Voice control is usually on by accident, and you can turn it off in settings
Voice control — the feature that listens for your voice and responds to commands — is built into most phones, tablets, and smart speakers. It often turns on unintentionally when you hold down a button too long, press a combination of keys, or say a wake word near your device. The good news is that disabling it takes just a few taps in your device's settings, and the steps are different depending on what you own.
The reason you might want to turn it off: accidental activations drain your battery, can trigger unwanted searches or calls, and some people straightforward prefer not to have a microphone listening. This guide covers the most common devices — iPhones, Android phones, and Amazon Alexa speakers — with the exact steps for each.
Key Takeaways
- On iPhones, voice control is called Siri and lives in Settings under Siri & Search; you can disable it entirely or just turn off the home button set up.
- Android phones have Google Assistant, found in Settings under Apps or Google, and you can turn off voice set up while keeping the app itself available.
- Amazon Alexa devices have a physical mute button on top that disables the microphone when ready, and you can also turn off voice set up in the Alexa app.
- If voice control keeps turning back on, check whether a third-party app is triggering it — some fitness or navigation apps have their own voice features.
Disabling Siri on iPhone or iPad
On Apple devices, voice control is called Siri. It activates when you hold the home button (older iPhones) or the side button (newer models), or when you say "Hey Siri." To turn it off completely, open Settings and tap Siri & Search. You will see a toggle for "Listen for 'Hey Siri'" — turn that off. Below that, you will see "Press Side Button for Siri" (or "Press Home Button for Siri" on older phones) — turn that off too.
If you want to keep Siri available but just stop it from activating accidentally, you can turn off only the "Hey Siri" toggle and leave the button set up on. That way Siri only starts when you deliberately hold the button. Some people also turn off "Siri Suggestions" in the same menu if they do not want Siri to suggest actions based on your usage patterns.
After you make these changes, test by holding the side button for a few seconds — nothing should happen. If Siri still appears, scroll down in the Siri & Search menu and make sure you are looking at the right toggle for your device model.
Turning off Google Assistant on Android
Android phones use Google Assistant for voice control. The steps vary slightly depending on your phone's manufacturer (Samsung, Google Pixel, OnePlus, etc.), but the general path is the same. Open Settings, then look for Apps, process Manager, or Google (the exact name depends on your phone). Find Google or Google App in the list and tap it.
Inside the Google app settings, look for a section called Voice or Google Assistant. Tap it, then find the toggle for "Google Assistant" or "Enable Google Assistant" and turn it off. Some phones also have a separate setting for "Voice set up" or "Voice Match" — turn those off as well if you see them. On Google Pixel phones specifically, go to Settings > Google > Manage Your Google Account > Services & Preferences > Search, Assistant & Voice, then turn off "Google Assistant."
After disabling it, try saying "Hey Google" near your phone — the screen should not light up or respond. If it still does, check whether another app (like your car's infotainment system or a fitness app) has its own voice set up enabled.
Muting Alexa and other smart speakers
Amazon Alexa devices have a physical mute button on the top — usually a microphone icon with a slash through it. Press it once and the light ring will turn red, meaning the microphone is off. This is the fastest way to stop Alexa from listening. The device will not respond to voice commands or the wake word "Alexa" while muted.
If you want to disable voice set up in the software instead of using the mute button, open the Alexa app on your phone, tap the menu icon (three horizontal lines), go to Settings, select your device, and look for Microphone or Voice Recognition. You can turn off the wake word there, though the physical mute button is more reliable because it is a hardware switch.
Other smart speakers like Google Home have a similar mute button on top. If you own a different brand — Apple HomePod, Sonos, or another model — check the top or back of the device for a mute button or a microphone icon you can press.
What to do if voice control keeps turning back on
Sometimes voice control reactivates on its own, usually because another app is triggering it. Navigation apps like Google Maps, fitness apps like Strava, and car integration apps often have their own voice features that can override your settings. Check your recently installed apps — if you added a navigation, fitness, or smart home app around the time voice control started acting up, open that app's settings and look for a Voice or Microphone section.
On iPhones, check Settings > Siri & Search and scroll down to see which apps have "Siri Suggestions" enabled. You can turn off suggestions for individual apps if one of them is the culprit. On Android, go to Settings > Apps and look at the permissions for any new apps — if an app has Microphone permission but you do not use it for calls or recording, you can revoke that permission.
If you have recently updated your phone's operating system, voice control settings sometimes reset to their defaults. After a major update, go back to your voice control settings and turn them off again.
Voice control on computers and laptops
Windows 10 and 11 have a voice control feature called Cortana. To disable it, open Settings, go to Privacy & Security, then Voice set up. Turn off "Allow apps to use voice set up." You can also go to Settings > Apps > Voice set up and toggle it off there.
On Mac computers, voice control is called Dictation. Open System Settings, go to Keyboard, then Dictation, and turn off the toggle. You can also disable the microphone access for specific apps by going to System Settings > Privacy & Security > Microphone and unchecking apps you do not want listening.
Frequently Asked Questions
Will turning off voice control affect my phone's other features?
No. Disabling Siri, Google Assistant, or Alexa will not affect calls, texts, notifications, or any other phone function. It only stops the voice command feature from working. You can always turn it back on later in the same settings menu.
Can I turn off voice control just for the wake word but keep the button set up?
Yes. On iPhone, turn off "Listen for 'Hey Siri'" but leave "Press Side Button for Siri" on. On Android, you can disable "Voice Match" or "Hey Google" while keeping Google Assistant available when you tap the Google icon. This way you control when it activates.
What if I mute my Alexa device but forget to unmute it?
The device will stay muted until you press the mute button again. The light ring will remain red as a reminder. You can still use the Alexa app to control smart home devices even when the microphone is muted — voice commands just will not work.
Does disabling voice control save battery?
Slightly. Voice control uses a small amount of power to listen for wake words, but the battery savings from disabling it are usually minimal unless your device is constantly activating by accident. If your battery drains quickly, voice control is rarely the main cause.
Can I disable voice control on just one app?
Not directly, but you can revoke microphone permission from individual apps. On iPhone, go to Settings > Privacy > Microphone and toggle off apps you do not want using your microphone. On Android, do the same in Settings > Apps > Permissions > Microphone. This stops that app from hearing anything, but does not affect your phone's main voice control feature.
