Hi
I gave a thank you speech on behalf of my husband. Personally, I feel a speech should not be long n boring like an oscar speech. For my speech, I thanked all the helpers( without listing their names) in English and both sets of parents in Chinese. You may get sample speech online, try key words like" wedding speech". That's where I get ideas on the structure of a speech. Dun get stress out, k. Do practice in front of mirror n pl dun bring a copy of your speech to the stage. It will appear v robotic n insincere lor.
