I’ve logged temperature fluctuations in a few rooms and noted that people often pause right after a drop of a degree or two. The data show a lag of about 15 seconds before someone speaks, but it’s not a deterministic cue—just a probabilistic hint. If you want to map it, start by recording ambient temp, microphone levels, and the exact timestamp of each utterance. Then run a simple cross‑correlation; that’s where the pattern might emerge, if it does at all.
