What is a short speech that introduces someone to an audience called?

The term for a short speech that introduces someone to an audience is indeed an introduction speech. This type of speech is typically delivered before another speaker takes the stage, providing background information about the speaker's credentials, achievements, and relevance to the topic at hand. The purpose of an introduction speech is to create a positive atmosphere and to prepare the audience for what they are about to hear from the main speaker.

In contrast, a keynote speech is a more extensive address that sets the central theme for an event or conference. A farewell speech is delivered when someone is leaving or ending their associations, often reflecting on experiences and goodbyes. An acceptance speech is made when someone is receiving an award or recognition, focusing on gratitude and acknowledgment of those who contributed to their success. Each of these serves different purposes in the context of public speaking, but none encapsulates the function of introducing an individual to an audience like an introduction speech does.
