During yesterday’s Speech Technology webinar, William Morrow, Chairman and CEO of CSIdentity Corporation, presented a case study on the use voice biometrics in the distance learning space. In 2008, I DRIVE SAFELY, a provider of online defensive driving and traffic school courses, deployed the VoiceVerified® voice biometrics solution to enforce the academic integrity of students.
A 2009 Speech Technology article, by Judith Markowitz, described the enrollment and verification processes as follows:
Enrollment
• During the online registration process, the student provides their phone number
• An automated outbound call is made to the student and they are prompted to repeat six separate five-digit phrases (i.e., “base” voiceprint is captured and stored in the database)
Verification
• At key course intervals (e.g., completion of chapter, etc.), an automated outbound call is made to the student and they are prompted to verify their identity by repeating a five-digit phrase (i.e., “sample” voiceprint is captured)
• If the “sample” voiceprint matches the “base” voiceprint, the student’s identity is verified and they are permitted to advance to the next phase of the course
Since 2008, I DRIVE SAFELY has enrolled over 60,000 voice prints and completed over 300,000 verifications.

Hi,I've just came upon your site via google interested in voice biometrics authentication. I'm in the process of building a website that uses this technology.However, I'm only a researcher and a student for now. Do you know any sites that may offer any sort of open source codes or applications to experience with? Any help will be greatly appreciated.
ReplyDeleteYou may want to check out Voxeo's Website at http://www.voxeo.com/biometrics/ where I believe you can try several voice biometrics applications.
