All voice technologies inside one software development kit

The Voice Development Kit (VDK) is a multifunctional software development kit combined with an intuitive graphical user interface specialized for voice use cases. It allows any company and any developer to configure an offline voice solution composed of one or more voice-based technologies (transcription, synthesis, biometrics…) in record time.

For many years, Vivoka developed custom voice solutions for its customers. Each project was a real challenge since they required multiple technologies from many companies. Aggregating multiple solutions, partners and proprietary, is the aim of the Voice Development Kit.

The Voice Development Kit is the combination of a powerful SDK and an intuitive graphical user interface, the Studio. Resources from the engine can be used through smart widgets and tutorials to create any kind of embedded voice solution.
