Speed. 150 wpm talking vs 200-250 wpm with stenography. Putting on my narrator’s hat for a moment, I’d also point out that speaking clearly for hours on end is hard, and not something you can do without preparation (copious amounts of water, a room with little background noise, a good microphone, etc). Any of the preparation that’s skipped makes it harder to speak clearly and be understood.
