You can likely expect elearning users to be more focused, and therefore a bit less patient, especially with narration that reads long blocks of on-screen text. It is therefore often desirable to create voiceover narration with a slightly quicker pacing than other traditional media, and keeping it as lean as possible.
Also keep in mind that these segments will be often played back through lower quality computer speakers, or laptop speakers with less than optimal intelligibility. And many users may speak other languages as their primary language. This suggests that along with the quicker pacing, the narrator should strive to place additional emphasis on clearly pronouncing the narrative, using slightly higher registers when possible, and/or boosting EQ to increase the clarity of the enunciation.
