Most people giving a speech are so eager to get it finished that they speak much too quickly. Opening your mouth properly wil help to slow your speech down. You need to give the audience time to take in what you've just said.
Variety
You need to use plenty of variety in your voice. Vary the pitch, the pace and the power of your voice.
Mistakes
If you do make a mistake don't say sorry. The chances are that no one noticed and if you say sorry you'll only draw attention to the fact that you went wrong.
