Automatically clicking a pre-defined region on a webpage?

I'm trying to do something with Chrome's new speech reco开发者_Python百科gnition abilities with HTML5.

Following this page: http://www.filosophy.org/2011/03/talking-to-the-web-the-basics-of-html5-speech-input/ I see that you can easily hide the input area. But I'd like to take this further and automatically click the mic button (using javascript is possible?) without waiting for the user to click it.

Since the mic button resides on a specific region in the page always (dictated by me), is there a way to automate a click on a particular region on the webpage? So that the form doesn't wait for the user to click the button to populate itself. I'm guessing this should be possible with JS?

Please let me know, thanks :)

No, this is impossible for the same reason that you can't populate the value of a file input.

If you can turn the mic on without the user explicitly agreeing to it, then you could spy on what was being said near that mic.

For security reasons, this will never be possible.
