Steps To Stop Nervous Chattering
Take a deep breath and relax before you speak. The tension from nervousness can be somewhat alleviated if you just relax before you start talking.
Ask a friend or significant other to give you a signal when you are nervously chattering away. Sometimes, people just do not realize they are chattering even though they are aware it can be a problem for them.
Stay away from conversation topics that make you nervous. There are certain subjects that make some people nervous. If these topics surface, either walk away or change the subject as soon as possible.
Put a mental limit on the number of words you say at a time. This can be difficult, but when you are talking, make a mental note that you are going to say no more than 10 words. The specific number does not matter. What matters is that you placing a finite boundary on the uttered words. Then count them as you speak and stop when you get near the maximum. This will force you slow down your speech and talk at a normal pace.
Practice talking in front of a mirror or around close friends. If you concentrate on your speech pattern closely, you can eventually slow down the nervous chatter to a manageable pace.
