Abstract

Various embodiments of the technology described herein alleviate the need to specifically request enrollment information from a user to enroll the user in a voice biometric authentication program. For example, the system can receive a verbal request or a verbal command and non-voice biometric authentication information from a user. The user can be authenticated via a first authentication method using the non-voice biometric authentication information. After the user is authenticated using the first authentication method, the system enrolls the user into a voice biometric authentication program for at least one portion of the verbal request or the verbal command without requesting enrollment information.

First claim

What is claimed is:

1. A non-transitory, computer-readable medium containing instructions that, when executed by one or more processors, cause a machine to perform operations comprising:
receiving a verbal request or a verbal command and non-voice biometric authentication information from a user;
authenticating the user via a first authentication method using the non-voice biometric authentication information;
after authenticating the user via the first authentication method:
enrolling, without requesting enrollment information, the user into a voice biometric authentication program for at least one portion of the verbal request or the verbal command.

2. The non-transitory, computer-readable medium of claim 1 , wherein the operations further comprise: enrolling the user into the voice biometric authentication program for other verbal requests or other verbal commands that include the at least one portion of the verbal request or the verbal command and at least one portion of a second verbal request or a second verbal command for which the user has been enrolled into the voice biometric authentication program.

3. The non-transitory, computer-readable medium of claim 1 , wherein the operations further comprise: after enrolling the user into the voice biometric authentication program for the verbal request or the verbal command, authenticating the user via the voice biometric authentication program prior to fulfilling the verbal request or the verbal command made subsequently.

4. The non-transitory, computer-readable medium of claim 1 , wherein the voice biometric authentication program authenticates the user via a voice biometric authentication method, wherein the voice biometric authentication method includes:
receiving a subsequent voice interaction including the verbal request or the verbal command;
deriving characteristics of a voice from the subsequent voice interaction;
comparing the characteristics of the voice in the subsequent voice interaction with characteristics previously derived from one or more previously received voice interactions from the user including the verbal request or the verbal command; and
authenticating the user when a match of the characteristics of the voice in the subsequent voice interaction and the characteristics previously derived from the one or more previously received voice interactions meet or exceed a threshold.

5. The non-transitory, computer-readable medium of claim 1 , wherein the voice biometric authentication program uses text-dependent speech recognition to authenticate the user.

6. The non-transitory, computer-readable medium of claim 1 , wherein the operations further comprise: enrolling the user into the voice biometric authentication program for other requests or commands that include the at least one portion of the verbal request or the verbal command and at least one portion of a second verbal request or a second verbal command for which the user has been enrolled into the voice biometric authentication program.

7. The non-transitory, computer-readable medium of claim 1 , wherein the operations further comprise:
receiving a subsequent verbal request or a subsequent verbal command identifiable from a voice of the user;
determining an activity authentication level required to fulfill the subsequent verbal request or the subsequent verbal command;
analyzing characteristics of the subsequent verbal request or the subsequent verbal command, the characteristics including at least one of: pitch, intonation, speed, attenuation, accent, cadence, and volume;
authenticating the user via the voice biometric authentication program to an authentication level based on the characteristics of the voice speaking the subsequent verbal request or the subsequent verbal command; and
fulfilling the subsequent verbal request or the subsequent verbal command when the authentication level meets or exceeds the activity authentication level.

8. A system comprising:
at least one processor; and
a memory communicatively coupled to the at least one processor, the memory storing instructions which, when executed by the at least one processor, cause the at least one processor to perform operations comprising:
receiving a verbal request or a verbal command and non-voice biometric authentication information from a user;
authenticating the user via a first authentication method using the non-voice biometric authentication information;
after authenticating the user via the first authentication method:
enrolling, without requesting enrollment information, the user into a voice biometric authentication program for at least one portion of the verbal request or the verbal command.

9. The system of claim 8 , wherein the operations further comprise: enrolling the user into the voice biometric authentication program for other verbal requests or other verbal commands that include the at least one portion of the verbal request or the verbal command and at least one portion of a second verbal request or a second verbal command for which the user has been enrolled into the voice biometric authentication program.

10. The system of claim 8 , wherein the operations further comprise: after enrolling the user into the voice biometric authentication program for the verbal request or the verbal command, authenticating the user via the voice biometric authentication program prior to fulfilling the verbal request or the verbal command made subsequently.

11. The system of claim 8 , wherein the voice biometric authentication program authenticates the user via a voice biometric authentication method, wherein the voice biometric authentication method includes:
receiving a subsequent voice interaction including the verbal request or the verbal command;
deriving characteristics of a voice from the subsequent voice interaction;
comparing the characteristics of the voice in the subsequent voice interaction with characteristics previously derived from one or more previously received voice interactions from the user including the verbal request or the verbal command; and
authenticating the user when a match of the characteristics of the voice in the subsequent voice interaction and the characteristics previously derived from the one or more previously received voice interactions meet or exceed a threshold.

12. The system of claim 8 , wherein the voice biometric authentication program uses text-dependent speech recognition to authenticate the user.

13. The system of claim 8 , wherein the operations further comprise: enrolling the user into the voice biometric authentication program for other requests or commands that include the at least one portion of the verbal request or the verbal command and at least one portion of a second verbal request or a second verbal command for which the user has been enrolled into the voice biometric authentication program.

14. The system of claim 8 , wherein the operations further comprise:
receiving a subsequent verbal request or a subsequent verbal command identifiable from a voice of the user;
determining an activity authentication level required to fulfill the subsequent verbal request or the subsequent verbal command;
analyzing characteristics of the subsequent verbal request or the subsequent verbal command, the characteristics including at least one of: pitch, intonation, speed, attenuation, accent, cadence, and volume;
authenticating the user via the voice biometric authentication program to an authentication level based on the characteristics of the voice speaking the subsequent verbal request or the subsequent verbal command; and
fulfilling the subsequent verbal request or the subseq
