An extempore speech, also known as an impromptu speech, is a type of speech that is delivered without prior preparation or rehearsal. In an extempore speech, the speaker is given a topic or a prompt on the spot and is expected to speak spontaneously and convincingly about it.

The word extempore is derived from the Latin word ex tempore,which means "on the spur of the moment." The purpose of an extempore speech is to test a speaker's ability to think quickly, organize thoughts, and deliver a coherent and persuasive speech without relying on extensive preparation or notes.
