About product


Smart kitchen voice operated assistant to help automate your food routines, such as planning meals and grocery store visits.

The challenge was to find a proper solution for microphones and voice triggering to enable the device with far-field voice recognition feature. Finally we stopped at Analog Devices BF704 ADSP for 4-mic microphone array and STM32 for voice triggering. Meantime, the product contains a swivel gear, that complicates the voice processing algorithms. We cooperated with Sensory to develop a custom voice trigger phrase. Finally, we delivered a fully functional prototypes with demo scenarios.

The kitchen smart speaker should provide a new way how people use recipes. It should have a display to visualize a recipe content and provide step by step detailed cooking instructions.


RND64 has designed and found a way how to display the graphic information on the plastic surface by projecting the image onto the internal surface of the housing, which is coated by reflective paint. The working samples got a “Best Innovative product” award at ShowStoppers 2017 show.
