Biometrics solutions have a modest equal error rate, which is defined in two ways:
- False rejection: When the system does not allow a user to pass through security, even though the user is authentic.
- False acceptance: When the system incorrectly allows a user to pass as another user because their voices sound very similar.
Thus, a voice biometrics solution’s equal error rate is calculated from the point at which false acceptance and false rejection rates are equal. Overall, this is below 5%, meaning that VotG has over 95% success ratio.
