Prisons across the United States are reportedly building biometric databases that include voice recordings of incarcerated people, according to The Intercept. The report cites contracting documents for the state of New York's prison system, as well as statements from officials in Texas, Florida, Arkansas and Arizona confirming that prisons are actively using voice recognition technology that can extract and digitize voices to create unique and identifiable biometric signatures known as voice prints. According to the prisons, the systems are being used to improve security in the facilities and to combat fraud. Prisons can use the biometric identifier to track phone calls and find past communications that match the voice print of a particular person. The systems can also flag calls deemed to be suspicious to allow investigators to review the communications.
