It usually best not to attempt an extemporaneous speech unless you are very experienced and knowledgeable about your topic.

Explanation:

An extemporaneous speech is one that addresses a subject that is not proper or characteristic of the time or the moment in which the speech occurs. For this reason, the speaker must understand the subject very well in order not to pass wrong information, nor to get lost in the context.

Preparation is the key to speaking effectively in an extemporaneous speech, whether in a house-to-house presentation or in a speech in the gallery. If you have to give a speech out of time, prepare a good outline and study the subject very much.
