Vocal warm ups are essential for effective public speaking.
The benefits are minimizing the possibilities of straining your voice, stumbling over words, forgetting what was coming next, and succumbing to a fit of the nervous jitters.
Vocal warm ups help channel the natural pre-performance adrenalin rush positively. In short, these exercises prepare and center you.
In your lead up to speaking complete all of your stage and prop checks and then aim to set aside a minimum of ten - fifteen minutes for vocal warm ups in a private quiet place before you take the stage.
Pick and mix from the body, breath and voice exercises taking care to work all three areas equally.
You'll find the warm up session
works wonders for focusing, relaxing and settling any nervous tension as well as improving the quality of your delivery.
Stand with your feet a shoulder width apart, breathe in through the nose and bending from the waist allow yourself to flop like a rag doll while breathing out through your mouth. Shake any tension out of your arms, neck, shoulders and allow yourself to literally hang loose. And then breathing in through your nose very gently and slowly bring yourself upright and breathe out through your mouth.
Shake out your arms and hands until you feel them warm and relaxed. Do the same for your legs.
On an in-breath hunch your shoulders as high as your ears and then let go while breathing out. Repeat until they are at ease.
Let your head flop foward and then slowly, smoothly and gently roll it up and around to the right and then back. Repeat for the left side.
Tighten every muscle in your face as much as you can and then release.
Yawn widely, letting all the tension it might be holding go. Repeat. Massage any points of residual tension.
Smile and stretch as wide as you can. Hold and release.
Extend it as far as you can (poke it out) and now sweep it around the outside of your mouth - a complete rotation to the left and then another to the right.
Repeat with your mouth closed, running your tongue around the outside of your teeth. Once to the left and then another to the right.
Flick your tongue rapidly in and out of your mouth as fast as you can.

Becoming conscious of how you are breathing is essential for sustaining and supporting your voice. This exercise will relax and center you while giving your voice grounded strength. Banish thinking and focus solely on the in and out flow of breath.

To warm your voice unite the breathing exercise above with sound.
Use the out breath to sound each of the vowels in turn. Let each go without force, flowing smoothly from your relaxed throat.
'A' is going to become ahhhhhhh... as in 'are'
'E' is Eeeeeeeeeeeee... as in 'easy'
'I' is Iiiiiiii... as in 'eye'
'O' is Ooooooo...as in 'Oh'
'U' is Uuuuuuuu...as in 'you'
Feel the shape of the sound in your mouth and enjoy its resonance.
Now try the consonants. Go through the alphabet or select those you need to to focus on.
Be sure to shape the letter fully and feel the sound each makes.
b, b, b, b, b...
c, c, c, c, c...
d, d, d, d, d...
f, f, f, f, f...
Hum on one note on one out breath feeling the resonance vibrate. Extend the hum to sliding up and down a scale without strain.
For articulation do a few rounds of tongue twisters.
Here's a couple to get you started.
Theophilus Thistler, the thistle sifter, in sifting a sieve of unsifted thistles,
thrust three thousand thistles through the thick of his thumb.
You know New York,
