I found this at Visual.ly. They’re awesome, BTW. You can actually make your own amazing infographics like this there. Just remember this: some languages, according to this research, do move just a little faster, but generally, it’s not that folks are talking fast — you’re understanding slow.
From the site:
Ever wondered why some languages sound like they’re spoken much faster than others? Yet, in dubbed movies the words seemingly fit the actors’ mouth movement. That’s what researchers at Universite de Lyon wanted to explain when they set out to research one phenomenon: the speed of language. This infographics shows how they did it, and what they found.
