Overview

Easy-to-use hardware platform for Voice User Interface (VUI) solutions based on the RA8M1 MCU.

This VUI partner-enabled solution is based on the RA family of 32-bit MCUs. The hardware platform is used for all VUI partner-enabled solutions provided by Renesas within the Renesas Ready Partner Network. It demonstrates how easy it is to control your system with a simple voice command interface without extensive coding experience or in-house expertise.

With the powerful RA8M1 MCU, you will build an enhanced working solution to recognize and execute your own voice commands and can deploy the Natural Language Understanding (NLU) model in a complete end-to-end AI/ML Voice solution.
