VoiceVantage VoiceCheck
Blacksburg, Virginia, United States
What it is
VoiceVantage VoiceCheck verifies a claimed identity by comparing a live voice sample with an enrolled voiceprint. The maker describes applications in call centers, banking and financial services, e-commerce, enterprise access, and government communications. It says voiceprint comparison works regardless of the speaker’s language, gender, or accent, and that enrollment takes less than a minute; typical voiceprints use about 20–30 Kbytes of storage.
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. Security options include “Or,” “And,” and “Sequential” decision rules plus an adjustable threshold. Platforms listed include Android, API, iOS, Linux, macOS, web, and Windows, with hybrid deployment. Pricing is on request.
