Abstract: The present invention provides an Internet based system and method for monitoring the location of a subject at any time via telephone voice verification. The system and method enables an agency officer to enroll a subject's profile into a computerized system. The subject then responds to a series of verbally answered questions, the responses to which are utilized to establish a voice signature for the subject. Subsequently, the system and method automatically and periodically contacts the subject at pre-determined locations at pre-determined times to verify the subject's actual presence at the locations via voice verification software. The present invention also enables the agency officer to monitor and review compliance efforts implemented by the Internet based system while also providing notifications of non-compliance by the subject to the agency officer under criteria previously established by the officer.

Abstract: A system and method enrolls a speaker with an enrollment utterance and authenticates a user with a biometric analysis of an authentication utterance, without the need for a PIN (Personal Identification Number). During authentication, the system uses the same authentication utterance to identify who a speaker claims to be with speaker recognition, and verify whether is the speaker is actually the claimed person. Thus, it is not necessary for the speaker to identify biometric data using a PIN. The biometric analysis includes a neural tree network to determine unique aspects of the authentication utterances for comparison to the enrollment authentication. The biometric analysis leverages a statistical analysis using Hidden Markov Models to before authorizing the speaker.

Abstract: A telephone station interface is provided with apparatus for detecting when a called party has or is attempting to patch or bridge one telephone call with another telephone call. The detecting of such bridging or conferencing is accomplished through the detection of tones which are commonly associated with such activities, such as a ring signal, a busy signal, special information tones (SIT tones), dual tone multi-frequency (DTMF) tones or so-called Touch Tones, call progress tones, or other tones that occur when calls are placed. The present invention does not have the capability of sensing clicks, pops, or other audio signals associated with the conferencing of multiple communications circuits. The method and apparatus herein are for managing institutional telephone activity, and utilize a computer control unit to control a trunk management unit, which connects institutional telephones to outside telephone lines.

Abstract: A method and apparatus for detecting whether a remote party has added a secondary telephone destination to a telephone call, for example through the activation of three-way calling service, conference calling or two lining bridging, by identifying an echo characteristic to the telephone connection between the local and the remote telephone and monitoring the echo characteristic to determine whether there is a significant change. The addition of a secondary telephone destination can be verified by continuing to monitor the echo characteristic to determine whether it has returned to its original value.

Abstract: A method and apparatus for managing institutional telephone activity utilizes a computer control unit to control a trunk management unit, which connects institutional telephones to outside telephone lines. The computer control unit contains a database for storing the calling privileges and restrictions of institutional users and for recording calling transactions made by the users. The computer control unit implements a prospective call screening feature whereby outside recipients of undesired calls from the institution may enter a code that directs the computer control unit to prohibit similar calls in the future.

Abstract: A telecommunication system includes telecommunication resources, points, and a connection manager. The connection manager is configured to establish connections between the telecommunications resources and the points in response to a request from an application. The connection manager uses routing tables to select the most efficient route from the available routes between a telecommunications resource and a point. The routing tables establish the connection by sending a request to allocate a telecommunications resource to a session manager.

Abstract: An advanced three way call detection system which measures delay times associated with multiple echoes of a reference signal transmitted over a two way call. A reference signal is initially transmitted over a two way call when a two way connection is first established between a local telephone and a remote telephone. The echo characteristics of the two way connection are measured and recorded in an initial echo profile. The initial echo profile represents the number of and timing of each detected echo of the reference signal after transmission of the reference signal over the two way call when the two way connection is first established. The reference signal is then continuously transmitted at various timing intervals during the telephone conversation and the incoming line is sampled in order to detect echoed versions of the reference signal in order to create subsequent echo profiles.

Abstract: The voice print system of the present invention is a subword-based, text-dependent automatic speaker verification system that embodies the capability of user-selectable passwords with no constraints on the choice of vocabulary words or the language. An estimate of the enrollement channel and of the test channel is developed for inverse filtering of the enrollment or the test speech, respectively. Automatic blind speech segmentation allows speech to be segmented into subword units without any linguistic knowledge of the password. Subword modeling is performed using a multiple classifiers. The system also takes advantage of such concepts as multiple classifier fusion and data resampling to successfully boost the performance. Key word/key phrase spotting is used to optimally locate the password phrase. Numerous adaptation techniques increase the flexibility of the base system, and include: channel adaptation, fusion adaptation, model adaptation and threshold adaptation.

Abstract: The invention is a computerized system that allows inmates of a correctional institution to communicate with parties outside the facilities via telephonic or electronic messaging events. The system provides a means to bill for the events while controlling to whom the inmate can communicate with or from whom they may receive communications, including controlling the method, the length, limited content editing, the frequency of communicating, storage of and the manner of alerting a recipient of a message or receipt thereof.

Abstract: A system for controlling and monitoring the recording of telephone calls in institutions such as jails and correctional facilities, and for obtaining consent to such recording and monitoring. Calls are recorded automatically in response to the occurrence of specific triggering events, as pre-defined under software control by a system administrator. Triggering events may include, for example, use of a specific line, attempts to use particular features (such as three-way calling), attempts to dial particular telephone numbers, or use by a particular person. Consent to recording or monitoring is obtained from either the calling or called party, or both, in a language selected for such party. Evidence of which prompts were played to request consent, the language of such prompts, and whether consent was given is stored in a computer readable record. Recorded calls are digitized and stored in standard MS-DOS files on either a local computer system or a remote computer across a network.

Abstract: An inmate messaging system and method for notifying an inmate in a prison facility of messages received from a caller outside the prison facility. The caller dials into the inmate messaging system using, for example, a conventional “touch tone” telephone. The caller is prompted by the system for identifying information, which is verified against known information in a database. Identifying information can include a PIN for verifying the caller's account. During a set-up session, the system prompts the caller to record her name. The name recording is used to verify the account when the caller leaves a message for the inmate, and is also used to identify the account when the inmate retrieves the message from within the prison. The caller can specify a time with the message for returning the telephone call, or have the call placed immediately. The inmate accesses the inmate messaging system via a prison telephone.

Abstract: A telecommunication system includes a plurality of applications, a plurality of telecommunication resources, and a telecommunication services kernel. At least one telecommunication resource is capable of generating an event and each application is capable of responding to an event. The telecommunication services kernel couples a requested application triggered by the event with telecommunication resource required by the application. The telecommunication service kernel also de-couples the requested application and the required telecommunication resource in response to the requested application completing execution. The required telecommunication resource is now available to other applications. A method for allocating a telecommunication resource to an application in a telecommunications system is also disclosed.

Abstract: The model adaptation system of the present invention is a speaker verification system that embodies the capability to adapt models learned during the enrollment component to track aging of a user's voice. The system has the advantage of only requiring a single enrollment for the user. The model adaptation system and methods can be applied to several types of speaker recognition models including neural tree networks (NTN), Gaussian Mixture Models (GMMs), and dynamic time warping (DTW) or to multiple models (i.e., combinations of NTNs, GMMs and DTW). Moreover, the present invention can be applied to text-dependent or text-independent systems.
