Anything Raspberry Pi related catches the eyes and ears of developers, tinkerers, and nerds alike. Since its formation, the Pi has truly opened up the world of computing opportunities on a smaller level than ever before. Besides all the wonderful things the Raspberry Pi can do, how about we discuss what the Matrix voice tool can do. Basically, it can turn your Raspberry Pi into an Amazon Echo, or, the equivalent of it.


The Matrix Voice dev board works either with the Raspberry Pi, or your Stand-alone ESP32 (Wi-Fi/BT/MCU) to create voice-control applications at a very low price point. More explicitly, Matrix Voice works using an array of 7 MEMS mics, connected via an Xilinx Spartan6 FPGA+64 Mbit SDRAM. Voice recognition is also featured thanks to the array of microphones, which, once triggered, includes services from Microsoft Cognitive Service, Amazon Alexa Voice Service, Google Speech API, and more. Hardware wise, there’s a 64 GPIO pin board, which breaks down to 40 pins from the Raspberry Pi, 16 GPIOs and 2 i2cs, and power pins. For tinkerers working on more commercial versions in the IoT world, Matrix Labs offers an optional 2.4GHz Wi-Fi Bluetooth-enabled 32-bit microcontroller version of the device.
