ESP32 Realtime Voice Relay
Push to talk through the wand.
Hold the GPIO48 button on the wand to capture speech. The relay sends that turn to OpenAI Realtime, waits for the spoken reply, then plays the response here in the browser.
Assistant Buffer
0 ms
Small buffer is good. Large spikes mean the model reply is arriving unevenly.
