SLN-ALEXA-IOT: Alexa Voice Assistant on a MCU

NXP’s MCU-based solution for Amazon's Alexa Voice Service (AVS) Integration for AWS IoT Core leverages the i.MX RT crossover MCU, enabling developers to quickly and easily add Alexa voice assistant capabilities to their products. This ultra-small form-factor, turnkey hardware design comes completely integrated with Amazon qualified software for an out of the box AVS experience.

NXP’s MCU-based AVS solution provides OEMs with a fully integrated, self-contained, software and hardware solution that includes both the MCU and an NXP smart audio amplifier with speaker protection. It comes with all far field audio processing algorithms including noise suppression, echo cancellation, beamforming and barge-in capabilities, to enable use in acoustically difficult environments. Also included is the Amazon Alexa client application and a machine learning inference engine for Alexa wake word identification.
