When you are reacting to something that made you angry, does your voice become really high-pitched?(Details if needed.)

One word yup!

Actually, mine goes lower and comes from the diaphragm more. The kids used to call it the voice of God.

^Mine goes lower as well.

The kids used to call it the voice of Satan. (jk)

I get silent. I recommend running away in a zigzag pattern.

I very rarely get angry, and when I do I’ve learned to control it by modulating my voice to be normal.

No, but mine tends to get louder and I have to consciously work on controlling it. If it’s sudden or out-of-the-blue anger, that’s difficult.

Like @smudges I get louder and often a deeper more forceful tone. Men and women both tend to simmer down faster.

I don’t get extremely angry often but I suspect that the voice may go up a half or even a full step in the most extreme.

Mine goes lower and the children tremble even if my voice isn’t raised.

I go low voice, when it’s a measured response.
If I am slighted, I get high voiced, but not violent.
Low voice is bad for me too.
I think I can sound really stupid, during emotional reactions. (Believe it or not.)

All I’m saying is I’ve learned to be more careful with low-pitched, growly people. That’s a danger sign to me.
Your pitch can reflect blood pressure believe it or not, so angry low pitches means they’re the more calm, logical opponents.
