Voice Biometrics Case Study - Bell Canada

In 2007, Persay and IBM Global Services Canada began the rollout of the first large-scale customer-facing voice biometrics system. It is only fitting that the client was Bell Canada. After all, in 1867, Alexander Graham Bell’s father began work on developing an early voiceprint.

Bell is Canada’s largest communications company. According to Persay’s Website, the principal project driver for Bell was to fight identity theft and make the privacy protection (i.e., verification) process more convenient for customers.

Enrollment process:
• Customer calls Bell’s contact center and is presented with the option to enroll using an IVR system
• If the customer opts in, the enrollment process is initiated. Or, if the customer opts out, they can ask for a re-prompt to enroll in 60 days
• Customer enrolls by repeating a pass phrase “At Bell, my voice is my password” three times (process takes approximately 2 minutes). The captured “base” voiceprint is stored in the database for future verification
• The enrollment is secured by the customer’s PIN and an account number and they are notified (via callback or SMS) when the enrollment process is completed

Verification process:
• In subsequent calls to Bell’s contact center, the customer is prompted to repeat their “At Bell, my voice is my password” pass phrase. The captured “sample” voiceprint is then compared to the customer’s “base” voiceprint
• If the voiceprints match, the customer is successfully verified and is automatically granted access to the IVR or a live agent (who is alerted that the customer’s identity has already been verified – saving time)
• Customer can add multiple voiceprints per account to enable access for additional authorized co-users (e.g., spouse)

To date, more than 2,000,000 Bell Canada customers have voluntary enrolled and verification rates exceed 4,000,000 a year.
