Raising one's voice is a form of communication that involves speaking louder than usual. Yelling is a more extreme form of raising one's voice, and it is often used to express strong emotions such as anger or excitement. Yelling can also be used to get someone's attention or to make a point. In some cases, yelling can be seen as a sign of disrespect or aggression. It is important to remember that raising one's voice should only be done in appropriate situations.
