Website voice commands

If you own a website and want to provide voice commands for those users that have installed the Handsfree for Web extension, you can export the commands and make them available.

Similar to the commands definition of the modules, a website voice command is described as a name and an action that will be executed once the command is pronounced by the user.

In order to tell to the extension the available commands, it's necessary to execute a global function called handsfreeCommands and share with it via a parameter the command list.

Setting website voice commands

window.onload = function() {
  handsfreeCommands([{
    name: 'open contact section',
    help: 'Opens the contact section of this website',
    group: 'Website sections'
    action: function() {
      window.location.href = '/contact.html';
    }
  }, {
    name: 'open home page',
    help: 'Opens the home page of this website',
    group: 'Website sections'
    action: function() {
      window.location.href = '/';
    }
  }]);
};
                    

There is no context for the website commands, they are allowed to be executed at any time and they have precedence over the commands supported by the application and those were imported via a custom module.

Since the website commands are not part of a context, probably you will need to update the available commands depending of the user interaction. For example, if the user opens a section, a new list of voice commands must be provided. The function handsfreeCommands can be called multiple times with the latest available voice commands.

Here the website voice command properties.
