Abstract

Methods and systems are provided for a speech system of a vehicle. In one embodiment, the method includes: generating an utterance signature from a speech utterance received from a user of the speech system without a specific need for a user identification interaction; developing a user signature for a user based on the utterance signature; and managing a dialog with the user based on the user signature.

Claims

1. A method for a speech system of a vehicle, comprising:

generating an utterance signature from a speech utterance received from a user of the speech system without a specific need for a user identification interaction;

developing a user signature for a user based on the utterance signature; and

managing a dialog with the user based on the user signature.

2. The method of claim 1 wherein the developing comprises developing the user signature based on the utterance signature and a stored user signature.

3. The method of claim 2 wherein the stored user signature is based on at least two previous utterance signatures.

4. The method of claim 3 wherein the stored user signature is further based on all or some of previous utterances in an interaction.

5. The method of claim 1 wherein the developing the user signature comprises determining that a user signature that is similar to the utterance signature does not exist, and storing the utterance signature as the user signature in a datastore.

6. The method of claim 1 wherein the developing the user signature comprises determining that a user signature that is similar to the utterance signature does exist, updating the user signature that is similar to the utterance signature with the utterance signature, and storing the updated user signature in a datastore.

7. The method of claim 6 wherein the determining that the user signature that is similar to the utterance signature does exist comprises determining that a user signature from a same transaction does not exist.

8. The method of claim 6 wherein the determining that the user signature that is similar to the utterance signature does exist comprises determining that a user signature from a different transaction does not exist.

9. The method of claim 1 further comprising substantially simultaneously managing a dialog with a second user based on a second user signature.

10. The method of claim 9 wherein the managing the dialog with the second user is further based on beam forming.

11. The method of claim 1 wherein the managing the dialog comprises adjusting at least one of a prompt and an interaction sequence with the user based on the user signature.

12. A speech system of a vehicle, comprising:

a first module that generates an utterance signature from a speech utterance received from a user of the speech system without a specific need for a user identification interaction;

a second module that develops a user signature for the user based on the utterance signature; and

a third module that manages a dialog with the user based on the user signature.

13. The speech system of claim 12 wherein the second module develops the user signature based on the utterance signature and a stored user signature.

14. The speech system of claim 13 wherein the stored user signature is based on at least two previous utterance signatures or based on a set of all or some previous utterances in an interaction.

15. The speech system of claim 12 wherein the second module develops the user signature by determining that a user signature that is similar to the utterance signature does not exist, and storing the utterance signature as the user signature in a datastore.

16. The speech system of claim 12 wherein the second module develops the user signature by determining that a user signature that is similar to the utterance signature does exist, updating the user signature that is similar to the utterance signature with the utterance signature, and storing the updated user signature in a datastore.

17. The speech system of claim 16 wherein the second module determines that a user signature that is similar to the utterance signature does exist by determining that a user signature from a same transaction does not exist.

18. The speech system of claim 16 wherein the second module determines that a user signature that is similar to the utterance signature does exist by determining that a user signature from a different transaction does not exist.

19. The speech system of claim 12 wherein the third module substantially simultaneously manages a dialog with a second user based on a second user signature.

20. The speech system of claim 19 wherein the third module manages the dialog with the second user based on beam forming.

21. The speech system of claim 12 wherein the third module manages the dialog by adjusting at least one of a prompt and an interaction sequence with the user based on the user signature.
