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.

Claims6

Dependent claims

An apparatus for restricting access to a telephone call management system, said apparatus comprising:

a speaker independent voice recognition module;
a speaker dependent voice identification module;
a RFID signal detect module;
a prompting module;
and
a database, wherein each entry in said database comprises an access RFID number, and an access speech sample;
wherein said prompting module prompts a user to provide a user access personal identification number (PIN) and a user speech sample;
wherein said speaker independent voice recognition module verifies each said user speech sample as indicative of said user's name;
wherein said user PIN is provided by said user as dual tone multi-frequency (DTMF) information;
wherein said RFID signal detect module authorizes said user to use said telephone call management system if said user is proximate to an RFID device with a valid RFID number;
wherein said speaker dependent voice identification module receives said user speech sample and compares it with said access speech sample corresponding to said access RFID number;
and
wherein said apparatus authorizes said user to use said telephone call management system if said user speech sample matches said access speech sample.
