What accurately defines extemporaneous speaking?

Extemporaneous speaking is characterized by a balanced approach that combines careful research, organization, and rehearsing. This style allows the speaker to prepare extensively on the topic, understanding the material in-depth, which contributes to a more confident and engaging delivery. The speaker typically prepares an outline and key points, and while they do not memorize the speech verbatim, they rely on their knowledge and preparation to deliver the content conversationally and interactively.

This method contrasts sharply with other forms of speaking, such as impromptu speaking, which is spontaneous and lacks preparation, and manuscript speaking, where the speaker reads the speech word for word. It also differs from memorized speech delivery, which relies entirely on memory and does not incorporate notes. The extemporaneous style is particularly effective in public speaking contexts as it allows for adaptability and responsiveness to the audience while maintaining coherence and structure in the message conveyed.
