Do It Yourself
There are several ways of defining your own voice commands for Opera actions. By editing the voice setup being used, you can change the existing commands, you can add new commands for new actions, or you can do both. Duplicate the existing setup before modifying it to keep a backup of the original settings. Note that the dialog that allows you to create or modify commands also allows you to modify the prefix that must be spoken before commands. You can either select one from the list, or type in the box to add an alternative.
To define your first custom command, try adding a short voice command for going to one of your favorite Web sites: Click on the "Application" input context, then click "New" and fill out the voice command you would like to use, for example "cool". Then press Tab or click to go to the action field. Press G, and a list of all available browser actions starting with G should drop down. Get the action "Go to page" and change it to look something like the following:
Go to page, "http://example.com/"
Type the desired Web address and remember to close the quotation marks. Press Enter and exit the preferences.
Now try out your brand new voice command; press the voice button and say "Opera cool". If it is not recognized, try having a look at the Helpful Hints section or the Troubleshooting Opera with Voice page.
You can make as many custom commands as you like, but bear in mind that a very long list of extra commands is likely to slow voice browsing down significantly.
Tip: Go to "Customize toolbars" to rid the browser interface of toolbars and buttons that you replace with voice commands.
