None of my Ts or Pdocs have sounded the same. I'm in the US and have had 8 Ts and 9 Pdocs.

Some have authoritative tones. Some were just simply ***holes

My T talks in her normal voice expect when I'm struggling...tthen she whispers. My Pdoc also talks in a normal voice. She changes her vocabulary more so then tone when I'm struggling. Both are strong women (my Pdoc can be intimidating if you aren't used to her), but both show care via tone. And I don't consider either one creepy.
