While I’m sure that exists, it does not in the numbers I have noticed, nor in the “low speakers” I know personally. As I’ve said, people (outside of NYC) are trained to be polite and speak softly, but rarely trained to speak loudly when appropriate.
My son became Senior Patrol Leader (top Boy Scout, Sgt Major) of his troop at the unusually young age of 13, and had to learn to use his still changing voice to get attention and be obeyed because everything is delegated through the SPL. Squeaking at the boys didn’t work, and he was too small to get natural authority of size. He had to learn to control and project his voice, not unlike many women have had to, including my wife as I described upthread. Nothing is natural, not fry, uptalk, or authority. It’s learned.
