????Siri有點像天氣。人人嘴上都愛抱怨它，但只有投資銀行Piper Jaffray的吉恩?蒙斯特真正采取了行動。

????今年六月，蒙斯特測試了iOS 5版本的蘋果（Apple）聲控個人助理Siri。他向Siri問了1,600個問題，其中有800個問題是在美國明尼阿波里斯市的街頭問的，而另外800個則是在一間安靜的房間中問的。

????結果顯示Siri尚有很大的改進空間。在最理想的情況下（即沒有街道噪音），Siri正確理解了89％的問題，正確回答了68％的問題。（一個很典型的例子是，Siri聽見問：下次哈雷彗星出現是什么時候？它的回答是：“您沒有安排與哈利會面。”

????上周四，明斯特報道了在安靜的房間（沒有街道噪音）里對“改進后的”iOS 6版Siri再度進行測試的結果。這一次，Siri理解了91％的問題，并正確回答了77％的問題。

????按照學校的打分標準，Siri的得分從D提高到了C。

????（明斯特沒有解釋他為何將Siri在六月份的正確率從68％調高到了76％，從而使得iOS 6版Siri的進步看起來小了很多。或許他現在是按正態曲線評分了。）

????Siri is a little like the weather. Everybody complains about it, but only Piper Jaffray's Gene Munster seems to do anything.

????In June he put the iOS 5 version of Apple's (AAPL) voice-activated personal assistant to the test -- asking her 1,600 questions,800 in the streets of Minneapolis and 800 in a quiet room.

????The results left much to be desired. In the best of circumstances (i.e. no street noise), Siri correctly interpreted 89% of the questions and correctly answered 68%. (Typical exchange, as Siri heard it: When is the next Haley's comment? "You have no meetings matching Haley's".)

????On Thursday, Munster reported the results of a quiet-room (no street noise) re-test of the "improved" iOS 6 version. This time Siri understood 91% of the questions and correctly answered 77%.

????In school-grade terms, she's gone from a D to a C.

????(For reasons Munster doesn't explain, he's raised Siri's June score from 68% to 76%, making the improvement look more modest than it was. Perhaps he's now grading on a curve.)
