Introduced: January 2000

Additional Content IPC

speaker verification or authentication refers to verifying that the user claimed identity is real, otherwise he is an imposter. Speaker recognition, or identification, aims at determining who the user is among a closed (finite number) set of users. He is otherwise unknown. imposter imposters someone actively trying to counterfeit someone else’s identity.

IPC and CPC are identically structured here. All 8 subcodes exist in both systems.

IPC defines codes here since 2013.
