RFID-controlled musicplayer powered by ESP32
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.
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.
Combining esp32 Painlessmesh, i2s audio, SD card samples, and modular triggers
Basic DX9-inspired FM synth Arduino Library for Raspberry Pico RP2040 and RP2350.
ESP32 application to change a voice to be eg stormtrooper or dalek sounding, either in real time for cosplay or as a recording. Recordings can be downloaded to the browser as a WAV file for playback on a media player

Bilateral Sound Reactive Prism-Like Light Display using an Arduino Nano ESP32 and an inmp441 Mic
An example of recording audio onto a MicroSD card, using an INMP441 microphone and a XIAO ESP32-C3
library for transmitting data over audio waves using the ESP32 microcontroller
I2S helper class for ESP32 family. Makes I2S Audio really easy.
🔊 An Arduino sketch for ESP32-based MUSE Luxe board that enables network audio streaming via MQTT control.
AI-Waifu is an IoT voice assistant developed for the ECL-108 IoT Workshop. It uses two ESP32 DevKit boards communicating via UART to capture voice input with an INMP441 MEMS microphone and produce speech output through a MAX98357A I2S amplifier. The Google TTS API generates responses in a Japanese female voice.
Proof of concept for dual core sound synthesis via i2s
A simple MEMS I2S microphone and audio processing library for ESP32.
