Abstract: A method and system is disclosed for remotely verifying attendance of a particular person at a predetermined confined area. Monitoring and verification is performed through a telephone network including a telephone on the premises of the location of confinement and a control center. Voice verification, using voice analysis of speech transmitted in a telephone call from the site to the center is performed during periodic testing. A voice template vocabulary is established for the individual and used for voice verification. Caller line identification of each incoming call is performed to verify that call originates from the appropriate location. The confined individual is required, either randomly or at scheduled intervals, by the system to call the control center and recite a statement including randomly selected words from the template vocabulary.
