An impromptu speech is a type of speech where the speaker has to prepare the speech in a couple of minutes. The speaker gets only 2-3 minutes to prepare the speech that will last for 5-10 minutes. These types of speeches are short and simple. This genre of speech is a great way of testing the speakers public speaking, creative writing, and communication skills. Impromptu speech topics are becoming very popular for practicing public speaking skills. Generally the preparation time is very less, perhaps a few minutes for articulating a 5-minute long speech or even less.
