The first all-in-one solution that allows developers to simply and securely build an offline voice assistant
Get started with the Voice Development Kit, a solution by developers for developers.
Choosing the Voice Development Kit
We provide a solution that will solve everyone of your problems
Our technologies are 100% reliable
It works anywhere, anytime. VDK’s technologies will run offline with 100% of their capacities in remote locations and areas with poor to no connectivity.
We strive to ensure security and privacy
VDK’s technologies run locally and on-device, with no end-user voice data transferred or analyzed in the cloud. Our privacy safeguards at the product, algorithm, and business-model level enable compliance with the strictest data regulations.
Our technical stack is scalable
All-in-one doesn’t only mean that the range is exhaustive. It also means that every technology is compatible and complementary with each other. You can pile up technologies one at a time, following your needs.
We design everything for simplicity
Who said enabling voice in a product or service was hard? It doesn’t have to be. We put our know-how in the VDK so that anyone can build complex voice features without hurdles.
We are compatible with most frameworks
Our algorithms are small enough to provide advanced capabilities while requiring the minimum footprint available. You don’t have to sacrifice features for space, requirements, or device’s compatibility.
