While Google comprehends 100% of searches, Siri was only able to comprehend 83% of the prompted questions on a busy Minneapolis street. In terms of answer accuracy, Siri correctly answered 62% of queries on the street compared to Google's estimated 86% answer accuracy. Based on these results, we give Google an A+ for comprehension and a B+ for accuracy while we give Siri a B for comprehension and a D for accuracy. Click to expand...

In what should not be a surprise given Siri's beta status and its use of new technology for voice interaction with mobile devices, a study from Piper Jaffray analyst Gene Munster finds that Siri's abilities are still eclipsed by the traditional text-entry Google searches that have been in place for years.The study included presenting Siri with 800 queries in each of two environments, a quiet room and a busy urban street, and then assessing Siri's ability to correctly interpret the queries and provide correct responses. Specifically addressing the outdoor testing, Munster notes:But while Siri has some room for improvement, Munster acknowledges that the technology is only in its infancy and he remains "optimistic about its future" with an eye toward iOS 6 as bringing substantial improvements.Piper Jaffray's testing was conducted using the iPhone's built-in microphone in the quiet setting and Skullcandy microphone headphones for the outdoor setting, with Siri's ability to correctly comprehend queries falling from 89% to 83% when moving outdoors to the noisy urban setting. On the accuracy side, Google's 86% rating is derived from comScore data showing that Google generates 1.14 search result pages per search, suggesting that roughly 86% of time Google presents the data the user is looking for within the first few results.Piper Jaffray also analyzed the sources for Siri's results, finding that Google provided 60% of the answers, with Yelp and other sources filling in the remainder.Munster estimates that Google's share of Siri results will drop to 48% with the launch of iOS 6 as navigation, sports, and movie queries shift over to Apple and its new partners.Article Link: Siri Shows Increasing Promise, But Accuracy Falls Short of Google Text Searches
