Master's Thesis: "Acoustic Identification of Wood-Boring Insects with TinyML".
This is my API for digital signal processing (DSP) with ARM Cortex®-M processor using CMSIS DSP software library.
This project aims to implement a speech command recognition system on an STM32F407 Discovery board. The system is designed to predict two keywords, "yes" and "no," while classifying other sounds as "noise." It utilizes embedded audio processing and deep learning techniques to achieve efficient speech recognition on a microcontroller platform.
Features firmware for identifying and controlling a second order plant. It uses the LMS algorithm to estimate the plant parameters, and a standard PID controller implementation to improve the step response of the system.
