@tspivey Also, how does NVDA chunk text it passes to a synth? Even that's not really documented anywhere LOL. I think Kokoro inference would need running in its own thread, so the thread could be killed when we wanted to stop speech rather than generating extra samples, and a knew thread could be started so you could start the new speech quickly, like when someone's pressing down arrow rapidly. But I don't have the time, and I'm not smart enough.
