Use voice commands to control your device and access voice control settings.
ACCESS VOICE CONTROL: From the home screen, select the Microphone icon in the Google search bar or say "OK Google".
When "Listening..." is present onscreen, speak what you would like to search for and Google will begin the search.
Note: You can use your voice to do things like search, get directions, create reminders, identify a song, send a text message, and call a friend. For example, say "Ok Google, do I need an umbrella tomorrow" to see if there's rain in the weather forecast.
