In answer to the question within your post, yes, I think it'd be nice to acknowledge your transman friend's vocal changes - but obviously in a "wow, your voice sounds really good" rather than "ewww, your voice sounds weird" way, if at all possible. Vocal pitch is one of the first things to change after commencing testosterone supplements, usually starting to feel subjectively 'scratchy' after around six weeks and thereafter sounding progressively deeper. I'm willing to bet he's keeping a diary of these changes, and is thrilled every time someone comments positively, or 'reads' him as male over the 'phone.
Put it this way: very soon, there'll be other changes - increased appetite, unpredictable sex drive, mood swings (especially, this being a second puberty, irritability), clitoral enlargement, skin coarsening, muscle thickening, growth of body and facial hair, (possible) male pattern baldness, acne - some of which will be very visible indeed. You might as well start acknowledging his transition now... |
