Observe your breathing.
Breath into your stomach expands.
Relax as you exhale.

When people speak to you.
Before you reply, breath in.
Relax when you speak.

u dont... control it.. just speak slowly.. and calmly.. let the other party have their own speed..

“If you are depressed you are living in the past.
If you are anxious you are living in the future.
If you are at peace you are living in the present.”
― Lao Tzu

Tachylalia? fairly unusual to hear about this kind of complaint. you shud ask the occ therapist if got recommendation for a formal speech therapist instead.
