3x speed is an accessibility feature for anyone who has trouble paying attention at slower rates. The rules of grammar mean that people often need to speak far more words than is necessary for some concepts. Pause and rewind buttons exist for passages which are actually information dense. (The same is true of writing; entire paragraphs exist for no reason other than maintaining structure. Fortunately, well-edited works follow rules of paragraph style and structure -- first words, subect; final words, conclusion -- which enable effective skimming.)
