I've been on T far longer than some of my friends, and yet, while they all pass on the phone and in person at least 80% of the time, never once have I passed on the phone. My voice is laughably high. My vocal range is significantly smaller than it was pre-T: from F4 to A3, and everything in between is shaky, weak, and feels trapped in my throat. My external appearance has changed enough that I an gendered correctly most of them time, but my voice has not dropped at all, and from what I've read, is even higher than the standard female range. I've been taking a standard injected dosage and my T levels are normal. I have become a virtual mute in public because I am so embarrassed about my voice (picture a hairy hobbit with the voice of a castrato). All the men (and women) in my family have reasonably deep and resonant voices. My doctor pretty much just shrugged his shoulders when I mentioned it and said that male voices are diverse, but I call BS-- I'm in a range that is consistently taken for female. What is wrong with me? 

• Will my voice ever change?
• Is there surgery to change it?
• Has anyone else experienced this?

Sorry to hear you're not happy with trt results.

You are right, all ftm's I have spoken to had amazing results. There voice feminisation surgery for mtf's. Maybe you should look if same surgery exists for ftm's that would allow them to attain a more masculinised voice?

Also, voice passing is not always about pitch. It's also about the intonation and pattern of your speech. My non-strained voice is 170hz, slightly below the female average range. I pass just fine in the phone with the right speech pattern and elevated voice.

Finally, have you considered consulting with a speech therapist?

You never mentioned how long you had been on T. The voice typically drops multiple times in the initial 2 years, so if you haven't hit that point yet, I wouldn't be too stressed.

I would say consider working with a vocal coach or speech therapist if it is something that bothers you.
