NXP's voice intelligent technology (VIT) library provides voice UI enablement with always-on wake word detection and local commands. It is based on state-of-the-art deep learning and speech recognition technologies and provides a complete audio front end / wake word / voice commands solution. VIT is available royalty-free on several platforms: including those based on Arm® Cortex®-M7 and M33, Cadence Xtensa® HiFi 4 and Fusion F1 cores.
The VIT library is a free, fully comprehensive voice control software package for use with supported NXP devices and is delivered as a ready-to-use library in the MCUXpresso SDK. VIT enables customer-defined wake word and commands using online tools.
NXP's VIT is well-supported and free-to-deploy to developers looking for a shorter time to market for voice control applications.
