RESTON, Virginia, April 8, 2015 /PRNewswire/ -- Global Tel*Link (GTL), the leading provider of correctional technology solutions, announces 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.
