What Is a Voice-over? 

According to Wikipedia, a voice-over is a production technique and a usually pre-recorded sound of a voice that is added to a film or video, commonly used in documentaries or news reports to explain information. 

But nowadays, with eLearning being so popular, voice-overs have become a crucial tool for instructors. It is important for them to know how to add audio narrations to online courses and presentations and record voice-overs for instructional videos.

Why Should You Use Voice-Overs in eLearning?

There are at least four reasons making a voice-over for your next course is definitely worth a try:

Enhanced comprehension

If you use images accompanied by a voice-over, the auditory and visual channels can reinforce each other and communicate the message more effectively. Texts and imagery alone may not be sufficient for an effective learning experience. By combining them with audio, you can bring more context, provide needed explanations, and add a human touch to your course or instructional video.

Let’s perform a brief experiment. At iSpring, we record voice-overs for every type of video tutorial. Take a look at this video, for example, and try to turn the sound off. It really makes a video hard to follow, doesn’t it?

Assistance for auditory learners

Another point is how to address various learning styles well. It’s hard to overestimate the importance of voice-overs for auditory learners. For this category in particular, your voice and intonation can really help the viewer comprehend new information.

“Voice-overs can be a great add, especially for auditory learners.”

 Hellen M., Technical Trainer

Below is a good example of an explainer video that appeals to different sensory styles. However, if you imagine it without this beautiful voice-over, subtitles alone won’t be enough to get the message right, and the video might lose its charm.

Accessible learning content 

Voice-overs are critical if you want to make your eLearning content truly accessible for people with visual impairments. Plus, it’s becoming increasingly common to use eLearning when providing support to people with intellectual and developmental disabilities. Here, a familiar voice that uses the right intonation and speaks at an accessible pace comforts learners and guides them through the new learning practice seamlessly.    

Less effort from instructors

Voice-overs can also be extremely helpful from the instructor’s perspective. Consider it as an option if you are used to delivering lectures to your learners but now need to turn your lecture material into an online course quickly. Instead of writing the text all over again, you can narrate the material like you always have and supplement your course with more visuals.

Tips on How to Prepare for a Voice-over Recording

Now that you have technical instructions on how to record your voice for eLearning courses and videos, here are a few tips that will help you improve the quality of the recording.

Find a quiet place to work

The last thing you want is to have echoes and mumbling voices on your recording. So, finding a small, quiet place to record is a must. There should be no open windows, ticking clock, or beeping devices. Also, sound absorbing materials and objects (special panels, velvet curtains, blanketed walls, and soft furniture) are highly advisable. One more note: ensure that nobody enters the room while you’re recording – that’s the reason behind using the ON AIR sign on radio and television studio doors.

Get your mind and body ready 

Before recording, you need to make sure that your voice is in a good shape. A few days before the recording session, protect yourself from getting cold, refrain from smoking/drinking, and don’t yell. During the day of the recording, try not to talk too much, stay hydrated, and be mindful of what you eat and drink: chocolate, carbonated beverages, and dairy products can dry out the vocal cords and cause hoarseness. Finally, do some warm-up exercises and tongue twisters to reduce strain on the vocal cords.

Have a back-up while recording

It will be better if you wear headphones while recording, so you can pay attention to the sound of your voice and monitor your pronunciation. Have a glass of water at hand and, if it’s going to be a long run, hydrate your lips with lip balm during pauses between sessions. Quick breaks before sessions are very important: they allow you to take a moment to relax and restore breathing. 

Make it easier to comprehend 

And last but not least, speak clearly and concisely. There is a huge difference between written and spoken language, so try to avoid long complex structures and vague formulations. It’s best to stick to the point and tell about one idea at a time, so learners can comprehend the information better. 

Frequently Asked Questions

Here are the answers to a few frequently asked questions about making voice-overs.

Do I need a professional recording setup to do voice-overs? 

It’s a fact that most trainers and instructors make their voice-overs at home or right in the workplace. So, the answer is no; you don’t need expensive professional recording equipment. An authoring tool with proper video and audio capabilities will be sufficient. But it’s best to choose the right room where you will set up your ‘studio’ and prepare it for the recording session.

Will my laptop microphone be OK for recording voice-overs?

Yes, it will, provided that you prepare for the pre-production and don’t expect an extraordinary outcome. To ensure decent recording quality, avoid echoing, ambient noises, and large spaces. But for enhanced sound quality, you’ll definitely need a more sophisticated mic. Check out this guide on microphones.
