Speech For Wedding

Do I have to give a speech at the wedding?
Well, my sisters wedding is in 2 days. I am the maid of honor, but not sure if I want to give a speech. I said I do not have to, not because I am a VERY shy person and I hate speaking in front of many people. I'm not even sure what he would say if I was giving a speech. You think I should give?
No. I hate the stress out of it and not be able to enjoy the day.
