Google has had a pretty big year in terms of improvements. First, they introduce +1 and now they introduce voice search for desktop. While voice search has been a big part of Android for years, desktop users have had to stick to typing. Google used all of the voice data it has been collecting on Android to hone desktop search into a well-oiled machine.
The effectiveness of voice search is surprisingly good. Google is leading the pack when it comes to voice recognition. Despite trying to stump it with uncommon words, out of the 50 or so times I used voice search it only misheard me twice. This includes searches involving names and book titles. It’s clear that Google has been putting all those mobile voice searches to good use.
