Result:
Visualization of MFCC for one sample. 
Training result. 
Hardware & Software 
Microphone: Simple USB microphone is used to get voice input. 
Raspberry Pi: Raspberry Pi 400 kit is used to process the voice and send 
commands to the STM32. It consists of an adapter, microSD card, mouse, and 
keyboard. Python Librosa library and Tensorflow are used through the 
Anaconda Spyder environment to process the sounds and build the model. 
Then this model is given to Raspberry Pi and command detection is performed.
STM32: STM32F is selected to control the components and it is 
programmed with STM32CubeIDE software.
SPI: 
Serial Peripheral Interface is utilized to make communication 
between Raspberry Pi (master) and STM32 (slave).
