Google Now just got a bit more robust. Besides the search update that allows users to say “OK, Google” from anywhere in the OS, the personal search assistant can respond to near 52 spoken languages, and even accented variants of languages. However an update now allows Google Now to switch between a total of seven languages at one time.
In order to get it to work, you'll have to pre-select your secondary languages but after that your phone will be able to pick up multiple languages on the fly. Of course, even though 130 million people in the US have used Google Now's voice recognition for search, Google's Tamar Yehoshua has found that it's only a small number of those who could potentially use it. Yehoshua told CNET in a lunchtime interview that, “fifty percent of smartphone and tablet users in the US are aware of voice search, and one-third of those use it.”
The feature is said to be rolling out over the next few days. So if you don't see it yet, be patient. Google is said to be working on voice recognition of children as well, but that won't come for a little while given the safety and legal precautions the company has to wade through to record children.
