Answer:
A statement phrased as ""to inform the audience about (my topic)"" is known as: a specific purpose statement.
Step-by-step explanation:
When writing a speech, one of the very first steps is to establish its purpose. The general purpose of a speech can be to inform, to motivate, to entertain, or to persuade.

The specific purpose statement will, of course, vary according to the general purpose of the speech. The statement that uses the verb "to inform" refers to an informative speech.
