Impromptu:
* No preparation: This type of speaking happens with absolutely no forewarning. You are given a topic on the spot and expected to speak about it immediately.
* Focus on the moment: Impromptu speaking is all about thinking on your feet and responding to the situation in real-time.
* Limited organization: Structure and organization are often sacrificed for speed and spontaneity.
* Common examples: Responding to a surprise question in a meeting, giving a toast at a wedding, being interviewed by a reporter.
Extemporaneous:
* Limited preparation: You are given a topic in advance, but you don't have time to write a full script or memorize it.
* Focus on outlining and key points: You use the time you have to create an outline and identify the main points you want to cover.
* More structured: Extemporaneous speeches have more structure and organization than impromptu speeches.
* Common examples: Giving a presentation in class, delivering a keynote address, participating in a debate.
Here's a helpful analogy:
* Impromptu is like playing a game of improv: You have no script, and you have to come up with your lines as you go.
* Extemporaneous is like giving a speech with notes: You have a general idea of what you want to say, but you're not reading a script.
In short:
* Impromptu = no preparation, pure spontaneity
* Extemporaneous = limited preparation, structured spontaneity
Both impromptu and extemporaneous speaking are valuable skills that can help you in various situations.
