Verification is the process of comparing a person’s “sample” voiceprint to their “base” voiceprint obtained during the enrollment process. If the voiceprints match, based on a probability score, the person’s identity is verified.
Text-dependent voice biometrics systems require a person to speak the same pass phrase(s) during enrollment and verification. Text–independent systems do not. The person can be asked to repeat a series of random pass phrases to capture a “sample” voiceprint. Or, the “base” and “sample” voiceprints can be obtained in the background – even without the person’s knowledge (ideal for forensic applications).

My Neighbor Secures Mobile Commerce Transactions with Voice Biometrics
Planet Payment, a multi-currency payment and data processor, based in Long Beach, NY, has deployed a mobile shopping application which uses voice biometrics to secure transactions. The product is called “Shop BuyVoice™’ and it enables shoppers to purchase items securely, from registered “Voice Store” merchants, over the phone.
According to their Website, Planet Payment works with merchants to set up their mobile commerce (“Voice”) stores. Shoppers also need to enroll and provide a “base” voiceprint. Enrolled shoppers can see a product in an ad, browse a storefront after hours, or respond to an in-store display, then call Shop BuyVoice and buy the item simply by saying the product code and verifying their identity (i.e., by entering their phone number and providing a “sample” voiceprint). Click here for a demo.
Another step closer to making voice biometrics a commercial reality.

Voice Biometrics Basics - Enrollment
Enrollment is the process of creating a “base” voiceprint for a person. Typically, the person (after their identity is verified) will be prompted to repeat a pass phrase three times. For example, “my voice is my password.” The voice biometrics system captures the person’s data and converts it to a “base” voiceprint. The “base” voiceprint is stored in a database for future use (i.e., identity verification).
