Speed listening is a sub-classification of speed learning where students try to increase the pace at which they can listen while maintaining complete understanding. It allows students to absorb more details while listening in a shorter span of time. It is most widely used when using text-to-speech applications such as Speechify, audiobook services such as Audible, or Apple iTunes Podcast apps, etc. Entrepreneur Cliff Weitzman and speed learner Max Deutsch have made their marks to be credited with redeeming this learning type.
