System and method for speaker authentication and identification

A non-transitory computer readable medium having stored thereon instructions for causing a processing circuitry to perform a process, the process comprising:

• generating a user account, the user account comprising:
• a user identifier based on one or more metadata elements associated with an audio input received from an end device;
• generating a first i-vector from an audio frame of the audio input, a trained T-matrix, and a Universal Background Model (UBM), wherein the first i-vector generation comprises an optimized computation;
• and
• associating the user account with the first i-vector, and wherein the optimized computation comprises:
• generating a feature matrix based on a feature vector;
• generating a Gaussian Mixture Model (GMM) mean matrix based on a plurality of mean vectors associated with a plurality of GMM components;
• and
• generating a delta matrix based on the feature matrix and the GMM mean matrix.

A system for enrolling a speaker in a speaker authentication and identification system (AIS), comprising:

• a processing circuitry;
• and
• a memory, the memory containing instructions that, when executed by the processing circuitry, configure the system to:
• generate a user account, the user account comprising:
• a user identifier based on one or more metadata elements associated with an audio input received from an end device;
• generate a first i-vector from an audio frame of the audio input, a trained T-matrix, and a Universal Background Model (UBM), wherein the first i-vector generation comprises an optimized computation;
• and
• associate the user account with the first i-vector, wherein the system is further configured to:
• generate a feature matrix based on a feature vector;
• generate a Gaussian Mixture Model (GMM) mean matrix based on a plurality of mean vectors associated with a plurality of GMM components;
• and
• generate a delta matrix based on the feature matrix and the GMM mean matrix.
