GoVivace Speaker Verification API vs Recognition Technologies Speaker Recognition

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.

Recognition Technologies Speaker Recognition is a language- and text-independent voice biometrics system for identifying and verifying speakers. A person may enroll in one language and be identified or verified in another. The engine also supports classification, detection, tracking and segmentation. Identification can use open-set or closed-set approaches; closed-set identification can return the nearest enrolled voice even if the speaker is not in the database. The maker describes verification enrollment as about 30 seconds of speech, followed by a few seconds when the speaker returns. Interfaces include a C++ SDK/API, command line, web service, Android and iOS; the engine can also be used as a module of the maker’s IVR system. Deployment options include embedded, server-based, standalone, hosting at Recognition Technologies or hosting at the customer’s facilities. The product page lists Linux, Apple Macintosh OS X and Windows support. Its telephony version supports speaker verification and identification for telephone authentication and access-level control. Pricing is on request, and an evaluation account for the hosted version may be available to interested organizations.
