A challenge that  a lot of people have during meetings and presentations is speaking too fast. This inevitably leads to the next challenge - not speaking clearly or mumbling: There is just not enough time to fully pronounce all the words. The tragedy is that people only "get" half of what you have to say or even misunderstand you. 
What to do?

• Practice deep breathing techniques to slow you down.
• Speak louder - it is hard to to mumble when you speak loudly enough. 
• Practice your tongue - it is the most flexible organ in the body !

Let me guide you through some exercises to practice the tongue. It is a wonderful way to learn to speak with slower and more clearly. Enjoy!
