Clearspeed Voice Risk Assessment vs GoVivace Speaker Verification API

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. Pricing is available on request.

GoVivace Speaker Verification API enrolls a speaker’s voice and compares later speech with the resulting voiceprint. The manual recommends repeated samples totaling at least 60 seconds for enrollment. Developers can use REST requests or a WebSocket API, with a Python client example; the documented audio example uses 16-bit linear PCM at 8 kHz. API actions include enrolling, searching, deleting, disabling, and enabling speakers. Search can return closest enrolled matches with a chosen count and score threshold. Voiceprints are stored on the server, and deleting a speaker permanently removes that information. GoVivace generates API keys for authentication. Its developer materials describe encryption in transit, configurable encryption at rest, access controls, and audit logging. Authenti deployment options include managed cloud and private cloud or on-premise, with US, India sovereign, and EU-localized hosting choices. Audio and voiceprint retention can be configured per deployment. Pricing is on request; platforms are API and self-hosted.
