What type of speaking style allows for a natural flow of conversation?

The correct choice is extemporaneous speaking because this style involves the speaker preparing and practicing their ideas but not memorizing them verbatim. Instead, the speaker uses key points or an outline, which allows for a conversational and engaging delivery. This approach enables the speaker to maintain eye contact with the audience, respond to their reactions, and adapt the message as necessary in real time, resulting in a more natural flow of conversation.

Memorized speaking, in contrast, requires the speaker to memorize the entire speech, which can lead to a more rigid presentation style lacking the spontaneity and engagement that comes with a conversational approach. Reading directly from notes can hinder the speaker’s ability to connect with the audience, as it typically results in less eye contact and a more static delivery. Impromptu speaking involves delivering a speech without prior preparation, which can indeed feel conversational but may lack the structure and clarity that comes from an extemporaneous approach, often resulting in a more chaotic flow.
