Learning Experts Say: Narration is More Effective Than On-Screen Text


Because of time and cost constraints of voice recording, some companies opt to eliminate narration and settle for screen text only.  :-(

There are many reasons why audio narration is better for learning than on-screen text:

  • The narrator's voice captures the learner's attention, sets a pace and motivates learning.
  • With only on-screen text, it is difficult to read the text and view the graphics at the same time.
  • The narration delivers much more content. A two minute slide can have 300 spoken words but not more than 50 words of readable text.
  • The narrator uses phrasing and articulation in their speech to bring out the exact meaning of the material in a way that text cannot do.


Good news:  Speech-Over's text-to-speech voices eliminate the constraints of time and cost of voice recording allowing companies to add narration quickly and inexpensively.  :-)
