Pindrop announces first-of-its-kind Deep Voice machine learning technology

Pindrop announced their proprietary Deep VoiceTM biometric engine, which utilises the latest deep neural network technology for speaker recognition, to passively identify legitimate and fraudulent callers, solely by voice. Pindrop’s Deep VoiceTM engine has expanded the company’s total addressable market from $2.5B to $7.8B with the introduction of a new authentication product, Pindrop® Passport.

Pindrop Passport is a multi-factor authentication solution that passively authenticates callers based on their voice, device and behaviour as they naturally engage with a call centre. Passport is powered by the first-of-its-kind Deep VoiceTM biometric engine that is able to recognise a caller by their voice even with short command-like utterances, regardless of if they are interacting in the IVR or with an agent.

“Our newly patented Deep Voice engine is creating new opportunities for Pindrop as we see voice eating all other interfaces,” said Vijay Balasubramaniyan, CEO and co-founder of Pindrop. “Establishing trust, security and identity is key to unlocking brand loyalty with consumers. With today’s product expansion we are delivering an end-to-end voice identity platform for enterprises looking to reimagine the customer experience as voice becomes the dominant interface of choice.”

Pindrop’s patented Deep VoiceTM biometrics was developed to address a number of shortcomings with the existing systems in the market such as poor enrolment rates and accuracy that are further exacerbated by short utterances and poor call quality. The Deep VoiceTM engine also brings enterprise grade voice security by detecting new voice attacks such as voice synthesis and distortion and will usher in a new era of enterprise virtual assistants, chatbots and frictionless customer experiences.

Passport is comprised of three core machine learning technologies: Deep VoiceTM biometrics engine, combined with Pindrop’s proprietary PhoneprintingTM technology and ToneprintingTM behavioural analytics technology. Passport runs passively in the background of every call and identifies a caller based on who they are based on their voice, what they have based on their device and what they do based on their behaviour. This replaces weaker forms of authentication that currently exist, including asking customers a set of knowledge based questions or laborious enrolment processes. Enterprises can now reduce call handle times by up to 55 seconds and call centre operations costs by up to $1.00 per call, as well as reduce fraud losses and customer churn.
