This is a quack. There is literally no research behind this. I do voice research for a living. Fire your coach and buy this instead until you find a legitimate therapist: https://www.amazon.com/Voice-Book-Trans-Non-Binary-People/dp/1785921282/ref=mp_s_a_1_4?crid=2A6YFDJMTXEU5&keywords=transgender+voice&qid=1649553259&sprefix=transgender+voice%2Caps%2C126&sr=8-4. I personally recommend voice therapists who have a degree in speech-language pathology. They should have M.S. CCC-SLP after their names.
Will repeat what people have said that TransVoiceLessons is great.
Also, if you want to get deeper into the theory of it, The Voice Book for Trans and Non-Binary People is a great text.
If you don't have access to pay for a voice coach/speech language pathologist, and you're confused by internet tutorials and not sure what's right and what's wrong, this is a great book my SLP recommended. It goes in enough depth that the concepts should become clear, but it also is aimed at people in the community rather than doctors and people with masters degrees in the subject, so it's pretty accessible and easy to follow. It was written by professional formally educated speech pathologists so it's easier to put your trust in it, at least for me, compared to internet guides (which can also be useful and helpful but are not for everyone)
https://www.amazon.ca/dp/1785921282/ref=cm_sw_r_cp_apa_i_hHUNFbK1C3FYT?_encoding=UTF8&psc=1 you can change the .ca to .com or whatever your countries amazon page is, if that doesn't work you can search the title on amazon or most major bookstore websites.
I still haven't been able to find much. I had a quick look through my voice book (The Voice Book for Trans and Non-Binary People by Mathews Mills) but it didn't mention tonsils or adenoids specifically.
Awesome, we’ll get there :)
I also had some granulation but overall I expect it to work out. Not going to worry about it until I’m approaching 6 months - so May.
Check out this book - might be a worthwhile read!
Official link where you can purchase a copy
Unfortunately, the other author, Matthew Mills, seems fairly obscure and I can't find anything on them.
Here's the Amazon link if it's within your budget and/or you prefer a physical book.
Ugh, I'm sorry you're not able to get the book in the UK! If you'd be willing to email me, I'll happily see what I can do! Another awesome book to check out is The Voice Book for Trans and Nonbinary People.
For science stuff, I also recommend checking out Zoey Alexandria and Zhea Erose. Suuuuper fabulous science nerdiness. <3

This one. I thought it might help to find one that had options for a neutral voice tone as well.
The most common self-help source I know of is a series on YouTube called Trans-Voice lessons: https://youtube.com/c/TransVoiceLessons
I also found thus book helpful, but incredibly frustrating: The Voice Book for Trans and... https://www.amazon.ca/dp/1785921282?ref=ppx_pop_mob_ap_share
Others on this sub may be able to point you to other resources.
I'm see a speech therapist currently, and almost everything we do is covered in this book! You can get it on Amazon (UK or US) "The Voice Book for Trans and Non-Binary People: A Practical Guide to Creating and Sustaining Authentic Voice and Communication" if the links don't work.
It is HELLA helpful. I struggled with youtube guides (The comparative nature of them made me feel poo), but this book was incredible, I could just sit quietly by myself and work through it.
When I went to my first speech therapy session, she said I made several months worth of progress in a sentence (jumping from in-toning to full on sentences with female mannerisms), so it really showed!
