VoiceVantage VoiceCheck verifies a person’s claimed identity by comparing a live voice sample with an enrolled voiceprint. The maker describes uses in call centers, banking and financial services, e-commerce, enterprise access, and government communications. Voiceprint comparison is described as language independent, regardless of a speaker’s language, gender, or accent. The Web REST API can add and remove users, enroll and verify them by voice, and configure users and the speech-processing engine. VoiceCheck Telephony integrates with IVR systems for caller authentication. The v3.2 SDK provides C++, .NET Framework 4.8, .NET Core 8, and Java interfaces with sample source code; VoiceCheck Mobile is an Android SDK with C++ and Java interfaces and sample applications. SDK decision rules include “Or,” “And,” and “Sequential,” alongside an adjustable security threshold. The maker says enrollment takes less than a minute, with typical voiceprints around 20–30 Kbytes. Listed platforms include Android, iOS, Linux, macOS, web, and Windows, and deployment is hybrid. Pricing is on request; SDK licensing details require contacting VoiceVantage.
