Watch the demonstration video below to learn more about the Raspberry Pi Amazon’s Alexa interface that allows you to access the service using third-party week word engine.
The Matrix Voice development board designed to help you easily build sound driven behaviours and interfaces is now available to purchase priced at $55. Offering an radial array of 8 MEMS microphones connected to a Xilinx Spartan6 FPGA and 64 MBytes SDRAM with 18 RGBW LED’s and 64 GPIO pins. If you are interested an ESP32 Wi-Fi / BT enabled 32 bit microcontroller version is also available, more information is available from the matrix.one website, via the link below.
For a guide with full instructions on how to set up your Matrix Voice board with your Raspberry Pi mini PC jump over to the awesome Hackster.io website where the Matrix Lab team take you through the process step-by-step. Demonstrating how to access and test AVS using our Java sample app running on your Raspberry Pi. As well as a Node.js server, and a third-party wake word engine using MATRIX mic array. The instructions also provide information on how to use the Node.js server to obtain a Login with Amazon (LWA) authorisation code by visiting a website using your Raspberry Pi’s web browser.
