Arduino Talkie Speech Amplifier Shield for ESP32
Give your robots a voice with the Speech Amplifier and the library Talkie. Squeeze the tiny Amplifier shield into any ESP32 small device. See this Instructable for the Talking Penguin project.
Description Mounting the Amplifier shield on top of the TinyPICO avoids all mess with cables. With ESP32 WiFi and over-the-air (OTA), there is a possibility to update the code (firmware) without disassembling the robot. The amplifier has a built-in voice filter to limit unnecessary high frequencies. Use the second DAC to control the Arduino Talkie Speech Amplifier's volume digitally.
Add the Amplifier shield board to the ESP82 TinyPICO so that the screw terminal is above the USB connector. Next, connect an 8-32 Ohm speaker element to the screw terminal.
Please, see the Arduino library installation documentation and how to install the Arduino library.
Try one of the sketches in the
example directory, for example, my
goodmorning.ino. Then, use Over-The-Air (OTA) to update your ESP32 TinyPICO robot remotely. See the example
updaterobotOTA for a start.
Other usages than robotics may be a customized keyboard pad with voice reply for entering a building, adding sounds to a game, which was original use in the 70s/or early 80s, or a keyboard trainer.
The Arduino Talkie Speech Amplifier uses Texas Instrument's LM4875 chip and amplifies the DAC signal from ESP32 TinyPICO GPIO25.
GPIO26 can be either connected to 3.3V for maximum gain/speaker volume or digitally controlled by the second DAC in the ESP32.
Arduino Talkie Library
Let your robot use your created word or sentences or the pre-defined 1200+ sounds and phrases from the Talkie library. The fun begins when using the Talkie library.
