If you make videos — especially how-to and explainer videos — you will need to record voice overs. In fact, depending on how many videos you create, you may have to do a lot of voice over work.
Some might think that the audio portion of a video takes a backseat to the visual portions, but that’s not true.
Most video watchers note that they are more likely to stop watching a video with bad audio vs. lower-quality video. In fact, a recent TechSmith study of video viewing habits showed that more than 25% of video viewers watched a video all the way through because the audio was good — more than those who said professional video style was most important.
