What if I stutter? I stammer when I say the first word, and sometimes I don't stammer when I adjust my breathing. For example, I stammer at the first word of a sentence and then repeat it.

Stuttering at the first word of a sentence may be that you are nervous and can only overcome it slowly by yourself. Another reason is that you are impatient. You can pay attention to this point in future speeches. Don't be so hasty every time you speak, practice speaking slowly, and you will be basically fine when you get used to it. Finally, there is a particularly good way, but you have to suffer. Pick up a relatively clean stone by the river and put it in your mouth. You can persist in speaking for a long time, stuttering, speaking clarity and speaking speed can all be exercised, but it is too bitter to connect, and your mouth will even be worn out, but as long as you persist, it will definitely have an effect. I have such an example around me.
