Abstract
A voiceprint module for in-vehicle voiceprint drift detection. The module may be configured for determining an archived voiceprint for an operator of a vehicle, generating a first real-time voiceprint according to in-vehicle utterances of the operator made while operating the vehicle, generating a first voiceprint deviation to quantify statistical distance between one or more probabilistic density functions associated with each of the first real-time and archived voiceprints, and updating one or more vocal characteristics of the archived voiceprint to generate an updated voiceprint in response to the first voiceprint deviation surpassing an update threshold.
