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 voice interaction from a user where the voice interaction includes a request or a command having one or more portions. After the user is authenticated using non-voice biometric authentication information, the system enrolls the user into a voice biometric authentication program for at least one portion of the request or the command. The system also enrolls the user into the voice biometric authentication program for other requests or commands that include one of the at least one portion of the request or the command and portions of one or more second requests or commands for which the user has been enrolled into the voice biometric authentication program.

Claims

1. A computer-implemented method comprising:

receiving, via a network, a voice interaction from a user, wherein the voice interaction includes a request or a command identifiable from a voice of the user, wherein the request or the command includes one or more portions;

in response to receiving non-voice biometric authentication information, authenticating the user to fulfill the request or the command made during the voice interaction;

after the user is authenticated to or above an authentication threshold, enrolling the user into a voice biometric authentication program for at least one portion of the request or the command; and

enrolling the user into the voice biometric authentication program for other requests or commands that include the at least one portion of the request or the command and at least one portion of a second request or command for which the user has been enrolled into the voice biometric authentication program.

2. The computer-implemented method of claim 1, further comprising:

after enrollment into the voice biometric authentication program for the other requests or commands, authenticating the user via the voice biometric authentication program prior to fulfilling the other requests or commands made subsequently.

3. The computer-implemented method 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;

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; 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.

4. The computer-implemented method of claim 1, the method further comprising converting speech from the voice interaction into text, and wherein the voice biometric authentication program uses text-dependent speech recognition to authenticate the user.

5. The computer-implemented method of claim 1, the method further comprising:

receiving a series of voice interactions; and

creating a voice profile by analyzing the series of the voice interactions, wherein the voice interactions include at least two similar requests or commands.

6. The computer-implemented method of claim 1, wherein the user is enrolled when the user speaks the command or the request during at least two different voice navigations, wherein the method further comprises combining voice profiles of the at least one portion of the request or the command and the at least one portion of the second request or command to create a voice profile of the other request or command.

7. The computer-implemented method of claim 1, the method further comprising:

receiving, via the network, a subsequent request or command identifiable from the voice of the user;

determining an activity authentication level to fulfill the subsequent request or command;

analyzing characteristics of the subsequent request or 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 request or command; and

fulfilling the subsequent request or command when the authentication level meets or exceeds the activity authentication level.

8. A non-transitory, computer-readable medium containing instructions that, when executed by one or more processors, cause a machine to:

receive a voice interaction from a user, wherein the voice interaction includes a request or a command identifiable from a voice of the user, wherein the request or the command includes one or more portions;

in response to receiving non-voice biometric authentication information, authenticate the user to fulfill the request or the command made during the voice interaction;

after the user is authenticated to or above an authentication threshold, enroll the user into a voice biometric authentication program for at least one portion of the request or the command; and

enroll the user into the voice biometric authentication program for other requests or commands that include the at least one portion of the request or the command and at least one portion of a second request or command for which the user has been enrolled into the voice biometric authentication program.

9. The non-transitory, computer-readable medium of claim 8, wherein the instructions, when executed by the one or more processors, further cause the machine to:

after enrollment into the voice biometric authentication program for the other requests or commands, authenticate the user via the voice biometric authentication program prior to fulfilling the other requests or commands made subsequently.

10. The non-transitory, computer-readable medium of claim 8, wherein the voice biometric authentication program authenticates the user via a voice biometric authentication method, and wherein the instructions that, when executed by the one or more processors, cause the machine to authenticate the user via the voice biometric authentication method cause the machine to:

receive a subsequent voice interaction;

derive characteristics of a voice from the subsequent voice interaction;

compare 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; and

authenticate 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.

11. The non-transitory, computer-readable medium of claim 8, wherein the instructions, when executed by the one or more processors, further cause the machine to:

convert speech from the voice interaction into text, and wherein the voice biometric authentication program uses text-dependent speech recognition to authenticate the user.

12. The non-transitory, computer-readable medium of claim 8, wherein the instructions, when executed by the one or more processors, further cause the machine to:
