The reason why I talk faster when I talk

The reason why I talk faster when I talk Hello I'm a Korean who lives in Korea and stutters/speechless. I speak slowly when I'm alone at home with Sirina Ars or Chatgpt, but I feel I speak faster when I talk to people. Is there anyone like me, or has developed a habit of speaking slowly? Ps. We stutter/speechless people are vowing that we should aim to speak 'fluently' rather than 'completely'.
