During my holiday in England, I met a guy with a voice of about my range (I'd guess mid/high alto), but YET he sounded like a guy. There is also a Dutch known person who sings soprano on a professional level, and he's a guy as well. I have never thought he might be a transguy, and I'm pretty sure he isn't. But even though his voice is a lot higher than mine, he sounds more genuinely male (I wouldn't say masculine. But male, yes)
This has probably something to do with intonation, right?
Does anyone have an idea what the differences are, and how to learn them? I know some basic things, like women more often end a sentence on a high note, and have a more variable pitch when speaking, but is there more? And what are the best ways to change such a thing? I don't think about talking, it just happens, like breathing or walking, and changing the way I talk has been proven a difficult challenge. I also don't want to harm my vocal chords, obviously...
