A battery of tests shows that Apple has improved its voice-driven personal assistant, Siri, with the iOS 7 update for iPhone and iPad, but its chief competitor Google Now, has caught up.
Both services got a grade of C+ by testers at Piper Jaffray, which is a slight improvement for Siri after Apple's service earned a grade of "C" last year in iOS 6.
After Piper Jaffray tried 800 queries, the firm's top Apple analyst Gene Munster found that iOS 7 has improved Siri's ability to translate speech better in a noisy environment, with accuracy increasing from 83% to 94%.
Google Now's grade improved from "D-" to "C+," with major improvements in comprehension and accuracy. Google Now's ability to understand users in a noisy environment grew from 78% accuracy in December 2012 to 92% in the latest tests performed this month.
