Claim 13:
14. A system comprising:
a database comprising non-transitory memory configured to store a plurality of audio signals having one or more speaker-independent characteristics; and
a server comprising a processor configured to:
apply a plurality of task-specific machine learning models on an inbound audio signal having the one or more speaker-independent characteristics to extract a plurality of speaker-independent embeddings for the inbound audio signal, wherein each respective machine learning model of the plurality of task-specific machine learning models includes a classification layer disabled after training of the respective machine learning model;
extract a deep phoneprint (DP) vector for the inbound audio signal based upon the plurality of speaker-independent embeddings extracted for the inbound audio signal; and
apply one or more post-modeling operations on the DP vector to generate one or more post-modeling outputs for the inbound audio signal.
