How not to sound weird when talking to authority?

Weird is mostly only the way you are feeling yourself about the situation when talking to authorities. Calm down before your talk with them and keep telling yourself that they are only people too. They might have been in the same situation you are in right now and can understand where you are coming from. If it's a teacher you are feeling uncomfortable talking about, remember they have been a student at one point in their lives. Bosses at work also haven't been bosses all their life.

To not sound weird you can talk to an authority figure like you talk to anyone else. Just remember to be respectful.

just remember people in authority are still regular people like you and i. its natural to be nervous around people your not familiar with. just be yourself.

Speak with confidence and believe the truth in what you are speaking. Be proud of the words you are willing to share.

Don't talk too much and be careful with your wording. It's not a problem to show you're nervous, so don't worry about it and just try your best to look them in the eye, and express all you have to say with the best confidence you can show.

Talking to authority may be a challenge sometimes, particularly if you're nervous, either because you did something you should not have done or you just aren't certain of that. Take a deep breath and calm down, relax. Also talk slow, avoiding thus to say things that may be unecessary or unhelpful to yourself.

It is important ti be humble while talking to authority, but at the same time we need to be confident. Whatever that it is we are talking about, we should have as much information on that topic as possible, which can boost up our confidence.

Be very factual with authority, try not to stutter or look like your scared. Give them a look of the best you.

Relax. If you get anxious and try to rehearse everything you are trying to say before you say it to them it will not sound genuine. Get out of your head and just be your charming self because they may have some authority but they are still a person.

If you mean the way your voice changes when talking to strangers/when you uncomfortable, calm yourself down and think about what you would say if they asked a certain question. Speak clearly and slower than usual. They should not mind so long you are respectful and cooperative.
