GoVivace Speaker Verification API vs Voiceme VoiceKey

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.

Voiceme VoiceKey is a B2B module for authenticating customers in digital services using voice recognition, facial biometrics, and device information. Its voice models compare vocal characteristics with stored samples, while facial recognition compares extracted features with stored ones. For a liveness check, VoiceKey can ask a user to repeat a randomly generated sentence and use speech-to-text to check the response. The sentence can expire within seconds, working as a short-lived voice code. Companies can choose authentication factors and configure settings such as sentence lifetime, accuracy, word count, and whether users supply the sentence. The platform supports web, mobile, physical devices, chats, chatbots, and voicebots, and is integrated with WhatsApp. APIs and Android and iOS SDKs support integration with existing systems. Voiceme offers SaaS or on-premises deployment and makes technical materials and integration flows available on request. The company says it stores mapping vectors rather than biometric audio or video files; customers define retention and deletion policies. Voiceme describes encryption and encrypted data fragmentation as data protections. Pricing is available on request, and the page invites prospective customers to request a demo.
