cultural context, central ideas, language, audience.

Explanation:

The speaker should determine the central ideas which he/she wants to address in the speech. These ideas should be expressed in a simple and concise manner.

Cultural context and the audience are closely related elements - the speaker should definitely take into consideration which people are going to listen to his/her speech, and what are the characteristics of their culture. Taking these elements into account will help the speaker connect with the audience.

Finally, language itself is a means used to connect with the people in the audience. The use of persuasive techniques and rhetoric devices plays a crucial role in any speech. Depending on the purpose of the speech, as well as the target group (people's age, occupation, etc), type of language used also varies.
