Definition
Meaning
A graphic representation of someone's unique voice characteristics, used for identification.
A distinctive pattern or set of vocal features that can identify an individual, similar to a fingerprint. In extended metaphorical use, it can refer to the recognizable style or signature quality of a person's voice or artistic expression.
Linguistics
Semantic Notes
The term combines 'voice' with the metaphor of 'print' (as in fingerprint), implying a unique, physical trace used for identification. It is primarily a technical noun but can be used metaphorically.
Dialectal Variation

Frequently Asked Questions
No. A voice recording is raw audio. A voiceprint is a processed, graphical or mathematical representation derived from a recording, used to identify unique vocal characteristics.
Yes, like many biometrics, voiceprints can potentially be spoofed by high-quality recordings, sophisticated voice synthesis, or skilled impersonators, though systems often include 'liveness' detection to counter this.
It is not common in everyday conversation. It is a specialist term used in technology, security, and forensic science contexts.
Rarely and informally (e.g., 'The system voiceprinted the caller'). It is overwhelmingly used as a noun. The standard verbs are 'to take', 'to record', or 'to create a voiceprint'.
