Hi there! I wonder if there are trans voice training programs for Linux-based systems. I see a few recommendations for mobile apps here and there, but I’d very much prefer a free/libre/open-source program that works on my primary devices.
I’ve also been looking into real-time spectrometers, but haven’t had much luck yet. (I’ll shift the blame to PulseAudio)
Vosk-server Vosk-api
Both are Apache-2.0 and the api is available on the AUR (albeit they’re a bit outdated)
also here’s a link to vosk’s models
This might not be exactly what you’re looking for but hopefully it provides another good option for you
