voiceprint
/ˈvɔɪsprɪnt
/noun
A visual record of speech, analysed with respect to frequency, duration, and amplitude.To many judges and lawyers involved in the criminal justice system, including leading experts on scientific evidence, voice identification has been equated with voiceprints and voiceprints are too unreliable....
- As with fingerprints, there are no two persons who have the same voiceprint.
- While proponents argue that voiceprints are analogous to fingerprints, detractors argue that, unlike fingerprints, voices can change due to illness, injury, or age, making voiceprints far less reliable.
Origin
1960s: from the noun voice, on the pattern of fingerprint.
