The different steps of the assignment

1) Learning about how to construct a speech: examples and tips
2) Doing background research, finding the topic you want to focus on, writing down facts, statistics etc. and creating a mind map of the main points you are going to deal with
3) Writing the actual speech

4) The written speech will be assessed and marked by the teacher as a written assignment

5) Once you get the marked speech back (with any possible corrections) you then rehearse reading it out loud (= "speaking it") in front of the class - here the focus should be on your tone of voice, intonation, speed of speech, body language etc. but you don't have to learn the speech by heart.
