In which speaking style is the content typically memorized or read verbatim?

The identified speaking style where the content is typically memorized or read verbatim is formal speech. In formal speech, the presenter prepares meticulously to ensure accuracy and coherence, which often involves memorizing the material or reading it from a script. This approach is common in settings such as official addresses, lectures, or formal presentations, where precision in language and adherence to a structured format are paramount.

In contrast, extemporaneous speech involves speaking from a prepared outline but allows for spontaneity and a more conversational tone. Impromptu speech is characterized by its spontaneity, where the speaker has little to no preparation and must organize their thoughts on the spot. Conversational speech is more informal and natural, relying on a relaxed and engaging dialogue rather than memorized content.
