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 microphone type and a current location of a speaker, a user profile from a plurality of user profiles, wherein the user profile is associated with the speaker; and

performing, via a processor, speech recognition on speech received from the speaker according to the user profile.

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

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

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

5. The method of claim 1, further comprising modifying an aspect of the speech recognition based on a speech adaption associated with the speaker.

6. The method of claim 5, wherein the speech adaptation is an accent change.

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

8. 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 microphone type and a current location of a speaker, a user profile from a plurality of user profiles, wherein the user profile is associated with the speaker; and

performing, via a processor, speech recognition on speech received from the speaker using the user profile.

9. The system of claim 8, wherein the user profile is specific to acoustics of the current location of the speaker.

10. The system of claim 8, wherein each user profile in the plurality of user profiles is associated with the speaker.

11. The system of claim 8, wherein the selecting of the user profile is further based on a recipient profile associated with a recipient of the speech.

12. The system of claim 8, wherein the computer-readable storage medium stores additional instructions 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 adaption associated with the speaker.

13. The system of claim 12, wherein the speech adaptation is an accent change.

14. The system of claim 8, wherein the computer-readable storage medium stores additional instructions 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 of the speaker.

15. 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 microphone type and a current location of a speaker, a user profile from a plurality of user profiles, wherein the user profile is associated with the speaker; and

performing, via a processor, speech recognition on speech received from the speaker using the user profile.

16. The computer-readable storage device of claim 15, wherein the user profile is specific to acoustics of the current location of the speaker.

17. The computer-readable storage device of claim 15, wherein each user profile in the plurality of user profiles is associated with the speaker.

18. The computer-readable storage device of claim 15, wherein the selecting of the user profile is further based on a recipient profile associated with a recipient of the speech.

19. The computer-readable storage device of claim 15, 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 modifying an aspect of the speech recognition based on a speech adaption associated with the speaker.

20. The computer-readable storage device of claim 19, wherein the speech adaptation is an accent change.
