I came across this link on Facebook.

He claims to use a technique that is unique. Does anyone know more about it?

I think so but nothing specific. I was browsing around other websites a few months ago and ran across a report of a voice surgery in that areas of the country missing a few facts. The surgery was preformed while the patient was awake so the voice could be adjusted on the fly. From the account, the surgeon reverse engineered the surgery from a description of a another doctors procedure. The description from your link sounds like the surgery is CTA and that would match with the account that I saw on the other site. As what I saw was old, I don't know if the doctors is doing VFS now or if he is still sticking with CTA alone.

Yeah this definitely sounds like a CTA

Oh great. LOL, well he claims to basically have invented his own method that no one else uses - if its CTA thats pretty much nonsense...

Yes he does the CTA. A girl I watch on YouTube did the surgery with him, she sounds very very good actually. But some of the other samples on his website sounded a bit unnatural and too high....
