Which mode of speech delivery is NOT recommended for most public speaking situations because it prevents audience adaptation?

The mode of speech delivery that is not recommended for most public speaking situations because it prevents audience adaptation is the manuscript. When a speaker relies on a manuscript, they read their speech word-for-word from a written document. This method can create a disconnect between the speaker and the audience, as it limits the speaker's ability to engage with the audience's reactions and adapt their delivery in real-time.

Using a manuscript can hinder the speaker’s ability to make eye contact, respond to audience cues, or adjust the message based on audience feedback. Engagement with the audience is crucial in effective public speaking. By reading from a manuscript, the speaker may miss opportunities to emphasize important points, clarify misunderstandings, or adjust to the emotional tone of the room, which is essential for maintaining audience interest and involvement.

In contrast, other modes such as impromptu, memorized, or extemporaneous allow for more interaction and adaptability, helping speakers connect with their audience and create a more dynamic presentation.
