So you have probably seen us post various tidbits on audio such as Emulating Human Voice-overs with TTS Voices on the blog.

Visual Purple simulations do allow for text (otherwise known as closed captioning) to appear in all of the simulation (not just at the decision points). Thus supporting those that learn better by reading as opposed to listening. Fully narrated scenes definitely enhance the learners’ cognitive processing, thus audio can be very effective for a variety of learning styles.
