A system and method of verifying the identity of an authorized user in an authorized user group for enabling secure access to one or more services via a device includes receiving first voice information from a speaker through the device, calculating a confidence score based on a comparison of the first voice information with a stored voice model associated with the authorized user and specific to the authorized user, interpreting the first voice information as a specific service request, identifying a minimum confidence score for initiating the specific service request, determining whether or not the confidence score exceeds the minimum confidence score, and initiating the specific service request if the confidence score exceeds the minimum confidence score. |

1. A computer-implemented method of verifying the identity of a speaker as an authorized user in an authorized user group to a level necessary for enabling secure access to one or more services via a device, the method comprising:
receiving first voice information comprising a specific service request from a speaker through the device before verifying the identity of the speaker as an authorized user; calculating, by at least one processor, a confidence score that the speaker is an authorized user based on a comparison of the first voice information comprising the specific service request received before verifying the identity of the speaker as an authorized user with a stored voice model associated with the authorized user group and specific to the authorized user, wherein the at least one processor is included in at least one of the device and a server operatively coupled to the device through a communication network; interpreting, by the at least one processor, the first voice information as a specific service request; identifying, by the at least one processor, a type of service request comprising the specific service request; identifying, by the at least one processor, a minimum confidence score for initiating the type of service request comprising the specific service request; determining, by the at least one processor, whether or not the confidence score exceeds the minimum confidence score; and if the confidence score exceeds the minimum confidence score, initiating the specific service request; if the confidence score does not exceed the minimum confidence score, obtaining second voice information concerning the specific service request from the speaker through the device; calculating a confidence score based on a comparison of a combination of the first voice information comprising the specific service request and the second voice information concerning the specific service request with the stored voice model associated with the authorized user group and specific to the authorized user; and repeating the determining step. |
