What is speech according to manner of delivery?

Speech according to manner of delivery refers to the way in which spoken communication is presented to an audience. It can be categorized into various styles, such as impromptu (delivered spontaneously), extemporaneous (prepared but delivered without a script), manuscript (read verbatim from a text), and memorized (recited from memory). Each style affects the speaker's connection with the audience and the overall effectiveness of the message. The choice of delivery method often depends on the context, purpose, and audience of the speech.
