So i started a new job a couple weeks ago and its going good but i work in a auto motive shop and everyone is required to wear ear plugs because of the noise. Its hard to talk loud enough for people to hear me sometimes and i kind of forgot how to speak properly. my voice is generally low but when i talk loud my voice tends to go high pitched and it sounds like im 5 years younger than i actually am. Any tips to talk loud and confidently?
