The Alexa voice service solution development board based on i.MX RT106A is now available for order!

NXP's MCU solution for Amazon Alexa Voice Service (AVS) uses the i.MX RT106A, allowing developers to quickly and easily add Alexa voice assistant capabilities to their products. This ultra-small turnkey hardware design is fully integrated with Amazon-qualified software to provide an out-of-the-box AVS experience. Currently, a number of intelligent voice recognition products based on this solution have been released on Amazon's official website.

The solution is based on the i.MX RT106A in NXP's i.MX RT crossover platform , with a total system cost of less than half of a microprocessor-based solution. In addition, the solution also includes the TFA9894D smart audio amplifier and an optional A71CH security element, and has been accepted by OEMs developing a variety of industrial and consumer products.
