| FAQs for Voice Verification (also called Voice Biometry) |
| What is voice verification? |
Voice verification is the process of comparing a voice sample with a stored, digital voice model, or voiceprint, for the purposes of establishing or verifying identity. It is typically used for verifying identity over the telephone.
|
| What are the advantages of voice verification? |
- Convenience: Voice verification systems are automated and can therefore be available 24x7. Also, voice verification systems are quick and easy to use.
- Cost-savings and efficiency: By automating functions such as password resets, help-desk or call-center staff will be able to focus on more complex service requests.
- Security: Voice verification helps prevent ID fraud by adding a biometric security layer.
|
| What is a voiceprint? |
A voiceprint is a digital representation of some of the unique characteristics of a caller’s voice. A voiceprint includes measurement of physiological characteristics, such as the nasal passages and vocal chords, as well as the frequency, cadence and duration of the vocal pattern. A voiceprint is not a recording or sound file – it cannot be played back into a voice biometrics system by an imposter.
|
| What happens during enrolment? |
In order to create a voiceprint, the user must first enroll his or her voice. This typically involves repeating one or two phrases or digit strings. The voiceprint is then created by measuring certain parameters from these voice samples. Enrolment usually takes less than two minutes.
|
| What happens to the enrolment voice samples? |
There is no requirement to record or store the enrolment audio samples, so they are typically either not recorded at all, or permanently deleted once enrolment is complete.
|
| Can a voiceprint be stolen and used for fraudulent purposes? |
The caller’s voiceprint, if somehow stolen from the secure, encrypted database, cannot be used to access a voice verification system. Even though a voiceprint is derived from a speech sample during enrollment, this speech sample cannot be obtained by reverse-engineering the voiceprint. The voiceprint is a digital, mathematical model and cannot be played back to spoof the user’s voice. Furthermore, the original voice samples provided during enrolment can be permanently deleted. In short, a stolen voiceprint is essentially useless.
