Has Google Now ever misheard a word you meant to say?
Chances are, it has. Although the service is pretty damn accurate, it’s still a developing technology and has a ways to go before being perfect. Google knows its product isn’t perfect, and in addition to improving voice recognition in Google Search, it has now added a “no I said ___” command for when the app mishears something you said.
For example, if you were to say, “Show me the nearest bars,” and Google heard, “Show me the nearest cars,” you could simply start up a new command and say, “No I said bars.”
Google Search would replace “cars” with “bars,” and continue the originally intended search.
This adds a very natural interaction to Google Now’s arsenal, and you can expect more commands just like this one to be added to the app in the near future.
