In the following video, Motley Fool senior technology analyst Eric Bleeker takes a look at the earnings report for Nuance Communications (NASDAQ:NUAN), which provides speech recognition applications, among other things, and is thought to be behind the voice recognition abilities of the iPhone's Siri. He notes how the company fell hard after releasing earnings, largely because it has committed a remarkably familiar earnings "crime" -- namely, contracting margins in the mobile space -- as net earnings trail behind revenue growth, spooking investors. Eric tells us why this is such a cause of investor concern, and what the silver lining might be.
