Ugh I hate voice training so much but after yesterday's breakdown while trying and getting two "voice analysis" results showing "0% female, 92% male" I decided to watch some videos I've seen recommended, and honestly YuukoEX was the one that helped me the most because I feel like I can try to emulate her voice better than others I've heard.
After spending yesterday on exercises and trying to figure out various muscles around my throat, I managed this: 
It's not much, but it's an improvement!
Also, I'm trying eye liner today! It's a little smudged in one or two spots, but it makes a HUGE difference in my own perception! I even took a face selfie! On purpose!! (for myself I am not nearly confident enough to post lol)
So if you need the reminder, I guess here it is!
I know dysphoria, but not for voice. I didn't even realize voice training was a thing until after I started HRT. I'm really kind of embarrassed that I could've overlooked such an obvious thing for so many years. Rather than dysphoria I had something more like anxiety or terror with the realization that I hadn't considered such a monumental task. I had a deep hillbilly voice. How could that possibly ever change? However, once I started watching some videos and getting the basics it all started to click. I believe singing helps a lot too.
Women (well, feminine voices) tend to enunciate more clearly than men. Your partner may have an easier time deciphering your voice on that account. Showing them that video of AlsoAshley I posted earlier may also allay your partners fears.
I've told myself that I'd flip masculine if I ever felt uneasy around someone, but so far I've only kinda bent masculine. Granted, I'm reclusive so I don't interact with many others. People often change or at least bend their voice and accent to accommodate others, sometimes unknowingly. I've heard people come back from a week long trip in the southern US with a tinge of southern accent. In fact, I've read that vocal fry (from females, in some instances) is an attempt at emulating a deeper voice to fit in with the boys or gain respect.
