To give a speech we must take into account who or whom will be our listeners, the manner we express our ideas or message (Body gestures - Pronunciation - Fluency - Material support and so forth...) with the only one purpose to convince, to persuade, to inform and to entertain your audience.
There are four types of speeches according your topic and audience:
Impromptu speech.
Memorized speech
Manuscript speech
Outline or extemporaneous speech
Below this post there is a link with a video that will help you to make an efficient manuscript speech.
I hope you like it.. =)
