A motivational speaker or inspirational speaker is a speaker who makes speeches intended to motivate or inspire an audience. Business entities may employ motivational speakers (for example) to communicate company strategy with clarity, to help employees to see the future in a positive light, and to inspire workers to pull together. The talk itself is often known as a pep talk. Motivational speakers are also commonly known as inspirational speakers and/or keynote speakers. Common motivational speaker topics include business, mentoring, team building, sales, inspiration, management and customer service.
