The Automatic Speaker Verification System is a module that uses the algorithms of Cedat of Automatic Speech Recognition System 85 to verify the identity of a speaker.
Users simply train the system by pronouncing 5 times a short passphrase. In a few minutes the system creates a model that describes the sentence pronounced in access with the vocal characteristics dell'oratore.A this point the system is able to verify the speaker's identity.
To be authenticated must pass two levels of security:
1. The first is the knowledge of the password. Like classic authentication systems, the Automatic Speaker Verification system checks that the user knows the secret password phrase. If the sentence pronounced upon authentication is different from the sentence of switched user, access will be denied.
2. The second and more innovative safety level is the speaker recognition. In fact, the system is able to determine whether the speaker who utters the passphrase is the same user who performed the training. In the event that someone else is familiar with the phrase of secret of a user, is the Automatic Speaker Verification system access is able to determine, based on the speaker's voice characteristics that it is an impostor, and then to deny him the 'access.
