You can also increase the sentance for example i wanted to ask " event is cancelled" i changed it to " What i wanted to ask is will event be cancelled" now here the trick is start slow , Speak slowly "what i" now while speaking "wanted to ask" speak it in a Fast tone take a pause for "will event will be cancelled ",let the air go in your mouth and then continue to speak . always take a pause when you think you have stuck up and speak slow so that ull have control over your sentance
