Apple's Siri went to a C+ from C, Google Now to a C+ from D-December 10, 2013: 11:39 AM ET
In Piper Jaffray's test of 800 voice queries, Google Now gets the award for most improved.
FORTUNE -- Piper Jaffray's Gene Munster issued a matched pair of report cards Tuesday on the performance of the two leading smartphone intelligent assistants, Google's (GOOG) Google Now and Apple's (AAPL) Siri.
- Google Now has overcome its initial deficit and is now roughly the equivalent of Siri in its ability to interpret spoken queries and answer them correctly.
- Siri has weaned itself almost entirely from its dependence of Google search, reducing its reliance from 27% of answers in December 2012 to 4% now.
- Neither service is that great. Siri got C+ from Munster (up from C last December and a D in the summer of 2012). Google Now also got a C+ (up from a D- last December).
Passing grades, but not much more than that.
