The optimized solution for your projects

embidio small consists of a main board, as well as two microphone boards, each with two digital microphones, which allow a span of up to 20 cm. These can be flexibly connected to an existing display or a new one to be integrated, so that complex systems and service robots can be controlled by voice input. Voice processing is either performed locally in the hardware of the target product or in a cloud.

Embidio small

embidio small can be integrated into systems that already have their own user interface, such as display or keys, and a speech processing. Thus you can lower your production costs substantially and connect embidio small fast and simply to your interfaces.
