Abstract

Systems, methods, and computer-readable storage devices are for identifying a user profile for speech recognition. The user profile is selected from one of several user profiles which are all associated with a speaker, and can be selected based on the identity of the speaker, the location of the speaker, the device the speaker is using, or other relevant parameters. Such parameters can be hierarchical, having multiple layers, and can also be dependent or independent from one another. Using the parameters identified, the user profile is selected and used to recognize speech.

Claims

1. A method comprising:

selecting, based on a current location of a device, a profile associated with a user from a plurality of profiles; and

performing, via a processor and according to the profile, speech recognition on speech of the user.

2. The method of claim 1, further comprising selecting the profile based on a microphone.

3. The method of claim 1, wherein the profile is specific to acoustics of the current location.

4. The method of claim 1, wherein each profile in the plurality of profiles is associated with the user.

5. The method of claim 1, wherein the selecting of the profile is further based on a recipient profile associated with a recipient of the speech.

6. The method of claim 1, further comprising modifying an aspect of the speech recognition based on a speech adaptation associated with the user.

7. The method of claim 6, wherein the speech adaptation is an accent change.

8. The method of claim 1, further comprising presenting a query, wherein the query comprises a request regarding acoustics in the current location.

9. The method of claim 1, wherein the device is associated with the user.

10. A system comprising:

a processor; and

a computer-readable storage medium having instructions stored which, when executed by the processor, cause the processor to perform operations comprising;

selecting, based on a current location of a device, a profile associated with a user from a plurality of profiles; and

performing, according to the profile, speech recognition on speech of the user.

11. The system of claim 10, wherein the computer-readable storage medium stores additional instructions stored which, when executed by the processor, cause the processor to perform operations further comprising:

selecting the profile based on a microphone.

12. The system of claim 10, wherein the profile is specific to acoustics of the current location.

13. The system of claim 10, wherein each profile in the plurality of profiles is associated with the user.

14. The system of claim 10, wherein the selecting of the profile is further based on a recipient profile associated with a recipient of the speech.

15. The system of claim 10, wherein the computer-readable storage medium stores additional instructions stored which, when executed by the processor, cause the processor to perform operations further comprising:

modifying an aspect of the speech recognition based on a speech adaptation associated with the user.

16. The system of claim 15, wherein the speech adaptation is an accent change.

17. The system of claim 10, wherein the computer-readable storage medium stores additional instructions stored which, when executed by the processor, cause the processor to perform operations further comprising:

presenting a query, wherein the query comprises a request regarding acoustics in the current location.

18. The system of claim 10, wherein the device is associated with the user.

19. A computer-readable storage device having instructions stored which, when executed by a computing device, cause the computing device to perform operations comprising:

selecting, based on a current location of a device, a profile associated with a user from a plurality of profiles; and

performing, according to the profile, speech recognition on speech of the user.

20. The computer-readable storage device of claim 19, wherein the computer-readable storage device stores additional instructions stored which, when executed by the computing device, cause the computing device to perform operations further comprising:

selecting the profile based on a microphone.
