Why Use Audio Narration in eLearning?
Audio narration in e-learning courses is a powerful means of improving the efficacy of the material. Adding audio and video can result in better understanding of the learning material. It helps in making content persuasive. The main purpose of audio in e-learning courses is to keep the learner engaged for an extended period of time. In this article, we will discuss on why it is important to add audio in eLearning courses and how it affects learner's learning ability.
Audio narration can have a more meaningful impact on e-learning courses if it is used as a supplement to learning. The narrator should sound like an expert on the subject. However, even if one isn't an expert, one should have the proper inflection and intonation for relevant emphasis. Proper inflection includes a smooth, natural sense of dialogue, pace and tone and should sound like the narrator is speaking to you.
Narration, in order to be powerful, should be spoken in a manner that supports learning. Use audio judiciously only. Only where there is a need to explain a process or process flows, complicated definitions, key points, simulations, etc. This will also prevent the learner from getting into a passive mode.
Providing audio controls are a must as it allows the learner to turn the narration on or off as needed and gives him or her more control over his learning experience. Always, synchronizing the audio narration and animation properly helps to explain the text and graphics better.
When it comes to the use of humor in narration, ensure that the recording captures it correctly. For instance, a very serious voice might dilute your attempt at humor.
Thus audio in e-learning courses does affect learning as it complements display of text by talking about it. The 'Telling' part supports and explains visuals clearly. For example, if we know that good visual presentations include limited text and incorporate interactive components then audio will be a key part of the learning process.
But, how much narration in e-learning is needed?
Audio has to be the part of the complete picture, we learn best if we see, hear or do. However, the entire course shouldn't be narrated. Do not read each word of on screen text. Make sure your audio provides more than the on screen text, which ideally should be very brief and concise. Use audio only when it is instructionally needed.
Here are a few advantages of effective use of audio narration in e-learning.
Adding audio in the courses, makes the information more likely to be retained. It can provide detailed explanations about slide objects, without cluttering the screen with text and adds an element of interest and engagement to the course material. Audio narration also provides an element of authenticity to the course material.
However, on the flip side, having audio narration in e-learning can affect loading as huge audio file make loading slow. Also, overuse of audio or poor quality of recording can distract learners and be counterproductive. And, audio not thematically connected to the on-screen text and graphics will confuse learners as they won't be able to concentrate on the on-screen text and the voiceover simultaneously.
Thus, narration and voiceovers can have a meaningful impact on e-learning if they are used as a supplement to learning, whether in role playing, providing feedback to activities or in simulations. Audio should always be aligned to support learning principles if it is to improve learning significantly.
