Using only your voice, Apple’s Voice Control enables you to navigate your iPhone, start apps, transcribe text, and access particular capabilities.
Apple provides a range of accessibility tools to make using your iPhone easier. Use your voice as a substitute if you’re unable to use your phone by hand. You can explore the screens of your phone, launch apps, enable particular features, and alter settings by turning on voice control. This is how it goes.
You need iOS 13 or later to use voice control on your iPhone. The iPad, running any version of iPadOS, has the same option accessible. Go to Settings > General > Software Update to find out what operating system version you are currently using. You’ll either be informed that your OS is current or asked to install the most recent update.
Set Up Voice Control

Go to Settings > Accessibility > Voice Control to enable voice control. Activate the voice control switch. The language is also selectable here. The Command Feedback section is where you should look to decide what, if any, reaction you want when a voice command is given.

Before a command is executed, Show Confirmation requires your response to a confirmation notice. When you use the voice command Play Sound, a sound is played. Additionally, if you mispronounce your voice command, Show Hints will display a hint. Until you get the hang of using voice control, you might wish to turn on all three switches.

To examine and edit the various voice commands, select Customize Commands. To examine the various phrases you can use to launch a voice command, choose a category and then choose a specific one. Each command can also be enabled or disabled, and you can choose whether or not a confirmation is needed.
Voice Commands

You can now test out a few voice commands to see how the feature functions. If you’re having trouble coming up with something to say, look for ideas in the commands menu. You can use voice commands to navigate your phone, scroll up and down the screen, start apps, and access important functions like Siri, the Control Panel, and the App Switcher.

You will get a notification box following the issuance of a voice command if you have voice commands set to demand a confirmation. To confirm the action and move on, say “tap confirm.”
Voice Dictation

You can also use voice control to navigate the screen in any text app and dictate text. When you enable Voice Control, Dictation Mode is activated automatically. Start dictating the text while using an app such as Mail, Messages, Notes, or Reminders.

Additionally, you can navigate the screen and voice-edit text with Voice Control. Under Text Selection, Text Editing, and Text Deletion, editing instructions are displayed.

Command Mode vs. Dictation Mode

Saying “command mode” will make everything you say when dictating text be interpreted as a command, allowing you to move across the screen, pick text, and modify text without your commands being accidentally recorded as text.
Say “dictation mode” to begin typing words if you are using commands to navigate and are ready to begin writing or revising your words. Then your words will be translated into text.
Create Custom Command

If you touch Customize Commands > Build New Command, you may create your own unique voice command. Enter your spoken words in the Phrase field. To select whether this command will input text, perform a specific gesture, or launch a shortcut, tap Action. Then, you can type something in, make a gesture, or select a certain shortcut.

Leave the Application option set to Any if you want the command to work in any app. Otherwise, pick a certain app. Tap Save when finished. To make sure your custom voice commands function, test each one. Ensure that each one has confirmation turned on so you can check to see if your voice command was acknowledged.
Add Words to the Vocabulary

You can add a term to the vocabulary list if the Voice Control function is unable to grasp it. Accessibility > Voice Control > Vocabulary should be opened. In the Add New Entry section, input the term you want to add, press the plus (+) icon in the top-right corner, and then tap Save.

You can instruct your phone to speak a word if Voice Control is unable to comprehend a word you added to its dictionary. Accessibility > Spoken Content > Pronunciations under Settings. Type the word by tapping the plus (+) sign. To check your pronunciation, speak the word into the microphone icon and then tap Play to hear it back.
Add Overlay

On your screen, you can show a grid with distinct numbers or names for each section. Then, you can locate a specific place on the screen by its grid number or name if you want to activate or control it. To configure this, go to Settings > Accessibility > Voice Control > Overlay and select whether you want to see item names, item numbers, or a grid of numbers.
You can adjust the dimming and opacity if you choose item names or numbers. You can customize the numbered grid’s dimmer, opacity, and number of rows and columns.

You will now see your selected grid overlay when you launch a screen. Since each icon has a distinct number, the Home screen is an ideal choice for usage with a numbered grid. Say “tap 10” or “tap 14” to tell your device to tap the number that corresponds to the app you want to open. You can choose a choice in the app you’ve just opened by saying a command to tap the relevant number.
