The new VDK will leave GAFAMs speechless

New AI-based development kit reinforces Vivoka’s mission to facilitate access to privacy-friendly voice technologies.

Metz – July 10, 2022 – Vivoka today announced VDK Silbo, a comprehensive AI-based voice technology solution that makes it very easy for companies to create their own multilingual, offline voice assistants while securing their own and their customers’ data.

In data-sensitive industries, cloud-independent voice interfaces are becoming increasingly preferred. Embedded voice recognition capabilities are increasingly popular with enterprises. GAFAMs, the market leaders in voice assistants, transmit their users’ data outside the company or home: although often confidential, this data is likely to be used by third parties. Without an internet connection, user data is preserved since it remains in the device or machine.


Simplicity pushed to the extreme


Based on Artificial Intelligence, VDK Silbo simplifies the complexity of voice technologies. Unlike most voice solution providers, it offers a solution that adapts to the customization needs of businesses, depending on the industry. With an intuitive, easy-to-use user interface and a streamlined workflow, VDK Silbo allows the user to simply create a multilingual voice interface that includes all the voice technologies needed to create an assistant (automatic voice transcription, text-to-speech, trigger word, grammar management, voice biometrics). This means rapid verification, integration and deployment of your own voice assistant.

Like the Silbo language, the whistled language of the Gomeros and one of the oldest and simplest languages in the world, VDK Silbo makes it extremely easy to create voice interfaces.

“In today’s world, speed of execution is the top priority for businesses. We are proud to announce today the first and simplest voice development kit that provides a level of abstraction that allows our customers to focus on what they want to do, not how they should do it. For Vivoka, simplicity is the ultimate sophistication. With VDK Silbo, creating a voice interface becomes a breeze,” said Vivoka CEO William Simonin.


From IoT to heavy industries


Already the market leader in voice-controlled smart glasses, Vivoka continues to expand into sectors such as logistics, healthcare, and aeronautics where data privacy is essential.
Vivoka offers the simplicity of a voice interface to any device, which allows it to position itself on the booming IoT market. The French scale-up has ambitions to continue its expansion, particularly in the nuclear, defense or weapons industries.

Thanks to their offline availability and RGPD compliance, Vivoka’s voice technologies are also suitable for application areas containing sensitive information, such as patient or government data.
