Voice Control

Offline solution in 30 languages

In the context of the HMI 5.0 project, which describes multi-sensory and multi-modal communication between humans and machines, the audio channel plays an important role. While the output of signals and sounds is also supplemented by synthetic speech, voice control for input is also taking its place in professional applications. With it, devices can be operated comfortably without hands, without looking at the device.

Offline voice control does not require a connection to the Internet during operation. As a result, data remains private and secure. Data does not have to be stored on an external server, nor does broadband permanent access to the Internet have to be provided.
