Phillip Elmer-DeWitt of Fortune reports:
- Google understands 100% of the questions (not surprisingly, since they are keyed in)
- Google replies accurately 86% of the time
- Siri comprehends 83% of queries in noisy conditions, 89% in a quiet room
- Siri answers accurately 62% of the time on the street and 68% in a quiet room.
Elmer-DeWitt further notes that Gene Munster of Piper Jaffray ”estimates that Siri is more than two years behind Google in its learning curve,” but he thinks it can improve with the release of iOS 6 this autumn. How accurate has Siri been for you?
