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.

Measure volume of noise using ESP32 and Adafruit I2S Microphone (SPH0645)

Two state sensor (On/Off) reacting on sound levels measured by I2S microphones ( SPH0645LM4 or INMP441 )

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.

Records audio on an ESP8266 from an I2S microphone and serves it as WAV data over a TCP stream
