Abstract

A speech-directed user interface system includes at least one speaker for delivering an audio signal to a user and at least one microphone for capturing speech utterances of a user. An interface device interfaces with the speaker and microphone and provides a plurality of audio signals to the speaker to be heard by the user. A control circuit is operably coupled with the interface device and is configured for selecting at least one of the plurality of audio signals as a foreground audio signal for delivery to the user through the speaker. The control circuit is operable for recognizing speech utterances of a user and using the recognized speech utterances to control the selection of the foreground audio signal.

Claims

1. A speech-directed user interface system comprising:

at least one speaker for delivering an audio signal to a user and at least one microphone for capturing speech utterances of a user;

an interface device for interfacing with the speaker and microphone and providing a plurality of different audio signals to the speaker to be heard by the user;

a control circuit operably coupled with the interface device and configured for selecting at least one of the plurality of audio signals as a foreground audio signal for delivery to the user through the speaker, the control circuit operable for recognizing speech utterances of a user and using the recognized speech utterances to control the selection of the foreground audio signal.

2. The speech-directed user interface system of claim 1 wherein the interface device provides a plurality of audio signals that include at least one of a natural human speech signal and a synthesized speech signal.

3. The speech-directed user interface system of claim 1 further comprising a radio device operably coupled with the interface device to provide an audio signal.

4. The speech-directed user interface system of claim 1 further comprising a processing device operably coupled with the interface device to provide an audio signal.

5. The speech-directed user interface system of claim 4 wherein the processing device includes a text-to-speech component for generating a synthesized speech signal.

6. The speech-directed user interface system of claim 1 wherein the interface device includes a plurality of selectable outputs for outputting the captured speech utterances of the user and the control circuit is configured for selecting at least one of the plurality of outputs for directing captured user speech utterances, the control circuit operable for recognizing speech utterances of a user and using the recognized speech utterances to control the selection of an output for captured speech utterances.

7. The speech-directed user interface system of claim 6 wherein at least one of the outputs includes a radio device.

8. The speech-directed user interface system of claim 6 wherein at least one of the outputs includes a processing device.

9. The speech-directed user interface system of claim 1 wherein the control circuit is contained in the interface device.

10. The speech-directed user interface system of claim 3 wherein the radio device is contained in the interface device to provide an audio signal.

11. The speech-directed user interface system of claim 4 wherein the processing device is contained in the interface device to provide an audio signal.

12. The speech-directed user interface system of claim 1 wherein the control circuit selects a foreground audio signal by changing the volume of that audio signal with respect to at least another of the plurality of audio signals.

13. The speech-directed user interface system of claim 1 wherein the control circuit selects a foreground audio signal by changing the spatial separation of that audio signal with respect to at least another of the plurality of audio signals.

14. The speech-directed user interface system of claim 1 wherein the control circuit selects a foreground audio signal by selecting a particular text-to-speech application for that audio signal with respect to at least another of the plurality of audio signals.

15. The speech-directed user interface system of claim 1 wherein the control circuit selects a foreground audio signal by providing at least one of a prefix tone, a background tone or other audio tone associated with the foreground audio signal.

16. The speech-directed user interface system of claim 1 wherein the interface device includes a network link component for linking to a remote device through a network.

17. A method of interfacing with a user with speech comprising:

delivering an audio signal to the user with at least one speaker and capturing speech utterances of a user with at least one microphone;

using an interface device for interfacing with the speaker and microphone and providing a plurality of different audio signals to the speaker to be heard by the user;

selecting, through the interface device, at least one of the plurality of different audio signals as a foreground audio signal for delivery to the user through the speaker.

recognizing speech utterances of the user and using the recognized speech utterances to control the selection of the foreground audio signal.

18. The method of claim 17 further comprising providing a plurality of audio signals that include at least one of a natural human speech signal and a synthesized speech signal.

19. The method of claim 17 further comprising using a radio device, operably coupled with the interface device, to provide an audio signal.

20. The method of claim 17 further comprising using a processing device, operably coupled with the interface device, to provide an audio signal.

21. The method of claim 20 wherein the processing device includes a text-to-speech component for generating a synthesized speech signal.

22. The method of claim 17 wherein the interface device includes a plurality of selectable outputs for outputting the captured speech utterances of the user and further comprising selecting at least one of the plurality of outputs for directing captured user speech utterances.

23. The method of claim 22 wherein at least one of the outputs includes a radio device.

24. The method of claim 22 wherein at least one of the outputs includes a processing device.

25. The method of claim 17 further comprising selecting a foreground audio signal by changing the volume of that audio signal with respect to at least another of the plurality of audio signals.

26. The method of claim 17 further comprising selecting a foreground audio signal by changing the spatial separation of that audio signal with respect to at least another of the plurality of audio signals.

27. The method of claim 17 further comprising selecting a foreground audio signal by selecting a particular text-to-speech application for that audio signal with respect to at least another of the plurality of audio signals.

28. The method of claim 17 further comprising selecting a foreground audio signal by providing at least one of a prefix tone, a background tone or other audio tone associated with the foreground audio signal.

29. The method of claim 17 further comprising linking to a remote device through a network.
