Hey Siri on iPhone SE: Turn It On

This guide shows you how to enable “Hey Siri” on any iPhone SE (1st, 2nd, or 3rd generation) so you can summon Siri hands-free. You’ll need your iPhone, your Apple ID password (for some settings), and a few minutes. The process is the same across all iPhone SE models running iOS 13 or later.

What You’ll Need

Your iPhone SE with the latest iOS version installed (check Settings > General > Software Update).
Your Apple ID password (you may need it to confirm settings changes).
A stable internet connection (Siri requires a network to process requests).

Step-by-Step

Open Settings. Tap the gray gear icon on your home screen.
Tap “Siri & Search.” Scroll down the Settings list and select “Siri & Search.” It’s usually near the top, between “Accessibility” and “Control Center.”
Enable “Listen for ‘Hey Siri’.” Tap the toggle switch next to “Listen for ‘Hey Siri’” so it turns green. If this is the first time you’re enabling it, a setup screen will appear.
Complete the voice setup. When prompted, tap “Continue” on the “Set Up ‘Hey Siri’” screen. You’ll be asked to say a few phrases like “Hey Siri, it’s me” and “Hey Siri, how’s the weather today?” Speak clearly and naturally, holding the iPhone about 6–12 inches from your face. Tap “Done” when finished.
Confirm the toggle is on. After setup, the “Listen for ‘Hey Siri’” switch should remain green. If it’s off, tap it again and repeat the setup.
Test it. Press the Home button (or side button on SE 2nd/3rd gen) to wake your iPhone, then say “Hey Siri, what time is it?” Siri should respond with a chime and display the answer.

Common Mistakes

Skipping the voice setup. Some users toggle the switch off and on quickly, which cancels the setup. Always complete the voice enrollment phrases.
Mumbling or speaking too softly. “Hey Siri” works best when you speak clearly and at a normal volume. Whispering often fails.
Having Siri disabled entirely. If “Hey Siri” won’t turn on, check that Siri itself is enabled. Go to Settings > Siri & Search and make sure “Press Home for Siri” (or “Press Side Button for Siri”) is on.
Forgetting to allow Siri when locked. If you want “Hey Siri” to work while your iPhone is face down or in your pocket, you need to enable “Allow Siri When Locked.” This is a separate toggle in the same Siri & Search menu.
Assuming it works with low power mode. Low Power Mode does not disable “Hey Siri,” but it may reduce responsiveness. If you’re in Low Power Mode and it seems slow, that’s normal.

Tips

Re-train Siri if it doesn’t recognize you. Go to Settings > Siri & Search > “Listen for ‘Hey Siri’” and toggle it off, then on again. This will restart the voice setup and can improve recognition.
Keep your iPhone’s microphone clear. A dirty or blocked microphone (often from a case) will make “Hey Siri” unreliable. Clean the mic holes gently with a dry soft brush.
Use “Hey Siri” with the screen off. On iPhone SE, you can say “Hey Siri” even when the screen is off, as long as “Allow Siri When Locked” is enabled. This is great for hands-free use while driving or cooking.
Change Siri’s voice or language. If Siri doesn’t understand your accent, try changing the language or voice in Settings > Siri & Search > Language or Siri Voice. This can improve recognition.
Check for iOS updates. Apple frequently improves Siri’s voice recognition. Keeping your iPhone updated can fix bugs that affect “Hey Siri.”

Troubleshooting

If “Hey Siri” still doesn’t work after following the steps above, try these fixes in order:

Restart your iPhone. Press and hold the side button and either volume button until the power off slider appears. Slide to power off, wait 30 seconds, then turn it back on.
Check microphone function. Open the Voice Memos app and record a short clip. If you can’t hear playback, your microphone may be damaged or blocked. Try removing any case or screen protector.
Reset Siri settings. Go to Settings > Siri & Search and toggle off “Listen for ‘Hey Siri’,” then toggle it back on. Complete the voice setup again.
Reset all settings. Go to Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings. This won’t delete your data, but it will reset Wi-Fi passwords, wallpapers, and Siri settings. You’ll need to re-enable “Hey Siri” afterward.
Check for restrictions. Go to Settings > Screen Time > Content & Privacy Restrictions. If Siri is restricted, you’ll see a message when trying to enable it. Turn off the restriction or enter your Screen Time passcode.
Update iOS. Go to Settings > General > Software Update. If an update is available, install it. Siri bugs are often fixed in updates.
Contact Apple Support. If none of the above works, there may be a hardware issue with the microphone or the device itself. Contact Apple Support or visit an Apple Store for diagnostics.

Frequently Asked Questions

Does “Hey Siri” work on all iPhone SE models?

Yes, all iPhone SE models (1st, 2nd, and 3rd generation) support “Hey Siri.” The feature has been available since iOS 8, and the iPhone SE (1st gen) shipped with iOS 9, so it’s fully supported.

Why does my iPhone SE say “Hey Siri” isn’t available?

This usually happens if Siri is disabled entirely, or if the device is in a region where Siri isn’t supported. Check that “Press Home for Siri” is enabled, and ensure your iPhone’s region and language settings match a supported Siri language.

Can I use “Hey Siri” while the iPhone is charging?

Yes, “Hey Siri” works while charging, as long as the microphone is not obstructed. Some users find it works better on a flat surface.

Will “Hey Siri” drain my battery?

It uses a small amount of battery because the iPhone is always listening for the trigger phrase. Apple has optimized this to be minimal, but if you’re concerned, you can turn it off when not needed.

Can I change the “Hey Siri” trigger phrase?

No, the phrase is fixed to “Hey Siri.” You cannot customize it to something else. However, you can change Siri’s language and voice to better match your accent.

What if Siri doesn’t respond to my voice but responds to others?

This is likely a voice recognition issue. Go to Settings > Siri & Search > “Listen for ‘Hey Siri’” and toggle it off and on to retrain. Speak clearly during setup, and avoid background noise.

General steps for current mainstream versions; menus can differ by device and version. See the disclaimer or report an error.
