Is it okay to compliment a transwoman's voice?

I have been developing a huge crush on one of my friends. One out of many things I am attracted to her is her beautiful voice with a bit of thickness. Sometimes when we chat face to face or voice chat I get so turned on by her voice and the way she talks.

I know that some transwomen may be self conscious about their voice or they train to have a higher pitch. But I like her the way she is and I find her voice feminine af anyway. Is it okay if I tell her or transwomen in general that their voice sound great?
