Company My NXP MCU-based Solution for Local Voice Control Follow MCU-based Solution for Local Voice Control Turnkey i.MX RT solution for Offline Voice Control Overview Specifications Buy Design Resources Get Help Low Latency Turnkey Solution Low BOM Cost Compact Design <1 second fast response times Easy integration into any MCU based application Reduced by over 50% compared to MPU implementations Ultra-small form factor boards - 30 x 40 mm Full Software Capabilities Far-field audio front end Automatic Speech Recognition (ASR) engine Overview PRE-PRODUCTION NXP's 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.
