How to Turn Off Voice Control on Your iPhone: 5 Steps

Voice Control on your iPhone _tries_ to be helpful, letting you place calls or play music just by saying what you want. However, not everyone agrees or finds it useful. While Apple makes no provision for actually disabling voice control, there are ways around that. This article will show you how.

5

TURN VOICE DIAL OFF. After you've enabled your passcode, tap the Voice Dial toggle to flip it from On to Off. While you cannot totally disable Voice Control, this will at least disable it when your screen is locked.
Note: if you disable the passcode, Voice Control will automatically be enabled from the lock screen. [1]
TIPS
If you have an iPhone 4S or later, activating Siri will de-activate Voice Control. (NOTE: This only turns off Siri and turns the normal voice control back on!)
If you must totally disable Voice Control, you can jailbreak your iPhone, and use a hack.
