Not surprising: According to https://en.wikipedia.org/wiki/Reading_(process)#Assessment reading for comprehension normally falls in the 200-400wpm range. 10 seconds to read 49 words is 294wpm, which is smack in the middle of that range.

For comparison, https://en.wikipedia.org/wiki/Words_per_minute#Speech_and_li... claims that 250wpm is the speed auctioneers speak at and that normal speech is 150-160wpm.

Getting words spoken at you is terribly inefficient compared to reading them.
