Explore psychological factors
When the topic is controversial or needs explanation, you are more likely to speak faster. Even if you are confident about the content, you will speak quickly and can't control yourself. There may be some psychological factors behind this. You can explore your own psychology and find the direction of improvement.
Respect each other's feelings
You can't win recognition if you speak loudly and quickly. When you shoot someone with words, you may ignore their feelings. This is not only disrespectful, but also insincere or dissatisfied. Therefore, in life, every time you talk to someone, remind yourself to control your voice and speed.
Change your habits slowly.
Controlling your voice and speaking speed is a process that needs long-term persistence. Every time you talk to someone, remind yourself to control your voice and speed, and you will gradually change this habit. At the same time, you can also seek the help of professionals, such as attending voice training.
