Espressif ESP32-S3-BOX-3 - The all-in-one dev puck Home Assistant's own voice docs point to

Quick verdict

The all-in-one dev puck Home Assistant's own voice docs point to: dual mics, speaker and a 2.4-inch touchscreen with on-device wake word. Wake word runs on-device and the Assist pipeline stays on your HA server via ESPHome. Just note: Setup can be fiddly vs a finished product.
