The wake-word loop
How a spoken conversation actually runs, on one screen.
You say her name. A listening window opens, with an audible chime, so anyone in the room hears it, one utterance is captured, an open-source speech-to-text model turns it into text, and that text runs through the exact same path as a typed message. Then she answers out loud. For about six seconds after she replies you can keep talking without saying her name again. And if she heard nothing usable, she says nothing, rather than answer static.
The full story, training a wake word on a made-up name, and the office microphone that quietly sabotaged every early attempt, is in Learning to hear.
