Final answer:
Extemporaneous delivery allows for greater spontaneity and audience engagement by providing the flexibility to adjust speeches in real-time. The approach facilitates a conversational tone and natural use of gestures, but still requires thorough preparation and practice for effective delivery.
Step-by-step explanation:
One of the advantages of extemporaneous delivery mentioned in your textbook is that it allows greater spontaneity compared to speaking from a manuscript. Extemporaneous speaking involves speaking from notes or a memorized outline but without the entire speech being written out. This delivery method strikes a balance between fully scripted speeches and impromptu speaking, allowing the speaker to engage with the audience more directly and adjust their remarks in real-time without being tied to a full script.
Practicing extemporaneous speaking can enhance the speaker's effectiveness in several ways. It improves the ability to articulate words clearly and delivers them in a more conversational tone, which helps build a connection with the audience. Moreover, because the speaker is not reading from a manuscript, there is an opportunity to utilize gestures, expressions, and movement more naturally, which can help to reinforce the spoken message and maintain audience interest.
While extemporaneous delivery benefits from the spontaneity and engagement with the audience, the speaker still needs to prepare and practice thoroughly to ensure fluency and to minimize the use of verbal fillers. However, the final result is often a more dynamic and memorable presentation, which balances well-prepared content with the flexibility to adapt to the audience's reaction and maintain their attention.
