MCU-Based Solution is Qualified with Alexa Voice Service

NXP Semiconductors has unveiled an MCU based voice control solution qualified with Amazon’s Alexa Voice Service (AVS). This enables original equipment manufacturers (OEMs) to quickly, easily and inexpensively add voice control to their products, giving their customers access to rich voice experiences with Alexa. Built on an NXP i.MX RT crossover platform, this MCU-based AVS solution enables low latency, far-field, “wake word” detection; embeds all necessary digital signal processing capabilities; runs on Amazon FreeRTOS; and includes an Alexa client application.
This MCU-based AVS solution provides OEMs with a self-contained, turnkey offering that enables them to quickly add Alexa to their products. It includes the MCU, the TFA9894D smart audio amplifier, optional A71CH secure element and comes with fully integrated software. It also features noise suppression, echo cancellation, beam forming and barge-in capabilities that enable use in acoustically difficult environments.

NXP offers at its Mougins, Sophia-Antipolis facilities a product testing service for Alexa Built-in products, available to its customers desiring to test their devices before submitting to Amazon for final evaluation. If a customer’s product supports music and/or is far-field enabled and uses a “wake word” to initiate interactions with Alexa, additional testing is required prior to submitting products to Amazon for evaluation. This is where Pro-Support Audio Voice Services helps to complete the self-test checklists.

Arrow Electronics and Conexant Systems Collaborate on Development of Amazon Alexa-Enabled Smart Home Products

Arrow Electronics recently agreed to distribute and source components and provide technical design support for Conexant’s AudioSmart 2-Mic Development Kit for Amazon Alexa Voice Service (AVS). Conexant recently announced a collaboration with Amazon on an AVS-approved AudioSmart 2-Mic Development Kit. Featuring the Conexant AudioSmart CX20921 high-performance hands-free Voice Input Processor and “Alexa” wake word technology, the Conexant AudioSmart 2-Mic Development Kit will help developers and manufacturers quickly and easily build Alexa-enabled products that provide users with an ideal voice experience.Arrow Conexant - kit

The Conexant AVS-approved AudioSmart 2-Mic Development Kit is designed to be easily integrated into any third-party AVS system prototype based on the Raspberry Pi. Its dual-microphone voice processing capability recognizes the “Alexa” wake word and delivers speech requests from anywhere in a room—even in noisy, real-world conditions. It also enables voice barge-in capabilities, allowing users to interrupt their Alexa device when it is playing music or other types of sound.
