With a month left in the Indiegogo funding period, the MATRIX Voice open-source voice platform campaign stands at 289% of its modest $5000 funding goal. MATRIX Voice is the third crowdfunding project by MATRIX Labs, based on Miami, Florida. The MATRIX Voice platform is a 3.14-inch circular circuit board capable of continuous voice recognition and compatible with the latest voice-based, cognitive cloud-based services including Microsoft Cognitive Service, Amazon Alexa Voice Service, Google Speech API, Wit.ai, and Houndify. The MATRIX Voice board, based on a Xilinx Spartan-6 LX4 FPGA, is designed to plug directly onto a low-cost Raspberry Pi single-board computer or it can be operated as a standalone board. You can get one of these boards, due to be shipped in May, for as little as $45—if you’re quick. (Already, 61 of the 230 early-bird special-price boards are pledged.)
Here’s a photo of the MATRIX Voice board:
This image of the top of the MATRIX Voice board shows the locations for the seven rear-mounted MEMS microphones, seven RGB LEDs, and the Spartan-6 FPGA. The bottom of the board includes a 64Mbit SDRAM and a connector for the Raspberry Pi board.
Because this is the latest in a series of developer boards from MATRIX Labs (see last year’s project: “$99 FPGA-based Vision and Sensor Hub Dev Board for Raspberry Pi on Indiegogo—but only for the next two days!”), there’s already a sophisticated, layered software stack for the MATRIX Voice platform that include a HAL (Hardware Abstraction Layer) with the FPGA code and C++ library, an intermediate layer with a streaming interface for the sensors and vision libraries (for the Raspberry Pi camera), and a top layer with the MATRIX OS and high-level APIs. Here’s a diagram of the software stack:
And now, who better to describe this project than the originators:
