Bio-phonetic multi-phrase speaker identity verification
View Patent ↗Systems and methods for bio-phonetic multi-phrase speaker identity verification are disclosed. Generally, a speaker identity verification engine generates a dynamic phrase including at least one dynamically-generated word. The speaker identity verification engine prompts a user to speak the dynamic phrase and receives a dynamic phrase utterance. The speaker identity verification engine extracts at least one voice characteristic from the dynamic phrase utterance and compares the at least one voice characteristic with a voice profile the generate a score. The speaker identity verification engine then determines whether to accept a speaker identity claim based on the score.
1. A method comprising:
receiving private data, the private data (1) comprising private time-sensitive data associated with activities of a user, and (2) being stored in a computer system;
generating an alphanumeric word using the private data;
prompting the user to speak the alpha-numeric word;
extracting a voice feature from a received phrase in response to the prompting;
comparing, via a processor, the voice feature with a voice profile, to yield a comparison; and
determining whether to accept a speaker identity based on the comparison.
2. The method of claim 1 , further comprising receiving the received phrase.
3. The method of claim 1 , wherein the private data associated with the user further comprises biographical data associated with the user, wherein the biographical data comprises a place of birth of the user.
4. The method of claim 1 , wherein the private data associated with the user further comprises geographical data associated with the user, wherein the geographical data comprises a home address of the user.
5. The method of claim 1 , wherein the private data associated with the user further comprises email data.
6. The method of claim 1 , wherein prompting the user to speak the first dynamic phrase comprises:
transmitting a query to the user, wherein an answer to the query comprises the alpha-numeric phrase.
7. The method of claim 1 , wherein determining whether to accept the speaker identity comprises:
rejecting the speaker identity when a score based on the comparison of the voice feature with the voice profile indicates a low confidence level.
8. The method of claim 7 , further comprising tagging the alpha-numeric phrase as being attempted by an imposter.
9. The method of claim 1 , wherein determining whether to accept the speaker identity comprises:
accepting the speaker identity when a score based on the comparison indicates a high confidence level.
10. A computer-readable storage device having instructions stored which, when executed by a processor, cause the processor to perform operations comprising:
receiving private data, the private data (1) comprising private time-sensitive data associated with activities of a user, and (2) being stored in a computer system;
generating an alphanumeric word using the private data;
prompting the user to speak the alpha-numeric word;
extracting a voice feature from a received phrase in response to the prompting;
comparing the voice feature with a voice profile, to yield a comparison; and
determining whether to accept a speaker identity based on the comparison.
11. The computer-readable storage device of claim 10 , wherein the private data associated with the user further comprises biographical data associated with the user, wherein the biographical data comprises a place of birth of the user.
12. The computer-readable storage device of claim 10 , wherein the private data associated with the user further comprises geographical data associated with the user, wherein the geographical data comprises a home address of the user.
13. The computer-readable storage device of claim 10 , wherein the private data associated with the user comprises email data.
14. The computer-readable storage device of claim 10 , wherein prompting the user to speak the alpha-numeric phrase comprises:
transmitting a query to the user, wherein an answer to the query comprises the alpha-numeric phrase.
15. 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:
receiving private data, the private data (1) comprising private time-sensitive data associated with activities of a user, and (2) being stored in a computer system;
generating an alphanumeric word using the private data;
prompting the user to speak the alpha-numeric word;
extracting a voice feature from a received phrase in response to the prompting;
comparing the voice feature with a voice profile, to yield a comparison; and
determining whether to accept a speaker identity based on the comparison of the voice feature with the voice profile.
16. The system of claim 15 , wherein the private data associated with the user further comprises biographical data associated with the user, wherein the biographical data comprises a place of birth of the user.
17. The system of claim 15 , wherein the private data associated with the user further comprises geographical data associated with the user, wherein the geographical data comprises a home address of the user.
18. The system of claim 15 , wherein the private data associated with the user comprises calendar data.
19. The system of claim 15 , wherein prompting the user to speak the alpha-numeric phrase comprises transmitting a query to a user, wherein an answer to the query comprises the alpha-numeric phrase.
20. The method of claim 1 , wherein the data associated with the user is inaccessible to the user.
