In theory, having a little personal assistant living in your phone is pretty awesome. But if she can’t understand you half the time, what good is she? When put to the test by Piper Jaffray’s Internet research analyst Gene Munster, the iPhone’s Siri could only understand 83 percent of the 800 questions she was asked on a busy Minneapolis street, and responded accurately only 62 percent of the time. (Her results in a quiet room weren’t much better—89 percent comprehension, 68 percent accuracy.) This hardly stacks up to Google Search, which Munster says Siri is about two years behind. But he’s confident that Apple’s iOS 6 being released this fall will be a big improvement. Until then, it seems metropolitan Minnesotans should just Google it.
