I’ve had people use rtx voice on discord and spam me with noise. I think it needs some work but is a great idea.
On a related note, I started using Nvidia's RTX Voice a few weeks back; I've never found anything better to remove background noise (and the noise of my mechanical keyboard). That includes some very expensive hardware solutions. It's incredible.
