A voice and audio focused development board with an 8 microphone array that enables you to create your own audio driven applications or use voice assistants such as Amazon Alexa, Google Assistant, PocketSphinx, etc.
MATRIX Voice is a development board for building sound driven behaviors and interfaces. MATRIX Voice is an open-source voice recognition consisting of a 3.14″ diameter development board with an onboard ESP32 WiFi microcontroller, a radial array of 7 MEMS microphones, a Xilinx Spartan6 FPGA with 64 Mbit SDRAM, 18 RGBW LEDs, and 64 GPIO pins. The Matrix Voice provides developers the opportunity to integrate custom voice & hardware-accelerated machine learning technology right onto the silicon. The energy-efficient ESP32 allows for operation without an attached SBC and can be programmed with the Arduino IDE.
It makes it perfect for battery-powered deployment and industrial IoT applications. MATRIX Voice was built with a mission to give every maker, tinkerer, and developer around the world a complete, affordable, and user-friendly tool for simple to complex Internet of Things (IoT) voice app creation.
