For those that don't mind the blending aspect, that is very admirable and I'm glad you have the amount of inner strength to disregard those concerns; however, the voice aspect does tend to be a sensitive spot for many transitioners. Not only because it can lead to someone feeling outed but because a deeper or masculine voice can be dysphoria inducing. Just like many women want to have a feminine appearance for themselves, they want a feminine overall presentation. It's about finding what works for each person and what their own individual comfort levels and needs are. And for better or worse, voice is one of those critical clues that can prevent passing if not fine tuned. Of course, passing isn't the be all and end all, and honestly I wish I could get over my crutch on this issue and am working on it, but it is important to many people. I know I definitely want to have a "female" sounding voice in the end as it is part of my dysphoria.
In any case, I just hope voice isn't the only concern here because with hard work it can be dealt with. It just takes time and can be very frustrating, at least that's been the case with me. If that doesn't work, there are surgical procedures, though I would always suggest seeing if you can get away with it naturally. I've seen plenty of people do just that with great results.
