Embedding audio in eLearning courses enhances learner engagement as well as the efficiency of the learning material. Use of audio provides significant benefits in learning, as it adds interest and engagement to the learner and conveys the emotions of the characters used. However ,indiscriminate use of audio might make its existence either redundant or prominent. Thus, you need to use audio cautiously and cleverly in order to make the eLearning courses exciting and engaging.
Here are a few tips on how to make effective use of audio in eLearning courses.
Audio should be in a conversational tone
Engaging audio enhances the interest levels of the learners. So, make the script conversational. A good narration sounds as if a person is talking to another. Use words such as oh, wow, really, that’s great, oh no and so on. These “emotional words” help your learners connect with situations presented in the course better.
Audio should meet the quality standards
Rather than using audio of poor quality, it is better not to use audio at all. Avoid unwanted noise and mismatch between audio and onscreen text. You also need to make sure that the audio loads fast to avoid learner frustration.Thus, audio should be recorded in a professional recording studio , where in the recording engineers will be able to sort out the technical issues if any and ensures that audio narration is done as per the quality standards.
Use professional voice
Audio narration is an art. Use of a professional voice adds depth and richness to your course. So, it is always recommended to hire professionals for narrating the audio script of the eLearning course.
Try to use more than one audio character
It is a best practice to use more than one audio character in the course.For example, in a scenario based approach, you can add a variety of audio characters that make the eLearning course engaging and effective.
Keep it short and simple
Lengthy and tedious audio makes the learners feel annoyed and boring, and they eventually lose their interest. The more you elaborate the audio narration, moreare the chances for the learners to get confused. According to the cognitive load theory, audio should not cover everything that is on-screen, as this may distract the learner. One of the features of good audio narration is that it is simple and short.
Avoid ‘Shhh’ and ‘umm’ sounds in audio
Using properly planned background sounds makes the course inviting and exciting. A good soundtrack can create emotional cues. Whereas unexpected footsteps like banging doors ruin a recording. So, be careful and try to avoid unnecessary humming sounds in between the audio narration.
