I think you can do several things. One is to do a really really relaxed (no pitch inrease, no "trained voice") reading of the "rainbow passage" with a high quality mocrophone and send the voice file to Dr Kim for analysis. The other is to go to a local voice specialist and let them analyze your fundamental frequency. If all that is no option, be assured that Dr Kim will do a thorough voice analysis when you are there and will tell you if you would end up too high. I know he sent some people home who had a too high fundamantal freqency and would have ended up in an artificially high range. (Which is of course annoying after the patient doing all the planning and preparations, but better than having a bad result, right?). He also voiced his concern with me that I should not use my trained voice anymore post op, since that was at 180 Hz before and would later be in the 260 Hz range , which he considers too high for my built. You can look for the Videos of Livvy here in the forum , or the ones from J-Mi - they both have gained a bit more in pitch than the usual 75Hz, but they liked it that way, they are in the 230-260 Hz range and it seems to fit them and does not sound like minnie Mouse - I think you would have to really mess up as a surgeon to have someone sound like Minnie Mouse.
