SayPay Technologies, a US-based payments start-up, has partnered with VoiceVault to offer transformational online and mobile payment solutions.

As part of the partnership, SayPay has integrated its mPayment platform with VoiceVault’s ViGo product that allows voice authentication into new and existing apps.

The deal will allow SayPay to transform bill payments, online checkout, and website sign-in using voice biometrics.

VoiceVault provides algorithms that analyze characteristics of a user’s voice, including three-dimensional modeling of their vocal and nasal tract as well as the user’s co-articulation between digits.

The alliance will see VoiceVault algorithms leveraging SayPay’s one-time use token to find repeat or manipulated audio segments from prior sessions, eliminating the risk of replay and man-in-the-middle attacks.

SayPay CEO Steve Hoffman said: "With SayPay, customers simply speak a unique, one-time use ‘SayPay code’ which provides a secure and low-friction customer experience for each transaction."
