational means.

10. A speech-actuated control system as claimed in claim 6, wherein said speech-actuated control system further comprises timeout means, under control of any of said recognizer means and said enabling actuator, for starting a fixed-length time-out interval for said second operational means being enabled to adjust the at least one adjustable setting of said selected control function.

11. A speech-actuated control system as claimed in claim 1, wherein said consumer product comprises an audio signal generating system.

12. A speech-actuated control system as claimed in claim 1, wherein said second operational means has a default functionality.

13. A remote control arrangement comprising a speech-actuated control system for use in a consumer product, said speech-actuated control system comprising:

means for receiving a speech command from a user of said speech-actuated control system;

recognizer means for specifically recognizing a plurality of different speech commands from said receiving means, and for generating an output signal determined by the recognized speech command;

first operational means manually engagable by the user, the first operational means selectively coupling an output of said receiving means to an input of said recognizer means;

sequencing means having input for receiving the output signal of said recognizer means, the sequencing means effecting a change of state in said speech-actuated control system based on the output signal of the recognizer means, said change of state including the selection and engagement of one of a plurality of control functions of the consumer product, each of said control functions having at least one adjustable setting; and

second operational means manually controllable by said user for interfacing with the selected and engaged control function, the second operational means being enabled by said sequencing means thereby allowing the user to adjust said at least one adjustable setting of the selected and engaged control function.

14. A motor vehicle comprising a speech-actuated control system for use in a consumer product, said speech-actuated control system comprising:

means for receiving a speech command from a user of said speech-actuated control system;

recognizer means for specifically recognizing a plurality of different speech commands from said receiving means, and for generating an output signal determined by the recognized speech command;

first operational means manually engagable by the user, the first operational means selectively coupling an output of said receiving means to an input of said recognizer means;

sequencing means having input for receiving the output signal of said recognizer means, the sequencing means effecting a change of state in said speech-actuated control system based on the output signal of the recognizer means, said change of state including the selection and engagement of one of a plurality of control functions of the consumer product, each of said control functions having at least one adjustable setting; and

second operational means manually controllable by said user for interfacing with the selected and engaged control function, the second operational means being enabled by said sequencing means thereby allowing the user to adjust said at least one adjustable setting of the selected and engaged control function.

15. A motor vehicle as claimed in claim 14, wherein at least one of said first and second operational means is physically integrated in a steering actuator of said motor vehicle.

16. A motor vehicle as claimed in claim 14, wherein at least one of said first and second operational means enables recognition of a spoken radio data system command.

17. A motor vehicle as claimed in claim 14, wherein at least one of said first and second operational means enables recognition of a spoken radio data system command.
