NVIDIA released RTX Voice, a plugin that leverages NVIDIA RTX GPUs and their AI capabilities to remove distracting background noise from your broadcasts, voice chats, and remote video conferencing meetings. NVIDIA has marketed this RTX only, and that does not seem to be the case. 

David Lake from our forums started messing about a bit with the software and discovered it'll work without RTX and even on Windows 7 as well. With a pretty easy mod applied to the installer, Lake was able to remove the RTX / Windows 7 system restrictions. Multiple users have reported on our Guru3D forums, but also Reddit, and Twitter that the mod gets RTX Voice to work even on Pascal, Maxwell, and Fermi hardware. But not for everybody, that also needs to be said.

Likely RTX Voice makes use of a CUDA-based GPGPU code path and not RT/Tensor cores. Instructions on how to mod the RTX Voice installer can be found here, and you do so at your own peril/risk.
