After the search has been executed, the results may be heard either as a list of websites, or by subject. Using voice commands, the user can navigate to the desired site, and listen to its content.
Google Voice Search from Google Labs (no longer available) provided voice-activated search via the telephone. Yahoo by Phone allows you to speak your commands into the telephone and receive e-mail, news, weather and other info but does not allow you to search the web. The new version of Opera also offers some voice-activated options.
