For quite a long time google has been experimenting on the user interface of the homepage.
Now, last week it launched "Voice search". I actually liked it. The google voice extension can be downloaded via. google official voice search link - http://www.google.com/insidesearch/voicesearch.html. Currently it is available for Chrome only. Just speak and the search will be made accordingly.
Even the color of the left navigation bar the serp's page has also been changed to grey. Well I am hoping some more changes in the interface, in terms of color combination and the style of the buttons.
Most of the changes are looking good though, and looks promising, but, can't say what would be final result or will google again stick to the basics.
Let's see what's behind the curtain next.
