Summary

LumenVox Active Voice Biometrics provides text-dependent voice authentication for enterprises seeking identity assurance beyond passwords, PINs, and security questions. It runs as containerized microservices on Kubernetes on-premises, in private or public clouds, or across hybrid environments. Its deep-neural-network engine supports active, passive, and hybrid voice authentication. Enrollment and verification can use any passphrase and language supported by the corresponding ASR engine. Anti-fraud features include playback, liveness, and synthetic-speech detection, along with fraud watchlists. APIs can create, retrieve, disable, re-enable, and remove identities and check enrollment status. Biometrics, Speech, Management, and Reporting APIs are available through gRPC and REST. Supported channels include contact-center IVR, smartphone and web apps, desktop apps, virtual assistants, video calls, messaging platforms, and conversational AI. Enrollment requires at least three separate utterances of the selected passphrase. Audio must be supplied as headerless base64 byte streams in PCM-16, A-law, or μ-law at 8 kHz. Pricing is on request.
