How do you make it reliably listen to your conversations give that you may move your hands around, wear a shirt or jacket covering it, have them below a table, etc?

not sure. however, my best guess would be to have the best mic(s) on the market for a wearable, so that it can pick up on voice crisply, and then just go on about your day and see what context the AI extracts throughout the day.
