Voice Biometrics Case Study – I DRIVE SAFELY

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.
