Overview

Easy-to-use hardware platform for Voice User Interface (VUI) solutions based on the RA4E1 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.

You will build an enhanced working solution that recognizes your own voice commands to trigger the corresponding operation using the Renesas Partner Network Solutions utilizing the Voice Hardware Platform.
