I need to memorise and deliever a speech but...?

Maybe some of these tips will help you.

Tips for doing a presentation

Know your subject matter really well and practice reading to your dog or just out loud to yourself ahead of time.

Look over the heads of the class at a point on the wall in the back of the room. The class will think you are looking at them, and the teacher will think you are looking at your audience.

Don't notice any reaction from the class. Their reaction doesn't matter, but it might make you feel more nervous.

Concentrate on what you are saying rather than how you are saying it.

Don't try to keep from stuttering as that will make you stutter more. If you stutter, just let it happen.

Maintain a steady pace, not too fast, and don't get in a hurry to "get it over with."

Speak in a relaxed manner and pause every so often.

Start into words easily keeping your lips, tongue, and jaw relaxed.

Realize that stuttering occurs more often when you are trying NOT to stutter, when you are under stress, and when you are tired.

First, read the speech out loud start to finish again and again.

After doing that 4 or 5 times, try letting your eyes leave the page when you find you're at a spot you're already familiar with.

If you're planning on taking notes up with you, highlight crucial sentences for each topic, so at a glance you can look down if you've lost your place and quickly scan over your highlighted points to get you back on track.

If you begin to stutter, just stop and take a breath, maybe a sip of water. An audience responds better to a pause than someone trying to work through a word. Many people have issues speaking publically, and no one will notice if you pause for a second. Avoid saying "Uh" and "Um", and instead just leave a silence if you're searching for a word.

If you can, practise speaking in front of a mirror. When speaking to a crowd, try to let your eyes rest in the middle of the crowd, so you're not looking above or below them. Keep your face neutral, and smile for emphasis on certain points.

I spent years on an improv team and had terrible stage fright, and when we got really popular and started going across the country I had to learn to speak better. I've used this technique to memorize monolouges for plays.

Make short flash cards.
