The Bits blog takes another look at Siri's rival. Loved this part:
If Google is better, it is most likely because it has roots in a product Google introduced in 2007, called Google-411, or Google Local Voice Search. Ostensibly a product that provided free directory assistance, Google was mostly interested in capturing the way different people pronounced words.
Reminded me of how we have also been helping, again mostly unaware, to clean up their scanned corpus.
