Question 3: "How tall is the Taipei 101 tower?"
Siri completed in: 3.7 seconds
Siri responded to our question by providing an information card with the total height of the tower in feet and its world ranking, as well as a series of unit conversions.
S Voice completed in: 8.3 seconds
The Galaxy S III's S Voice used WolframAlpha to search for Taipei 101 and came back with an information card complete with its height in feet, as well as a more thorough conversion chart than Siri's and comparisons to the CN Tower and Eiffel Tower.
Google Voice Search completed in: 3.3 seconds
Google Voice Search pulled the answer for this question from two sources: Answers.com for a photo of the tower and Wikipedia for the height in feet and meters.
Winner: Google Voice Search. While it didn't offer a conversion chart, Google's Voice Search edged out Siri and S Voice in this round thanks to its inclusion of a photo of Taipei 101 and its faster response time.
Question 4: "Did the New York Mets win last night?"
Siri completed in: 6.72 seconds
In our test, Siri was unable to give us an answer to give us the score of last night's Mets game. We therefore assume that it's a Yankees fan. It's worth noting, however, that Siri will receive a significant update, including the ability to provide sports scores, when iOS 6 is released.
