Edge Voice User Interface (VUI)

Overview

Description

As consumers seek more intuitive and hands-free ways to interact with their devices, an edge voice user interface (VUI) allows users to control systems like TVs, speakers, and smart appliances without the need for a remote or smartphone. This platform offers VUI designs based on the RA family of 32-bit MCUs. The versatile design serves as the foundation for VUI systems within the Renesas Ready Partner Network, supporting local endpoint inference for voice recognition without requiring network connectivity.

System Benefits​:

  • Powerful MCU allows for local endpoint inference, enabling voice recognition without network connectivity.
  • Low-power Arm® Cortex®-M33 MCU ensures energy-efficient operation, ideal for battery-powered devices.
  • Supports up to two digital microphones and two analog microphones.
  • Accommodates multiple microphone types for flexible integration in various audio environments.
  • External QSPI flash provides storage for voice samples and library data.
  • Communication interfaces include Pmod™ interface (Type-2A/3A/6A), USB Type-C, and Micro-B.
