ESP32 Speech-to-Text using Wit.ai In this project, we’ll be learning how to build an ESP32 Speech to Text system using an ESP32 development board. We’ll use an I2S MIC to record speech and an OLED display to display the converted text. In addition to the display, the text will also appear in the serial monitor. Since ESP32 cannot run a Speech recognition model locally due to its hardware… |
