Amazon Alexa is expanding beyond smart speakers and other tabletop form factors, as the Alexa Voice Service (AVS) pursues resources that enable third-party developers to launch new products to the delight of their customers. Today we introduce an exciting and new delivery on that commitment: The XMOS VocalFusion 4-Mic Dev Kit for AVS–the first reference solution for AVS with a linear mic array qualified for far-field voice capture.
This dev kit brings intelligent voice control to new device types, including smart panels, kitchen appliances, and other wall-mounted and close-to-wall commercial and industrial electronics that benefit from far-field performance in a linear form factor.
The dev kit is based on the XMOS VocalFusion XVF3000 multicore voice processor that boasts advanced voice digital signal processing capability, full duplex acoustic echo cancellation with barge-in, and advanced noise suppression technology including adaptive beamforming.
The dev kit is generally available to developers, OEMs, and ODMs through Digi-Key.
“We’re delighted to work with XMOS as they introduce the first far-field linear mic array AVS solution, making it easier for developers and OEMs to build Alexa-enabled products,” said Priya Abani, Director, Amazon Alexa. “XMOS’ VocalFusion 4-Mic Dev Kit for Amazon AVS will accelerate the deployment of Alexa in deeply embedded systems, new device types, and form-factors, bringing customers more choice of where to access Alexa.”
The dev kit includes a compact array board of four Infineon MEMS microphones, the XVF3000 processor board with I2S serial audio and I2C serial control interfaces, an xTAG debug adaptor, cables, and a stand optimized to hold both boards and a Raspberry Pi Model 3 (sold separately). The xTIMEcomposer software development environment from XMOS provides all the tools needed to program the I/O functionality of the VocalFusion XVF3000 multicore voice processor.
The XMOS VocalFusion 4-Mic Dev Kit for Amazon AVS is also the first dev kit that includes a reference client for Raspberry Pi 3 built using the AVS Device SDK. The AVS Device SDK is designed to enable commercial device makers to get to market faster with Alexa-enabled products.

What Is the Alexa Voice Service?
AVS enables developers to integrate Alexa directly into their products, bringing the convenience of voice control to any connected device. AVS provides developers with access to a suite of resources to quickly and easily build Alexa-enabled products, including APIs, hardware development kits, software development kits, and documentation. Through AVS, device makers can add a new intelligent interface to their products and offer customers access to a growing number of Alexa features, smart home integrations, and skills. Just ask, and Alexa will respond. Visit the AVS Developer Portal to get started.
