Siri is Apple's intelligent virtual assistant. It responds to "Hey Siri" or a button press. However, you may come across when Siri is not working on iPhone. No matter how many times you have called, Siri does not respond. This article is here to help you solve this problem. We will analyze the possible causes and provide the corresponding solutions for you.

Part 1. Why Is Siri Not Working on iPhone

Siri can be a powerful and helpful assistant that helps you deal with various tasks on your iPhone. However, it may sometimes go wrong, and cannot respond to your call. Here, we list several reasons why Siri is not working.

1. Your Siri is not activated.

2. Your iPhone fails to connect to the Internet. Or the network connection is unstable or weak.

3. Your iOS is outdated.

4. The Do Not Disturb mode on your iPhone is on.

Part 2. How to Fix Siri Not Working on iPhone

As we have discussed the possible reasons that cause Siri's not responding in part 1, we can fix this problem by checking these causes.

Check Your Siri's Settings

You first need to enable Siri before you call it. If you haven't turned on the Listen for "Hey Siri", saying hey Siri doesn't work. Besides, if the Allow Siri When Locked option is not turned on, Siri still can't work if your iPhone is locked.

Step 1. Go to Settings > Siri & Search.

Step 2. Turn on these options: Listen for "Hey Siri", Allow Siri When Locked, and Press Side Button for Siri (or Home Button, for iPhone 8 Plus or older iPhones)

Check Your network

Siri needs an Internet connection to work. If your iPhone won't connect to Wi-Fi or your network is unstable or weak, it is possible to cause the Siri not responding problem.

Step 1. Go to Settings > WiFi.

Step 2. Check if you have turned on WiFi. If not, turn it on and connect to your Wi-Fi.

Step 3. Try if you can load a web page in Safari. If not, it indicates that your Wi-Fi is unstable or weak. You need to change the network.

Update the iOS

Outdated iOS can stop Siri from working. Apple updates iOS to fix bugs and improve user experience, which may resolve the Siri not working problem.

Step 1. Go to Settings > General > Software Update.

Step 2. Check if your iPhone has updated to the latest version. If not, update.

Turn off the Do Not Disturb Mode

The Do Not Disturb mode silences calls, alerts, and notifications to avoid interruptions. If it is on, Siri may be blocked from responding.

Step 1. Go to the Control Center.

Step 2. Check if your iPhone's Do Not Disturb is on. If it is on, turn it off.

Retrain Siri to Recognize Your Voice

It is possible that Siri can't recognize your "Hey Siri" voice. It may detect your voice as a stranger, and thus, it won't respond, which makes Siri not work. In that case, you need to retrain Siri to familiarize it with your voice.

Step 1. Go to Settings > Siri & Search.

Step 2. Turn off Listen for "Hey Siri" option, and then turn it on.

Step 3. Follow the instructions shown on the screen to retrain your Siri.

Check the Microphone

If something (e.g., dirt, case, debris) blocks your iPhone's microphone, it may cause Siri not be able to hear you. When this happens, Siri does not respond to your voice.

Step 1. Clean your microphone to ensure that there's no dirt, case, or debris.

Step 2. Test your microphone by recording a voice memo to see whether your microphone can function normally. If it can't, contact Apple Support.
