LumenVox Active Voice Biometrics
What it is
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, with deployment options spanning on-premises, private or public clouds, and hybrid environments. A deep-neural-network engine supports active, passive, and hybrid authentication. Enrollment and verification can use any passphrase and language supported by the corresponding ASR engine. Anti-fraud measures include playback, liveness, and synthetic-speech detection, plus fraud watchlists. APIs can manage 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 applications, virtual assistants, video calls, messaging platforms, and conversational AI. Enrollment requires at least three separate utterances of the chosen passphrase. Audio must be provided as headerless base64 byte streams in PCM-16, A-law, or μ-law at 8 kHz. Pricing is on request. The platform documents security guidance covering PCI DSS, HIPAA, and GDPR; its SaaS offering is described as SOC 2 compliant.
