To say a voice command to start an action
1When Voice Dialer prompts you with voice command examples such as to call a contact, say the command that includes the name of the contact you want to call. For example, if you want to call a contact named John, use this command Call <Name> and say “Call John” to your device.
2Once your device recognizes your command, it automatically lists the matching actions. You can now choose to call a contact or open an application from the list.
