Piper Jaffray analyst Gene Munster, who has regularly assessed Siri's accuracy in terms of correctly interpreting and answering queries, has issued the latest version of his Siri report card, noting that Siri has continued to improve under iOS 7, particularly in terms of being able to properly interpret questions being asked.The primary improvement between Siri in iOS 6 and iOS 7 came from its performance in noisier areas, where Siri was able to translate better through a noisy environment (94% vs. 83% correct in Aug iOS 6). Based on our testing, iOS 7 Siri's net ability to answer questions (factors in questions not correctly understood) improved to 79% from 77% in August with iOS 6.
