The first thing is to be aware of when your speech is unclear or slurred. Ask others sympathetically to understand what your problem is. People tend to do things more quickly nowadays, and seem to have less patience with others, who may not keep up with their fast pace. This is true even in family settings. Tell people that you are not drunk or have anything wrong with your mental state, just a problem of coordination of your voice.
Check how long people have the time to talk with you, so that you are not disappointed if they leave in the middle of a conversation. When people understand your situation, they will be willing to spend more time in conversation with you. You can help also by:

• being much more deliberate in your speech;
• trying to pronounce your words much more precisely;
• slowing down your normal pace of speech, and
• giving yourself more time by pausing periodically.

Through these means you can maintain a good rhythm, even if you speak much more slowly than you would normally.
Learn to breathe in ways that assist the production of speech –
coordinated breathing in sequence with your speech is crucial.
Don’t try and speak for too long as this could exacerbate the problems with your speech, and both you and your friends may ‘lose the thread’ of what you are saying. After all some of the most memorable or amusing things that we hear are very short and to the point!
