Use Sound Recognition on iPhone (iOS 14)

Sound Recognition on iPhone (introduced in iOS 14) lets your phone listen for specific sounds—like a smoke alarm, doorbell, or baby crying—and notify you when it hears them. This is especially helpful for people who are deaf or hard of hearing, or anyone who wants an extra alert for important sounds. You’ll need an iPhone that supports iOS 14 or later (iPhone 6s and newer) and the Settings app. No additional downloads are required.

What You’ll Need

• An iPhone running iOS 14 or later (check in Settings > General > About > iOS Version)
• Access to the Settings app (pre-installed)
• Optional: a paired Apple Watch to receive notifications if you want them on your wrist

Step-by-Step

1. Open Settings. Tap the gray gear icon on your home screen.
2. Go to Accessibility. Scroll down and tap “Accessibility.”
3. Select Sound Recognition. Under the “Hearing” section, tap “Sound Recognition.”
4. Turn on the main switch. Tap the toggle next to “Sound Recognition” so it turns green. A pop-up will explain that your iPhone will listen for sounds and that this feature may affect battery life. Tap “OK” to continue.
5. Choose the sounds you want to detect. Below the toggle, you’ll see a list of sounds: Fire Alarm, Siren, Smoke Alarm, Cat, Dog, Applause, Baby Crying, Coughing, Doorbell, Door Knock, and Water Running. Tap the toggle next to each sound you want to enable. A green toggle means it’s active.
6. Review notifications. When a sound is detected, you’ll get a notification with the sound name and a timestamp. To see these later, open the Notification Center (swipe down from the top-left or top-center).
7. Test it (optional). Play the sound you enabled (e.g., a doorbell video) and wait a few seconds. You should see a notification appear. If not, check the troubleshooting section below.

Common Mistakes

• Enabling the main toggle but not individual sounds. The main switch must be on, but you also need to turn on at least one specific sound. If no sounds are selected, the feature does nothing.
• Expecting it to work through headphones. Sound Recognition uses the iPhone’s built-in microphone. If you have AirPods or other headphones connected, the iPhone may use the headphone mic, which can miss sounds from the room. Disconnect headphones for best results.
• Thinking it records audio. Sound Recognition processes audio on-device and does not record or save sound clips. It only sends a notification when a match is found.
• Battery drain concerns. Leaving it on all day will use more battery. It’s not a huge drain, but if you’re low on battery, consider turning it off when you don’t need it.

Tips

• Use it with Do Not Disturb. Sound Recognition notifications still appear even if your phone is on silent or Do Not Disturb, so you won’t miss important alerts.
• Set custom notification sounds. In Settings > Notifications > Sound Recognition, you can choose a unique alert tone so you can distinguish it from other notifications.
• Pair with an Apple Watch. If you have an Apple Watch, the notification will also appear on your wrist, which is handy if your phone is in another room.
• Combine with Focus modes. You can allow Sound Recognition notifications even when a Focus mode is active, so you stay alert during work or sleep.
• Keep your microphone clear. Make sure the bottom of your phone isn’t covered by a case or your hand, as that’s where the mic is.

Troubleshooting

• No notifications at all. First, check that both the main toggle and at least one sound toggle are green. Then, go to Settings > Notifications > Sound Recognition and make sure “Allow Notifications” is on. Also, check that your phone isn’t in a Focus mode that blocks notifications.
• Detects sounds too often or too rarely. The feature is designed to be conservative. If it’s missing sounds, try placing your phone closer to the source or in a more central location. If it’s over-triggering, move the phone away from background noise like a TV or fan.
• Battery drains quickly. Sound Recognition constantly listens, which uses power. Turn off sounds you don’t need, and disable the feature entirely when you’re in a quiet place or have your phone plugged in.
• It doesn’t work when the phone is locked. It should work when locked, but if it doesn’t, make sure your phone isn’t in a low-power mode that disables background listening. Also, check that the microphone isn’t blocked by a case.
• After an iOS update, it stops working. Go to Settings > Accessibility > Sound Recognition and toggle it off and on again. This often re-initializes the feature.

Frequently Asked Questions

Does Sound Recognition record audio?

No. It processes sounds in real time on your device and only sends a notification when it detects a match. It does not save or store any audio clips.

Will it work with any smoke alarm or doorbell?

It’s designed to recognize common patterns, but it may not catch every brand or model. Test it with your specific devices. For critical alerts, always rely on dedicated detectors.

Can I add custom sounds?

No, iOS 14 only offers the built-in list of sounds. You cannot train it to recognize your own custom sounds.

Does it work in all countries?

Yes, the feature is available globally, but the exact list of sounds may vary slightly by region. The core functionality is the same.

Will it drain my battery a lot?

It does use extra battery because it’s constantly listening. Most users notice a modest increase in usage. You can turn it off when you don’t need it.

Can I use it while on a phone call?

No, Sound Recognition pauses during calls because the microphone is in use for the call. It resumes after you hang up.
