Siri's Accuracy Continues to Improve as Apple Works to Reduce Reliance on Google

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.

The improvements in Siri's understanding come alongside but separate from Apple's continued efforts to reduce its reliance on Google, as evidenced by Siri's shift to emphasize Bing, Wikipedia, and WolframAlpha results. In Munster's most recent testing, only 4 percent of Siri's answers relied on Google, compared to 17 percent in August testing and 27 percent in December 2012.

Munster also compares Siri to Google Now, finding that the two services are now essentially tied in effectiveness with a "C+" score after Siri held a substantial lead in the year-ago testing. In the latest testing, Google Now held small leads in content areas such as commerce and information, while Siri performed significantly better for operating system controls.

There is no way these charts are accurate. Even when I speak as clearly as possible and enunciate every syllable, Siri understands me about 40% of the time.


I get 90% accuracy, I don't know what's going on with you.

So even though its accuracy at understanding has gone up, the accuracy of its answers has actually got worse?

The one thing I will greatly defend Apple and Siri for is trying to understand people's voices. People either have a strong accent, speak with a lisp, speak too fast, speak too slow, speak with a low register voice, have an annoying voice, mumble their words, garble their words and most of all they try and use Siri in a noisy atmosphere along with any of the above.

No matter what, it's still an electronic device and people just have to learn to speak properly based on the source or just don't use as you've appeared to do. You say you have no need for voice control, it's not just about voice control. Many times I need to look up sports scores, it's much faster and easier just to ask Siri the game stats than typing them in or opening an app and searching.


Never defend a technology! Technology is meant to develop to serve the requirements/limitations of existing human behaviour; human behaviour shouldn't be expected to adapt to meet the requirements/limitations of technology.

I have had the opposite experience. After seeing steady improvement in Siri, it has recently gotten worse and become almost unusable for me.

Specifically, I use Siri a lot to play music in the car. I will say "Play Song X" or "Play Album Y". Siri used to be pretty good at hearing the name of the song and finding it in my music library. Now it frequently hear the names incorrectly. Even when it does hear the correct name, it will play a song with a completely different name or simply say "Sorry, I couldn't find that in your music". What do you mean you couldn't find David Bowie in my music??? It's right there!

This regression is quite infuriating. Also, Siri still often fails to respond ("Sorry, there's something wrong") or take 20+ seconds to respond with the wrong answer. I believe we need to give all of Apple's web services time to gather data and make iterative improvements, but I have very little tolerance when they actually get worse over time.

I don't know, that net percentage increase (4% better) year over year seems kind of low to me. Am I the only one who feels that way? Not my field of study, so I'm not entirely sure if this is supposed to be impressive.

Barry Kripke, is that you? :D

I agree. I get close to 90% and I'm from overseas :D

Siri, the least used 'feature' on my iPhone. Maybe someday I'll take the time to really understand how to make it work for me, but in the meantime, I'd rather type something into Google, or Yelp, or Maps, or....

Until Apple adds on-device voice parsing (like Google does) and rely less on server based transcription, Siri will never be as good and fast as Google Now.


Offline parsing is rarely done on Android. It is there as a backup. What makes Google fast is it is able to translate it in real time and not have to wait for you to finish. You can see this happening live as it tends to guess what you say but when you are done it will go back and correct some words based on the totality of what you said.
