Overview
SpeechRecogHardware is an open-source printed circuit board by AiwendilsCode, from the AiwendilsCode/Arduino-speech-commands-recognition repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 65 × 100 mm with 36 parts on 41 nets, routed with 192 tracks and 2 vias.
Its parts include 12 resistors, 11 diodes, 5 connectors and 1 capacitor. It belongs with the AVR (ATmega, ATtiny) boards of this library.
README
README.mdArduino speech commands recognition
Arduino speech commands recognition is project in which I tried teach Arduino Nano recognizing words or commands using neural network. This project is inspirated by another speech commands recognition project by Peter Balch. Difference between mine and Balch's project is that I used different algorithm for recognizing words.

Questions
How big is the SpeechRecogHardware PCB?
It measures 65 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SpeechRecogHardware use?
36 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the SpeechRecogHardware KiCad files?
From the AiwendilsCode/Arduino-speech-commands-recognition repository on GitHub, at the commit this page was made from: the board is hardware/PCB/speechRecogHardware.kicad_pcb and its schematic hardware/PCB/speechRecogHardware.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SpeechRecogHardware design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
