Your best voice is clear, intelligible and effortless. You want people to listen to what you say, not listen to your voice. When you are making a speech, you will feel more confident if you do this exercise about 30 minutes before. Actors love it.
*Slide your tongue, flatly, out of your mouth so it rests on your lower lip. Keep it there as you speak you first one or two sentences. Use your lips so that you can be understood, (you just sound very strange and it is also quite a big effort.) Make sure you don’t push your head forward and that you continue to breathe low. Speak with strong meaning and intention so that you don’t sound like a robot. I should be able to follow you as you do this.
*Then, let the tongue slide back into the bottom of your mouth (where it wants to be) and repeat those same sentences. You will find that, because you have stretched the muscles at the back of the tongue, the tongue is happier, faster, more specific in its movements. You
will feel that it is just so easy to say the words. As Shakespeare said your words will be …..trippingly on the tongue.
Try it and let me know.
