NamiTech VoiceDNA is an enterprise voice-biometrics platform for authentication, anti-fraud work, and deepfake detection. It verifies customers during natural conversation without passwords, security questions, or one-time passcodes. Enrollment can use as little as 10 seconds of voice, while later authentication can use as little as 4 seconds of live audio. Before processing, it screens samples for background noise, low volume, and overlapping speakers. Liveness detection is designed to identify voice clones, synthetic speech, text-to-speech, and physical replay attacks. VoiceDNA supports real-time audio streams and REST API integration, with API and self-hosted deployment options. NamiTech says it can run on CPU without a GPU in on-premises or cloud deployments, and supports 8 kHz telephony audio plus 16 kHz and higher. Listed uses include contact centers, banking, insurance, and fraud prevention. Pricing is on request.
