I think if you are doing a best man speech or any other speech of that nature then I am not sure whether using programs like PowerPoint would be the right thing. However, if you are doing a speech for work or at a society or perhaps as school or university, then definitely it is a good idea.

Programs like PowerPoint are great tools to help you remember where you are with your speech or presentation and are a visual aid to make it that little bit more interesting.

If you are thinking about using it for a best mans speech then I would include some pictures and especially ones of the groom and ones that are particularly compromising and where he is a child – these always get a laugh and help to take the focus away from you.
