Speaker verification versus speaker identification


Speaker verification aims to verify the identity of the speaker through a comparison of some samples of his speech with the references of the speaker he claims to be.

Speaker identification aims to identify a speaker who belongs to a group of users through a sample of his speech.

One should distinguish the use of speech to identify/verify the speaker identity on the one hand from the recognition of the utterances he produces (password, PIN) to check his identity explicitly in a database on the other.
