Not all eLearning programmes need to have audio, but it can help learners and create interest if used well. This blog highlights the different questions you should ask before using audio in your eLearning and the different ways to incorporate it. There are a number of practical questions you can ask yourself before you think about using audio. These will not only help you decide if you need audio but also how you might manage the recording and updating of it.
1. What technology do your target audience use?
Is it likely that your target audience:
You can, of course, add audio transcripts for those that don’t have speakers or headphones, but it would be unnecessary providing audio if the majority of your learners don’t have them.
Audio increases the file size of your eLearning and it can significantly slow down loading times.
2. What are your budget limitations and timescales?
Consider if you are willing to:
Invest in good quality audio.
This can be as simple as investing in a good quality microphone, and investing some more on soundproofing equipment. But don’t compromise on your audio.
According to Byron Reeves and Clifford Nass at Stanford University, audio quality matters a lot so online learners are unforgiving when it’s recorded badly. If you are in doubt about the quality of your audio, have it recorded professionally.
This can take some time, especially if your text builds onscreen. Be prepared to add your audio at the end once all of your text is finalised and agreed, otherwise your audio will be out of date very quickly.
An audio transcript will help users with hearing difficulties read the audio at their own pace. If you add audio, make sure you are prepared to add this and update it when you make any changes to your content.
3. Will your programme require any updates and if so, how often?
If you anticipate that you will make a lot of updates to your content over time, consider if you are willing to record new audio each time you make the changes.
This is why deciding on the approach to audio is especially important from the onset – if you choose to record all of your onscreen text, are you prepared to record all of this content if you make even minor updates to your content?
4. What is the nature of your content?
The subject(s) you will be covering will of course help you decide how much audio you will use in your programme.
