Which of the following modes of speech delivery occurs when a speaker uses an outline or brief notes?

Extemporaneous delivery is characterized by the use of an outline or brief notes rather than a fully written speech or memorization of the entire content. This mode allows the speaker to engage with the audience more naturally, as it promotes spontaneity and adaptability while still relying on a structured framework. The speaker can adjust their delivery and emphasis based on audience reactions and maintain eye contact, which facilitates better connection and engagement with listeners.

In contrast, impromptu speaking typically involves delivering a speech on the spot without any preparation or notes, while manuscript delivery requires reading from a prepared script word-for-word. Memorized speech delivery means the speaker has committed the entire content to memory, which can limit spontaneity and interaction. Therefore, extemporaneous speaking stands out as the method that balances preparation with flexibility, making it an effective choice for engaging communication.
