“I can often tell just by the tone of someone’s voice their ethnicity”
Musicians can do this also and it is not hard so I will back you on this. There is a certain “Timbre” to the vocal chords of different races. Very rarely is this not the case, Charley Pride had many people fooled for awhile back in the day.
Charley Pride was one of my favorites back then. He died Dec. 2020 of COVID. Breaks my heart. I was born in a town on the Mississippi River, so his song about the river meant a lot.
