apid consumer adoption of connected smart
speakers and voice assistants suggests that
many people prefer to control products with
speech rather than counterintuitive button
pushes. Consumers also seem to appreciate devices and
home appliances that are smart without being connected
to the cloud via the internet. The Renesas Electronics
voice user interface (VUI) solution, a third-generation
reference platform built on the scalable Arm®-based
RA2, RA4, and RA6 series of MCUs, is especially
targeted to applications in home automation, white
goods, and small appliances. The solution gives
access to a variety of developer tools and training
resources that will take product designs to the
next level, including design and training methods
of the integrated machine learning model and
full evaluation with online and offline methods.

Introduction
VUI is speech recognition technology that enables users
to interact with a computer, smartphone, or other daily-
use device with voice commands (Figure 1). The unique
feature of VUI is the use of voice as primary mode of
interaction, in contrast with traditional keyboard, mouse,
display, or touch screen.
The new, easy-to-use Renesas hardware platform for
VUI solutions is based on the high-performance Renesas
Advanced (RA) family of 32-bit microcontroller units (MCUs).
The RA family delivers key advantages compared to
competitive Arm Cortex®-M MCUs by providing stronger
embedded security, superior CoreMark® performance,
and ultra-low-power operation. PSA Certified provides
customers the confidence and assurance to quickly
deploy secure IoT endpoint and edge devices, and smart
factory equipment for Industry 4.0.
