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. Popular motivational speakers include Tony Robbins, Les Brown and Naseer Khan.  The talk itself is often known as a pep talk.
