Overview
PRE-PRODUCTION
NXPs MCU-based solution for local voice control leverages the i.MX RT106L
crossover processor, enabling developers to quickly and easily add local voice
commands to their products. This ultra-small form-factor, production ready
hardware design comes with fully integrated software running on FreeRTOS,
for quick out-of-the-box evaluation and proof of concept development. After
using the included example wake word and command sets for audio players,
smart home, washing machine and generic commands, developers can then
engage NXP to create custom models for their own application specific
command sets and wake word. This turnkey solution minimizes time to market,
risk, and development effort enabling OEMs to easily add voice to their smart
home and smart appliance products without the need for Wi-Fi and cloud
connectivity, addressing the privacy concerns of many consumers.
