Explanation:

In everyday language, a speech is a message. It is the verbal and oral act of addressing an audience in order to communicate or expose something, but also to persuade.

For linguistics and the social sciences, discourse is a form of written (text) or spoken language (conversation in its social, political or cultural context). Anthropology and ethnography also speak of a communication event. Philosophy, in turn, considers discourse to be a social system of thought or ideas. However, regardless of the area addressed, all discourse has a goal, and the main elements for identifying that goal are: Cultural context, central ideas, language and audience

The cultural context reveals which culture that discourse is linked to and what customs the discourse wishes to achieve through it. From the central ideas it is possible to understand the specific subject that the discourse wishes to address and why a discourse about that subject is necessary. Language and audience are two elements that show which population that discourse wishes to reach and which geographical boundaries will be reached from it.
