voiceprint
Sound-based identity marker
A voiceprint is a visual representation of someone's voice, showing the unique patterns of frequency, amplitude, and duration that distinguish one person's speech from another's.
Like a fingerprint, a voiceprint can theoretically identify an individual—used in forensic analysis and security systems for voice authentication: The system requires a voiceprint to unlock.
