This weekโs E-Learning Heroes Challenge is Applying Multimedia Learning Priniciples to E-Learning Design.ย ย
If you’re not already familiar with the work of Richard E. Mayer and his Principles for Multimedia Learning, a great place to start is David Anderson’s introduction to this challenge and this summary from FutureLearn.
Even if you have never heard of Mayer or his work, you will probably have heard of his Redundancy Principle, whichย tells us ‘not to add printed text to spoken text’.ย
This articleย details how to present your multimedia content in the most effectiveย and efficient way, by:
- Explaining a visual through audio or text, NOT both
- NOT adding on-screen text to narrated graphics
- Adding on-screen text ONLY where there is no video or image competing for the learner’s attention
Nonetheless, you should still add closed captions and transcripts to ensure your course is ‘508 compliant’.
The Redundancy Principle does not apply here, as captions can be switched on and off and transcripts can be read separately to your media content. You’re not forcing the learner to read this text – it’s only there if they need it.
But it’s not quite as easy to provide learners with a range of voices and accents, which can also have a significant impact on how your content is received.
The Voice Principle states that ‘people learn better when the words are spoken in a standard-accented human voice rather than a machine voice or foreign-accented human voice.’
The Voice Priniciple
For this week’s demo, I created a practical demonstration of theย Voice Principleย by pairing Storyline’s Text-To-Speech function with animated characters created in Vyond.
To prove the point that learners respond better to a ‘standard accented human voice’, I used this method to add a live polling function.

Why are you doing this Dave?
But what if you don’t have the budget to hire a professional?ย You can create high quality narration on a shoestring, as the talented Josh Ritterย outlines in his DIY Narrator podcast: Voice your feelings
What do you think about the Voice Principle?ย Sound off in the comments!
“In certain settings Text-to-Speech can be suitable for your final product” – just like my demo for this week’s E-Learning Heroes Challenge, Design in a 100×100 Story Size.

Absolutely LOVE this!! Fits with my (albeit slightly biased) opinion that humans much prefer to be trained by humans and not machines, and that using AI voices sends a moral signal to the learner that the company doesn’t care enough to use human voices.
