Systems and methods for providing network-based voice authentication

A system for performing speaker verification, comprising:

• a speech recognition and verification services engine operatively coupled to a first network;
• and
• a memory, operatively coupled to the speech recognition and verification services engine, to store user voice print profiles,
• where the speech recognition and verification services engine is to:
• receive a speaker verification call from a voice response engine over the first network;
• receive an authentication security level and a call indicator key associated with the speaker verification call from the voice response engine, the authentication security level being determined by the speech recognition engine before the speech recognition and verification services engine receives the authentication security level, where the authentication security level is one of a plurality of candidate authentication security levels;
• perform speaker verification on the received speaker verification call based on the stored user voice print profiles and the authentication security level associated with the speaker verification call;
• generate a verification score based upon results of the speaker verification;
• and
• match the verification score to the call using the call indicator key.

A method comprising:

• receiving, at a network device, a call that includes a transaction or access request from one of a plurality of telecommunications devices over a first network;
• passing the call to a speech recognition and verification services engine over the first network;
• transmitting a call indicator key and an authentication level to the speech recognition and verification services engine over a second network, the second network being different than the first network;
• receiving the call, over the first network, and the call indicator key, over the second network, by the speech recognition and verification services engine;
• performing speaker verification on the received call based on user voice print profiles and the authentication level;
• generating a verification score based upon results of the speaker verification;
• transmitting, by the speech recognition and verification services engine, the call indicator key and the verification score to the network device;
• matching, by the network device, the verification score to the call using the call indicator key;
• and
• one of permitting the request or denying the request based on the verification score.

A method for performing speaker verification, comprising:

• receiving a call from a voice response system over a first network;
• receiving an authentication security level and a call indicator key associated with the call from the voice response system, where the received authentication security level is one of a plurality of candidate authentication security levels, and is determined by the voice response system before the authentication security level is received from the voice response system;
• performing speaker verification on the received call based on stored user voice print profiles and the authentication security level;
• generating a verification score based upon results of the speaker verification;
• and
• matching the verification score to the call using the call indicator key.

A non-transitory computer-readable medium comprising instructions for controlling one or more processors to perform a method for performing speaker verification over a network, the method comprising:

• receiving a call, an authentication security level associated with the call, and a call indicator key associated with the call from a voice response system via the network, where the authentication security level is one of a plurality of candidate authentication security levels;
• performing speaker verification on the received call based on user voice print profiles and based on the received authentication security level;
• generating a verification score based upon results of the speaker verification;
• passing the call indicator key and the verification score to the voice response system for access determination after performing the speaker verification and generating the verification score;
• and
• matching the verification score to the call using the call indicator key.
