`
`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 identifi(cid:173)
`cation 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.

`
`This application is a continuation-in-part of application
`Ser. No. 10/215,367, filed Aug. 8, 2002.
`
`FIELD OF THE INVENTION
`
`The present invention relates generally to the field of tele(cid:173)
`phone communication systems in penal institutions or similar
`facilities. In particular, the present invention relates to a com(cid:173)
`puter-based telecommunication system with the capacity to
`allow an institution to authorize, control, record, monitor, and
`report usage and access to a telephone network using speaker
`independent voice recognition and speaker dependent voice
`identification to ensure that access is restricted to authorized
`users only.
`
`BACKGROUND OF THE PRESENT INVENTION
`
`Generally, the need to monitor, control, record and provide
`detailed records of the usage of a telephone system in a
`controlled institutional environment is well recognized. It is
`common to utilize a controlled telephone system capable of
`monitoring outgoing telephone connections in many types of
`institutional environments, such as, but not limited to, penal
`institutions, military institutions, hospitals, schools, busi(cid:173)
`nesses, or specific types of government institutions. The rea(cid:173)
`sons for monitoring and controlling institutional telephone
`systems are evident. To prevent such institutions from incur(cid:173)
`ring unaccountable telephone costs, the institutions must
`either restrict access to outbound telephone lines or employ a
`telephone monitoring system to charge the responsible party
`for making the outbound communication. Otherwise, unac(cid:173)
`countable telephone costs would severally hinder the avail(cid:173)
`ability of the telephone systems in institutions.
`Therefore, it is imperative for many institutions to utilize a
`communication system that provides an accurate identifica(cid:173)
`tion means for administrators to determine the individual
`responsible for each outbound telephone call. A communica(cid:173)
`tion system must also provide a monitoring means for main- 45
`taining a useful record of the communication. Additionally,
`the system may include a means for restricting access or a
`means for providing options to particular users. Considering
`the nnmber of users in a large institution, different payment
`methods available, and the excessive call volume at many 50
`institutions, it is evident that an effective telephone manage(cid:173)
`ment system is essential.
`Providing telephone systems in specific types of highly
`restricted institutions, such as in penal institutions, results in
`the consideration of numerous additional complicating fac- 55
`tors. Generally, outbound communication means in penal
`institutions are heavily regulated by the government. There(cid:173)
`fore, communication systems implemented in penal institu(cid:173)
`tions or similar facilities must meet greater security require(cid:173)
`ments often mandated by regulatory bodies affiliated with the 60
`county, state, or federal institution. Thus, the communication
`system used in a regulated institution must employ unique
`functions.
`In its most general form, a penal institution's telephone
`system utilizes a call processor to approve and place a call,
`surveillance equipment or monitoring equipment, and a
`recording device for evidencing the conversation. Generally,
`
`2
`these simple systems are not equipped to restrict an inmate
`from calling any individual or to verify the identification of a
`user utilizing advanced authentication techniques. However,
`it is preferable for the call system devices now employed in
`such institutions to have the capability to thwart an inmate
`from calling certain specific individuals or types of individu(cid:173)
`als. Without the necessary constraints on an inmate's use of
`the telephone system, inmates have often harassed outside
`parties or individuals. For example, it is generally preferred
`10 that an inmate should not be able to place a telephone call to
`the prosecutor who prosecuted the inmate's case or another
`attorney responsible for the sentencing of the inmate. In
`another example, it may be preferred that an inmate be pre(cid:173)
`vented from contacting the victim of the inmate's crime or
`15 witnesses from the inmate's case. It has also been docu(cid:173)
`mented that inmates have used previous penal institution call
`systems to perpetrate additional criminal activities such as
`fraudulent schemes or specific criminal conspiracies. Specifi(cid:173)
`cally, inmates have been known to arrange credit card fraud
`20 attempts, the smuggling of contraband into the facility, and
`have even been known to arrange escape attempts over the
`penal institution's telephone system. Therefore, it is critical
`in an efficient penal institution to carefully monitor all out(cid:173)
`going telephone calls making a regulated penal institution
`25 telephone system a necessity.
`Another concern in implementing an efficient institution
`telephone system
