VoiceSense is a text and language independent biometric speaker verification system that verifies the speaker’s identity in real time using a simple spoken phrase.
How it works
Everyone has a unique voiceprint and the ubiquitousness of computer microphones and mobile phones makes the voiceprint authentication an ideal two-factor authentication system for web and telecom applications.
Key Features:
[-]Text Independent
The core technology that supports VoiceSense is a text independent voiceprint verification engine. Based on this unique feature, VoiceSense can be configured to work in different operation modes, such as:
- Free Speech - The user is free to say anything while the verification is taking place.
- One-Time Password - The system asks the user to repeat a random phrase - a one-time password. This mode prevents the replay attack.
[+]Language Independent
VoiceSense is also totally independent of the language and accent that the user speaks in.
[+]Adaptive Learning
VoiceSense system can adapt voiceprints over time to take into account the ageing effects on an individual's voice.
[+]Fast Enrollment
The enrollment of VoiceSense is simple and short. During the enrolment, the user is asked to speak freely (Free Speech mode), or to repeat a selection of keywords provided by the system (One-Time Password mode). This one-time enrollment process takes less than one minute, and a unique voiceprint is then created for the user.
[+]Easy to Use
The authentication process is equally simple and brief. When the authentication is needed, the user is asked to speak freely (Free Speech mode), or to repeat a one-time password provided by the system (One-Time Password mode). A real-time voiceprint is then created and compared with the voiceprint stored in the system's voiceprint repository.
