Global Tel*Link Corporation Key Developments

Global Tel*Link Announces Release of Voice IQ

Global Tel*Link announced the release of Voice IQ the latest intelligence feature available for its inmate telephone platforms that solves issues of inmate identification on calls. Voice IQ, patented by GTL as a ‘Telecommunication call management and monitoring system with voiceprint verification,’ uses the latest in voice biometrics to track and verify the identity of inmates and prevent fraud. Using one of the most comprehensive natural language speaker verification tools in the speaker verification industry, Voice IQ builds a voiceprint profile for each inmate and enrolls that print in its repository for comparison in future calls. Unlike other technologies which analyze the calls after the call is completed, Voice IQ continuously compares portions of the call to the recorded voiceprint to verify the inmate's identity during the call. ITS users are able to detect fraud using the Voice IQ function, quickly and easily verifying an inmate's profile and identifying call records where Voice IQ has detected possible inmate speaker changes during the call.  A specific icon is displayed with a time stamp indicating when any speaker change activity was detected. Since the voiceprint repository builds as more inmates are enrolled, Voice IQ provides investigators with a powerful research tool that grows with their needs and as inmate voice prints are added, potentially extending to the over 1.1 million inmates utilizing GTL's inmate telephone services. Voice IQ slows the growth of inmate telephone fraud and helps investigators positively identify speaker change events related to criminal activity inside and outside of the facility. Voice IQ is one of many tools in the IQ family of intelligence products. Together, these products form the most holistic approach to intelligence gathering in the correctional industry, offering investigators a broad range of options for gathering pertinent, actionable intelligence.

Global Tel*Link Announces the Release of GTL Data IQ™, Version 5.8

Global Tel*Link announced the latest release of GTL Data IQ™, version 5.8, intelligence software that interfaces with all GTL products such as the GTL inmate telephone platform, financial transactions, email visitation, offender management systems, commissary orders and more. While other applications may be limited to analyzing their own data sources, GTL Data IQ can interface with any third-party data source such as state-owned data, county-owned data, publicly available data and data from facility vendors providing investigators a holistic view of investigative data. By transforming raw data into useful connections, GTL Data IQ combats fraud and other criminal activity. GTL Data IQ utilizes patented technology to empower investigators to consolidate and draw connections between offenders phone calls, visitations, trust and phone deposits, commissary accounts and more, thus giving them the power to detect, flag and act on suspicious or criminal behavior. The software is capable of performing a full link analysis of third-party data as well as any data from company's intelligence products. From financial transactions from any source to visitation and other forms of communication, GTL Data IQ draws connections where humans and other, less powerful software see none. Rather than relying on the difficult and time-intensive task of assembling and assessing large amounts of seemingly unrelated data by hand, GTL Data IQ uses advanced data mining technologies and a simple user interface to visually analyze a large and complex data set and help find offender-based fraud schemes and expose suspicious patterns or larger Security Threat Group (STG) networks, and generally provide a detailed view of the communications and interactions between offenders and others.
