Google Voice Search available for desktops
Now Google has made available Voice Search for desktops. The service can be used by simply clicking the microphone icon next to the search bar on google.com.
We can talk instead of typing in the Google search engine. You just need a version of Chrome 11 or higher and a microphone available in your computer.
If once on google.com you still can not see the microphone icon, you can go to google.com/experimental/ and join the Voice Search experiment, so you can try it while it becomes available in your zone. Remember, Voice Search is available only in English at this point.
