I don’t know I shout

I have this problem too, it mainly only happens when I am excited, and am trying to communicate something with intense emotion -- "excited", not in the pleasurable sense, like this makes me happy, although that can happen too, but more physiological (increased intensity - adrenaline, cortisol, stress).

There is a gradual acceleration, in that I can start speaking normally, but then the faster I speak the louder I get.

Therefore, the way to prevent or manage this is to be aware of those moments when your son is eager to say something (it will usually show in his body language), then point this out to him and make him pause for a second, then speak -- he has to learn to adjust his voice level BEFORE speaking to people -- I emphasis before, because he has to make the connection himself that:

1. Before I speak, I need to be calm

2. When I speak, I need to talk slowly

3. People will be more receptive, when talking slowly (improves his understanding of empathy)

At age 18 he is likely too old to be using flash cards, but because we have difficulty in reading body language and knowing what is and isn't appropriate, it may help him to use visual cues to learn to associate situations with actions, and actions with apprioriate voice level.

It may also help by using a physical hand gesture to signify that A) he is too loud B) which means he needs to lower his voice AND speak slowly (making him calmer) - the two must be done together in order to ease their anxiety and excitement.

A hand gesture that comes to mind is pointing and tapping your ear. Ear is symbolically associated with hearing so it's symantically correct. It also won't get you strange looks in public.
