Renesas Electronics and Cyberon Partner to Provide Embedded Voice User Interface Solutions for AR MCUs Supporting Over 40 Global Languages

TOKYO, Japan, and Taipei, TAIWAN ― Renesas Electronics Corporation (TSE:6723), a leading provider of advanced semiconductor solutions, and Cyberon Corporation, a leading provider of embedded voice solutions, today announced that they have partnered to provide solutions voice user interface (VUI) to customers using the entire Renesas AR Line MCU. Renesas RA customers will now have free access to Cyberon’s continuous command-based VUI toolchain, allowing them to add voice recognition to a variety of endpoint applications in home appliances, building automation, industrial automation, portable devices and many more.

Speech recognition is growing rapidly around the world, driven by the explosion of IoT applications and the COVID-19 pandemic. Cyberon’s proven voice recognition technology has been adopted in millions of devices worldwide.

Renesas provides a voice reference hardware platform to enable rapid prototyping and development of voice interfaces. The new hardware platform enables local speech recognition without a network connection using Cyberon’s Dspotter solution. DSpotter’s phoneme-based modeling approach enables rapid customization of commands with only text input, eliminating the need for massive voice data collection and thus reducing cost and development time. DSpotter supports over 40 global languages, enabling customers to adopt voice technology on in-vehicle applications worldwide. This Voice User Interface (VUI) solution demonstrates how easy it is to control a system with a simple voice command interface without extensive coding experience or in-house expertise.

“Customers in multiple segments are looking for help to quickly add reliable voice commands to their products,” said Mohammed Dogar, Vice President of Global Business Development and Ecosystem in Renesas’ IoT and Infrastructure Business Unit. “Our partnership with Cyberon gives them access to proven voice technology across our entire line of RA microcontrollers, from entry-level to full-featured devices.”

“We are honored to collaborate with Renesas to simplify the development of in-vehicle speech recognition functions,” said Alex Liou, Vice President of Cyberon’s Embedded Solutions BU. “Cyberon’s DSpotter algorithm meets various market requirements in terms of cost and performance. The combination of DSpotter and Renesas’ advanced MCU technology enables customers to develop high-performance, reliable and cost-effective products in a timely manner. ”

Key Features of Renesas Voice UI Reference Solution

  • Free access to the DSpotter toolchain
