Dear Prudence,
I am a teacher at a small community college. I strongly suspect that one of my new students this semester is a trans woman. My problem is that I'm a voice teacher. If I’m right, her larynx has been affected by testosterone, and is functionally male. Even if she’s taking female hormones, the voice changes that puberty brings are permanent. For example, she will be reaching her high notes in falsetto, which requires slightly different technique from that used by a cis woman singing in head voice. But even using the word "falsetto" to describe her high notes seems insulting to me, with its implication that she's using a "false" voice. I can't think of a good way to initiate a conversation about this, but avoiding the issue may compromise how much I can help her sing better. Can I go to my supervisor for advice without violating her privacy? And, dear God, what if I'm wrong?
