Tatlock turns take 10-25s, which is a long silence after a request. Speak a canned "Let me check on that for you, sir" immediately (synthesized once and cached), then re-assert the thinking state so the device keeps its effort-face spinner up until the real reply arrives. On the device, guard the playback-done handler so the filler audio finishing doesn't drop the spinner back to idle.
