stm32-speech-recognition-and-traduction is a project developed for the Advances in Operating Systems exam at the University of Milan (academic year 2020-2021). It implements a speech recognition and speech-to-text translation system using a pre-trained machine learning model running on the stm32f407vg microcontroller.
Getting started with various ESP32 development boards. Lots of examples.
Code snippets showing how to record I2S audio and store as .wav file on ESP32 with SD card, how to transcribe pre-recorded audio via Deepgram SpeechToText (STT) API, how to generate audio from text via TextToSpeech (TTS) API from OpenAI a/o SpeechGen a/o Google TTS. Triggering ESP32 actions via Voice.
A simple audio player using I2S in ESP-IDF 5.x to play WAV files from an ESP32
I2S transciever implemented in Verilog HDL
Audio visualization based on an M5StickC (ESP32), i2s microphone, FFT and RGB LED strip.

I2S Arduino Library for STM32 Microcontrollers
Touch macropad for HELLDIVERS™ 2
ESP32-based voice device for chatting with multiple custom AI bots. Recording questions with I2S microphone, transcribing via ElevenLabs or Deepgram STT, creating response with Groq or Open AI LLM. TTS audio output with custom AI voices via I2S & speaker. Supporting ongoing dialogues, calling bots ‘by name’, real-time web search via keyword.
