The preliminary research about fingerprint feature extraction and voiceprint
feature extraction is introduced in Section 3.
The VocalZoom optical HMC sensor converts this data into a voiceprint
associated only with the person who was actually speaking, and stores it inside the sensor.
Prominent phoneticians and engineers spoke up against using voiceprints
The device also includes voiceprint
recognition, a full keyboard and a smart card scanner, among other features.
Because no names are associated with the voiceprints
, the firm believes users will have no legal problems over data protection and privacy.
Others have suggested that, in the future, an e-signature could even be a retinal scan or voiceprint
electronically attached to a document.
The system then converts the sample into a voiceprint
and systematically compares the new voiceprint
with all or with a specified subset of the system's reference voiceprints
They can even hold identification photographs and more technologically advanced methods of identification, such as voiceprints
or fingerprint data.
As these three case studies show, developments in voice verification technology have made voiceprints
a viable identification tool in various applications.
Law enforcement agencies could use automated speaker identification technology in a number of ways, such as tracking individuals using wire or cellular phones, recording and identifying suspects in wire-tapping and other monitoring operations, and using voiceprints
for police sorting and booking operations.
The suspected malicious actor is then automatically referred for further investigatory steps; if necessary, the culprit is added to a watch list of fraudster voiceprints
and blocked from making future calls.
