FOR IMMEDIATE RELEASE
Boston, Massachusetts. (JUNE 7, 2026) Frances M. Lynch, CEO of THC Technologies Corporation, a private corporation engaged in the global biometric solutions market, today said, “VoiceVantage™ products provide unmatched security features and benefits, and our extensive product portfolio and specialized consulting expertise support security authorities worldwide. Our voice verification biometrics solutions strengthen identity protection, and our unmatched speed and accuracy accelerate verifications ensuring timely, accurate and secure facilities access as well as protecting all levels and methods of communication security.
Our new product allow clients as well as VoiceVantage to offer a Cloud hosted, per license/per use service. The product is the VoiceCheck™ SaaS SDK. It is a .NET Wrapper for VC_Engine.DLL for SaaS Deployment.
In our VoiceCheck C++ SDK, the core VoiceCheck engine is packaged with the recorder and database components for a complete desktop or server solution. However, in the cloud environment no recorder or database component is necessary. Instead, only the VoiceCheck core technology is needed. The VoiceCheck™ SaaS SDK is a special version of our VoiceCheck verification engine. It consists only of the code that performs voiceprint extraction and comparison.
The core technology DLL was built using C++ and has an objected-oriented C++ native (i.e., “unmanaged”) interface. However, this is insufficient for use in a cloud environment using Microsoft .NET technology. To make this accommodation, an additional DLL was built to provide a .NET “managed” interface to the VoiceCheck core technology.
The VoiceCheck™ SaaS SDK contains the two DLLs mentioned above:
- VC_Engine_SaaS.dll: VoiceCheck core technology DLL with a “native” or “unmanaged” C++ interface.
- VC_Engine_SaaS_Net.dll: “managed” wrapper DLL for the “unmanaged” DLL with a .NET interface.
In addition to the above two DLLs, the VoiceCheck™ SaaS SDK also includes source code to a fully functional sample application written in C# that demonstrates the use of the .NET interface exposed by the VC_Engine_SaaS_Net DLL.
Technically speaking the VoiceCheck™ Engine SaaS SDK is a specially built version of the VoiceCheck™ Voice Verification Engine. It is designed to be deployed to a cloud environment to be used as Software As A Service. VC_Engine_SaaS_Net.dll is a companion DLL that can be deployed with VC_Engine_SaaS.dll, allowing access to the VC_Engine_SaaS.dll from a .NET development environment.
The VC_Engine_SaaS module supports the following features:
1) Create voiceprints from raw speech (e.g., PCM) or from a WAV file. All of the speech formats supported by our VoiceCheck™ SDK are also supported by the SaaS module.
2) Retrieve voiceprint for storage.
3) Retrieve statistics about the most recently created voiceprint (signal-to-noise ratio, speech length, frames removed, etc.)
4) Compare voiceprints
The SDK also includes a full Visual Studio 2022 solution and project with C# source code illustrating how to use the API exported from the VC_Engine_SaaS_NET DLL. An XML file is also included which provides documentation for the API when used with Visual Studio 2022.
