Help enabling Microsoft Neural Voices for SAPI 5?

Hello!

I'm fairly certain this is alright to post here, but if that's not the case, do please let me know and I'll take it down immediately.

I have been trying to use the Natural Voice SAPI adapter to get Microsoft neural voices enabled, with the goal of using them with NVDA. It was working on a previous computer, but that machine is sadly no more. While I'm aware there is an addon floating around somewhere for these voices, it lags and also will not speed up sufficiently for my use case, so I'm trying to get this working. Sadly, I don't exactly remember what I did the last time to make it work.

So far, I've downloaded the voice I'd like to use, extracted it, and placed it inside a folder in my OneDrive simply called Voices. I pointed the adapter there and installed both 32 and 64 bit versions. However, the voice refuses to show up for any programs, or in the control panel.

Any help would be appreciated. Thank you! In case it's helpful, I'm on a Snapdragon processor, which I understand can be a bit different. However, given that an arm version of the adapter exists, I assume this should still work?

Sincerely,
bamboozled!
