Dadlexa is a homemade smart speaker that records a child's question, sends the audio to the father's phone, and plays back the father's recorded reply. It behaves like a commercial voice assistant when activated, but the intelligence answering general questions is the father himself rather than AI.

The device detects its wake phrase, records the question, and sends it through Telegram. When the father replies with a voice message, the device downloads and plays it. Music commands can also play files stored locally on the device. It was created by Sean Clark.
