Answer:
Positive
Explanation:
If you sound positive people around you will understand your speech better and think you take it seriously, but if you sound negative, then they won't take you seriously and will not understand the point you are trying to make.
But thats just my opinion.
I think it is more effective to sound positive in a public speech because if you are to come off as positive to people during a public speech people will understand your speech better and take you seriously.
