Mute Your Microphone While Typing with Hushboard
It isn't quite the same, but RNNoise is a neural-network based noise reduction aimed at dampening anything that isn't human voice. It works fantastic to me and almost always completely mutes my keyboard. (Sometimes it comes though a bit if I am talking at the same time.)<p>This is easy integrated into Pulseaudio using PulseEffects (<a href="https://github.com/wwmm/pulseeffects" rel="nofollow">https://github.com/wwmm/pulseeffects</a>).<p>(The PulseEffects support is new, I used to use NoiseTorch (<a href="https://github.com/lawl/NoiseTorch" rel="nofollow">https://github.com/lawl/NoiseTorch</a>) which is more dedicated but has a weird UI and some other downsides)
