@TropDePieds@mastodon.lol voice is really hard to get started on in my experience but you can definitely get it to a point of "good enough, way less dysphoria" without a huge commitment.

I found the combination of this book https://www.goodreads.com/book/show/34520454-the-voice-book-for-trans-and-non-binary-people and a voice analyser app to be easy for a quick but consistent routine.
