Many transpeople have trouble being misgendered over the phone, even when being gendered correctly in face-to-face conversations. This is primarily because the listener doesn’t have the added benefit of seeing the person’s appearance. Below are some recommendations for strategically using your best voice/speech skills when talking on the phone to people unfamiliar to you.
a. Start by saying, or even spelling, your name very clearly whenever appropriate.
b. Nail the first sentence. Your listener will likely make any determination regarding your overall identity within the first few words they hear you speak. Aim your pitch slightly higher or lower than you usually do.
c. Speak slowly.
d. Hum or lip trill or practice the conversation beforehand or when you are on hold.
e. Practice your best phone voice by leaving messages for a friend or recording fake messages on your own phone.
