1.1.3.1 Voice Identification
Recently, specialised systems have become available to identify individuals using speaker verification
(speaker recognition). In such systems, the user talks into a microphone linked to a computer.
This equipment converts the spoken words into digital signals, which are evaluated by the identification
software.
The objective of speaker verification is to check the supposed identity of the person based upon
their voice. This is achieved by checking the speech characteristics of the speaker against an existing
reference pattern. If they correspond, then a reaction can be initiated (e.g. ‘open door’). |
