1. A method, comprising: receiving a representation of an utterance; comparing the representation of the utterance with stored utterance data of a plurality of records, according to a match parameter, wherein the stored utterance data corresponds to a plurality of individuals associated with the plurality of records; identifying a set of candidate records from among the plurality of records based on a result of the comparing the representation of the utterance with the stored utterance data of the plurality of records according to the match parameter, wherein the result of the comparing the representation of the utterance represents a match of at least a threshold consistency between the representation of the utterance and the stored utterance data for a candidate individual associated with the set of candidate records; receiving ambiguity resolution information; comparing the ambiguity resolution information with stored ambiguity resolution criteria associated with the set of candidate records; identifying a candidate record from the set of candidate records based on a result of the comparing the ambiguity resolution information with stored ambiguity resolution criteria associated with the identified candidate record; verifying an identity of an individual associated with the utterance as the candidate individual associated with the identified candidate record based on the result of comparing the ambiguity resolution information with the stored ambiguity resolution criteria associated with the identified candidate record, and in response to failing to verify the identity of the individual associated with the utterance, creating a new record associated with the individual associated with the utterance.
