HIMSS Word of the Day #456: Voice ID (Voice Authentication)
Voice ID, or voice authentication, is a type of user authentication that relies on voice print biometrics, built on the idea that vocal characteristics are unique to each person. This post explains the HIMSS Dictionary definition, then reviews five sources: NIST’s 2025 digital identity guidance, which says biometric comparison based on voice shall not be used, a survey of 170 people on passwordless authentication methods, a survey of audio deepfake detection, a forensic study of cloned voices, and a study that used speech pause patterns to detect cloned audio.
