Abstract

Disclosed is a secure telephone call management system for authenticating users of a telephone system in an institutional facility. Authentication of the users is accomplished by using a personal identification number, preferably in conjunction with speaker independent voice recognition and speaker dependent voice identification. When a user first enters the system, the user speaks his or her name which is used as a sample voice print. During each subsequent use of the system, the user is required to speak his or her name. Voice identification software is used to verify that the provided speech matches the sample voice print. The secure system includes accounting software to limit access based on funds in a user'"'"'s account or other related limitations. Management software implements widespread or local changes to the system and can modify or set any number of user account parameters.

5. The system of claim 1, wherein the plurality of inmate data records are indexed in the memory according to their respective first identifiers.

6. The system of claim 5, wherein the central site server is configured to select the selected inmate data record using the second identifier as a key to the indexed plurality of inmate data records.

7. A call management system for controlling access to a public telephone network, the system comprising:

a memory that stores a plurality of inmate data records, each of the plurality of inmate data records containing a corresponding first identifier and a corresponding single biometric sample, the single biometric sample being a spoken name of a corresponding inmate, and the plurality of inmate data records being indexed according to their respective first identifier; and

a central site server that provides communication services to multiple facilities, the central site server configured to, during each attempt to access the public telephone network by a user;

receive a second identifier from the user;

select, using the second identifier as a key to the indexed plurality of inmate data records, a selected inmate data record from among the indexed plurality of inmate data records whose first identifier matches the second identifier;

receive a biometric sample from the user;

compare the biometric sample only to the single biometric sample of the selected inmate data record; and

grant or deny the user access to the public telephone network to attempt to place a telephone call based on the comparison.

8. The system of claim 7, further comprising a biometric sensor configured to obtain the biometric sample from the user.
