NXP Semiconductors SLN-ALEXA-IOT Turnkey Solution for Alexa
NXP Semiconductors SLN-ALEXA-IOT Turnkey Solution for Alexa Voice Service (AVS) is designed to provide OEMs with a fully integrated, self-contained, software and hardware solution for adding Alexa Voice Assistant capabilities to their applications. This ultra-small form-factor hardware design, based on the i.MX RT106A audio crossover processor, comes completely integrated with Amazon-qualified software for an out-of-the-box AVS experience.
The SLN-ALEXA-IOT 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.
i.MX106A Processor
The i.MX RT106A is a solution-specific member of the i.MX RT1060 family of crossover processors, targeting cloud-based embedded voice applications. It features the Arm® Cortex®-M7 core, which operates at speeds up to 600MHz to provide high CPU performance and best real-time response. This i.MX RT106A-based solution enables system designers to easily add voice-control capabilities to a wide variety of smart appliances, smart home, smart retail, and smart industry devices.
Features
- Amazon Alexa-qualified, single MCU Alexa Voice Service implementation
- Based on i.MX RT106A Audio Crossover Processor (Arm Cortex-M7 @600MHz)
- Easy-to-use, BOM-optimized, production-grade, turnkey solution
- Enables products to be Alexa Built-in Certified* at a lower cost than traditional application processor-based implementations
- Brings Alexa to a wider range of cost-sensitive products
*What is the difference between "Alexa Built-in" and "Works with Alexa"?
Devices that have "Alexa Built-in" run the Alexa Voice Service themselves, can accept Alexa voice commands directly, and can control other devices, without the need for a separate Alexa device.
Devices that "Work with Alexa" are compatible with the Alexa Voice Service. These devices can be controlled by commands spoken to other devices with "Alexa Built-in".
