Adding voiceover audio to eLearning enhances the learner experience. And before you spend thousands of dollars hiring voiceover talent to record your audio, you should know: your voice is fine (nobody likes their own voice so trust me on this, yours will do nicely). I've been creating eLearning for years (and years and years). I've found that the voiceover audio does not have to be highly produced to be effective. In fact, home-grown audio works fine provided the audio doesn't contain loud, annoying, distracting background noise, or the narrator has a very thick accent that hinders learner comprehension.
