Manyprojects use professional voice artists to record the voice-over for self-paced programs, rather than having the subject matter experts or the authors to do so. This is in fact an efficient way to develop the program, and it is a common practice for corporate training.
However, in the academic world, I would keep the academics’ voice. This will improve the course’s image and increase the audience’s confidence in the program.
Quite often, a good researcher is not necessarily a good speaker. We can work together to improve the scripts so that the audience only get the important and the right message that they should, but we can’t improve an academic’s speaking skills in a short time. That’s why it is quite necessary for e-learning developers to edit the voice-over to make it more attractive. And I don’t like those programs on the market that leave the recording as it is. That doesn’t show the essence of e-learning – I mean the benefits of e-learning over face-to-face lectures and their video or audio recording.
Here’s an example I can give you. Compare the two video clips below:
So, now you must be able to tell which version you would prefer. Just with a little bit more of editing, you can improve the learning experience a lot!
