Speech input has been implemented in Chrome 11. Click the input box's microphone icon and start speaking!
Your browser does not support webkit speech so a standard input box will be shown.
Speech support can be implemented with the following code:
<input type="text" x-webkit-speech />
The x-webkit-speech attribute can be used on any HTML5 input with the type text, number, tel, or search.
This example code was developed by Craig Buckler of OptimalWorks.net for SitePoint.com.
