NXP Semiconductors has added a natural language engine to its microcontrollers to provide ‘speech to intent’ for edge devices

The NXP VIT Speech to Intent engine for local voice control using natural language processing and is designed to rival cloud-based systems such as ChatGPT without the need for a connection and by keeping all the data on the system. This also improves the latency and reduces the overall device power consumption.

The engine is part of NXP’s Voice Intelligent Technology (VIT) software suite and allows people to speak naturally to smart machines across IoT, industrial and automotive applications, rather than memorize precise commands or phrases to operate the devices. 

The software currently supports English language interactions, with support for Mandarin coming later this year. Additional support is planned for Spanish, German, Korean, French and Japanese in 2024.

NXP sees voice becoming a key interface for smart home, smart factory or smart city applications with ‘voice first’ devices. These currently require precise phrasing to execute the desired action or cloud connections to translate the user’s speech into device actions. Natural language understanding with VIT Speech to Intent allows devices to understand users’ intent, without requiring exact phrasing or cloud connectivity.

The VIT Speech to Intent engine is available and suitable for use on NXP MCUs and MPUs with ARM Cortex M7, M33 and A53 cores, including the i.MX RT Crossover MCUs and RW61x MCUs and i.MX 8M Mini, i.MX 8M Plus, and i.MX 9x applications processors.

“As we move towards smart devices that can better anticipate and automate based on our needs, particularly in the smart home, voice has emerged as one of the preferred ways to communicate our preferences to devices,” said Rafael Sotomayor, Executive Vice President and General Manager, Secure Connected Edge, NXP.

“VIT Speech to Intent allows people to interact with smart devices seamlessly, without needing to rely on specific keywords, delivering convenience and ease of use, reducing complexity and alleviating user frustration. This further enables the transition from a smart home to an autonomous one.”  

VIT is comprised of an always-on Wake Word engine, a Voice Command engine, and a Speech to Intent engine. The free VIT Wake Word and Voice Command Engines are available through the MCUXpresso SDK and an online model tool allows developers to start developing with NXP’s Voice Intelligent Technology Portfolio immediately.
