Clearspeed Voice Risk Assessment vs NamiTech VoiceDNA

Clearspeed Voice Risk Assessment analyzes vocal characteristics during short automated yes-or-no questionnaires and returns an indicator of potential risk. The system evaluates the voice signal while a person responds, rather than judging the answer itself. Assessments can be completed by phone or web, and the company describes operation across web, call center, and chat channels in more than 60 languages. Results are returned in seconds through the Clearspeed application or directly to customer systems. Enhanced synthetic-audio analysis runs in every questionnaire and, according to Clearspeed, detects synthetic voice and known deepfakes within 300 milliseconds. The Integration API manages questionnaire participants and sends results through webhooks. Clearspeed says no personally identifiable information, personal identifiers, historical data, or external data are required to generate an indicator. The cloud service uses AWS-backed environments, TLS 1.3 encryption, role-based access workflows, and stated GDPR, California, ISO 27001, SOC 2, and NIST 800-171 alignment.

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.
