The following can be considered as the main reasons behind the non-working of Siri:
1. Clear the iPhone’s RAM
If there’s a background data build-up on the iPhone’s RAM and is glitching the phone’s RAM, then the glitched RAM may not let Siri execute properly. Here, clearing the iPhone’s RAM may clear the Siri issue. For iPhone 8 & Below: For iPhone X and Above:
2. Disable the ‘Do Not Disturb Mode’ of the iPhone
If the iPhone is in its Do not Disturb mode, then it may hinder the operation of Siri as modules essential for Siri may be disabled in the DND mode. In this scenario, disabling the Do Not Disturb mode of the iPhone may solve the problem. For iOS 15 Devices: For iOS 14 & Below Devices:
3. Perform a Force Restart of Your Device
A temporary glitch in the OS modules could stop Siri from working as Siri fails to access the modules essential for the Siri operation. In this context, performing a force restart of your device may clear the Siri error at hand. Although this article mainly covers the steps for an iPhone, the same steps can also be used on other Apple devices.
4. Disable and Enable Siri in the Device’s Settings
A temporary glitch in the Siri modules may not let you properly access Siri and its related features. In this case, disabling and enabling Siri in the device’s settings may solve the problem. In the case, the issue is occurring with an Apple TV, check if connecting an audio output device to the TV (if the TV does not have speakers) resolves the issue.
5. Update the Device’s OS to the Latest Build
If your device’s OS is not updated to the latest build, then its incompatibility with the latest features of other services (like Siri) could cause the non-working of Siri as Siri may fail to query the Apple servers. In this context, updating the device’s OS (like an iPhone) to the latest build may solve the problem. Before proceeding, backup your phone, fully charge it, and connect it to a Wi-Fi network.
6. Clean Your iPhone
If debris or dust has accumulated around the mic used by Siri, then Siri may fail to “understand” your command and thus may not execute it. In this case, cleaning your iPhone, especially the mic area, may solve the problem.
7. Set Siri to Respond Always
If the Siri feature is not configured to respond always, then that may cause the issue at hand as Siri may ignore different commands under different circumstances (like in handsfree mode). In this context, setting Siri to respond always may solve the problem.
8. Disable and Enable Dictation of the Device
Siri may fail to work properly if the dictation feature of the iPhone’s keyboard is disabled as Siri relies on some of the dictation modules to execute properly. Here, enabling (or disabling/enabling) the dictation feature of the iPhone’s keyboard settings may solve the problem.
9. Disable Type to Siri in the Device’s Accessibility Settings
If the ‘Type to Siri’ in the device’s settings is enabled, then Siri may not respond to voice commands as it is waiting for a command through typing. Disabling the ‘Type to Siri’ in the device’s accessibility settings may solve the problem.
10. Disable VPN on the iPhone
If your iPhone is routing its traffic from a VPN, then the VPN’s non-compliance with the web traffic generated by Siri can cause the issue at hand. Here, disabling the VPN on the iPhone may solve the problem.
11. Disable Bluetooth of the iPhone
If your iPhone is connected to a Bluetooth device or Siri “thinks” it does, then Siri may keep on waiting to receive commands from that device while ignoring your commands from iPhone’s internal mic, which may result in the Siri issue at hand. In this case, giving commands through the connected Bluetooth device (like a speaker with a mic) or disabling Bluetooth on your iPhone may solve the problem.
12. Disable Noise Cancellation of the iPhone
If your device is configured to cancel the noise from the phone’s audio input, then that may cause the non-working of Siri as Siri’s AI fails to process the altered audio command. Here, disabling the noise cancellation feature of the iPhone may solve the problem.
13. Disable Sound Recognition of the iPhone
The iPhone’s Siri module may fail to work correctly if the iPhone’s Sound Recognition feature is enabled as this feature listens to the surrounding voices around the iPhone and may supersede Siri’s working mechanism. In this context, disabling the Sound Recognition feature of the iPhone may solve the problem. If the issue is occurring with a TV, check if using a different cable like an HDTV clears out the error.
14. Change Siri’s Input Language
If the Siri’s input language modules are glitched out, then the Siri may fail to “understand” the command given. Here, changing Siri’s input language may clear the issue.
15. Change Siri Voice on the iPhone
If the profile of Siri’s voice in use (like the default Female American) is corrupt, then that may not let Siri respond to your command and cause the issue at hand. Here, changing the Siri Voice on the iPhone may solve the problem.
16. Disable Raise to Speak in the Apple Watch Settings
If ‘Raise to Speak’ is enabled in the Apple Watch settings, then the Hey Siri phrase may not activate Siri if your wrist is not raised. In this context, disabling Raise to Speak in the Apple Watch settings may solve the problem.
17. Use the Hardware Button to Enable Siri
A temporary glitch might not let Siri work and firstly activating it through the hardware button may clear the glitch and thus solve the problem.
18. Try Another Network or Network Type
If your ISP is restricting Siri’s access to its servers, then that could result in the Siri issue at hand. Moreover, if the modules of a particular type of network connection (like cellular) are glitched, then that could also result in the problem under discussion. Here, trying another network or network type may clear the Siri issue.
19. Reset Network Settings of the iPhone to the Defaults
Siri might not work if the network settings of your iPhone are corrupt and due to this corruption, Siri fails to properly communicate with the Apple servers. Here, resetting the network settings of the iPhone to the defaults may clear the Siri problem at hand. Before moving on, make sure to note down the network-related information (like the Wi-Fi credentials) that are required later on to set up the network on your phone.
20. Reset All Settings of the iPhone to the Defaults
If an improper configurational change in an iPhone setting is hindering Siri’s ability to work correctly or if an iPhone setting is corrupt, then that may result in the Siri issue under discussion. In this case, resetting all settings of the iPhone to the defaults may solve the problem. Before proceeding, note down the things that may be required later (like Wi-Fi credentials, etc.).
21. Reset the iPhone to the Factory Defaults
If none of the above worked, then the corrupt OS of the iPhone could be the root cause of the Siri issue at hand, and performing the nuke option i.e., resetting the iPhone to the factory defaults may solve the problem. Before proceeding, make sure to backup the essential phone data. If that did not work, then you may contact iPhone support to resolve the Siri issue or get your iPhone checked for a hardware problem. If the issue occurs with an old Apple device, then you may edit its hosts file (at your own risk) to make Siri work for you.
