As human beings,we have the special ability to share our thoughts by talking. We start by forming a thought in our brains. In the brain,this thought is changed into a code called language. Finally,the brain sends a message to the muscles telling them to move and make the right sounds come out. Then the mouth,face,neck,tongue and throw muscles into motion. Sometimes these process doesn't work perfectly though,they might be an interruption,a brake,in the flow of speech. This interruption is called disfluency. Disfluency becomes a speech problem when it gets in the way of everyday talking,and it's noticeable to other people. It can make it hard to get thoughts of. It can also cause a lot of embarrassment or frustration as a person who is talking.
