….Dukes, who was released in October, says he was never told about what that procedure was meant to do. But contracting documents for New York’s new prison phone system, obtained by The Appeal in partnership with The Intercept, and follow-up interviews with prison authorities, indicate that Dukes was right to be suspicious: His audio sample was being “enrolled” into a new voice surveillance system.
In New York and other states across the country, authorities are acquiring technology to extract and digitize the voices of incarcerated people into unique biometric signatures, known as voice prints. Prison authorities have quietly enrolled hundreds of thousands of incarcerated people’s voice prints into large-scale biometric databases. Computer algorithms then draw on these databases to identify the voices taking part in a call and to search for other calls in which the voices of interest are detected. Some programs, like New York’s, even analyze the voices of call recipients outside prisons to track which outsiders speak to multiple prisoners regularly.
Corrections officials representing the states of Texas, Florida, and Arkansas, along with Arizona’s Yavapai and Pinal counties; Alachua County, Florida; and Travis County, Texas, also confirmed that they are actively using voice recognition technology today. And a review of contracting documents identified other jurisdictions that have acquired similar voice-print capture capabilities: Connecticut and Georgia state corrections officials have signed contracts for the technology (Connecticut did not respond to repeated interview requests; Georgia declined to answer questions on the matter)…..
