Voiceprint

A voiceprint, also known as a voice analysis, was an electronically recorded representation of a voice in graphical format. Each voiceprint was unique to the individual speaker. They could sometimes be imitated by voice duplicators, but strong software could detect the deception.
They were commonly used security methods to identify individuals when accessing critical or secured information, including on turbolifts. They had (for the most part) replaced retinal scans between the 21st and 24th centuries.
In 1968, a Beta 5 computer requested that a man identify himself. He responded for it to check his voice pattern, which would find him listed as Supervisor 194, code name Gary Seven. ()
