MCU-LOCAL2-VOICE

Roll over image to zoom in

NXP's EdgeReady MCU-based solution for offline local voice control, leverages the i.MX RT crossover MCU, enabling developers to quickly and easily add voice assistant capabilities to their products. This i.MX RT106S based turnkey solution includes a development kit (SLN-LOCAL2-IOT) with fully integrated software running on FreeRTOS, for quick out-of-the-box evaluation and proof of concept development. The BOM cost optimized reference design and production ready SDK minimizes time to market, risk, and development effort, enabling OEMs to easily add voice to their smart home, smart appliance, smart building and smart industrial products, without the need for Wi-Fi or cloud connectivity, addressing the privacy concerns of many consumers. This second generation local voice solution had a Windows™ based tool enabling developers to create speech models for over one hundred custom commands and multiple wake words from text input, with support for over forty languages.
