Siri can stop working the way it should. Maybe the voice assistant isn’t responding to your commands, keeps misunderstanding what you say, or speaks in the wrong language. Sometimes it gives suggestions that feel completely off or carries voice data you’d rather wipe clean.

Apple doesn’t have a single “reset Siri” button. Instead, the fix depends on what’s actually going wrong. This guide walks through every way to reset, retrain, and troubleshoot Siri on iPhone, iPad, and Mac in 2026. Whether you need to clear Siri’s history, fix voice recognition, or start fresh with a new voice and language, the steps are here.

Why Would You Want to Reset Siri

There are several situations where resetting Siri makes sense. The most common is when Siri simply stops responding to voice commands or the “Hey Siri” wake phrase. This can happen after a software update, a settings change, or seemingly out of nowhere.

Voice recognition problems are another trigger. If Siri consistently misunderstands you or doesn’t recognize your voice at all, retraining the “Hey Siri” model fixes the issue in most cases. The voice model can degrade over time, especially if your speaking patterns or environment have changed.

Privacy is a valid reason too. Apple stores Siri interaction history on its servers for a limited time. If you want to erase that data entirely, you can delete your Siri and Dictation history from Apple’s servers with a few taps.

Other reasons include wanting a different Siri voice, switching languages, or clearing out Siri Suggestions that feel irrelevant. Each of these has its own reset process.

How to Turn Siri Off and Back On (iPhone and iPad)

The simplest reset is toggling Siri off and on again. This forces the system to reinitialize Siri’s services and often fixes problems like Siri not responding, failing to process requests, or showing errors.

1. Open the Settings app on your iPhone or iPad.
2. Tap Siri (on iOS 18 and later) or Siri & Search (on older versions).
3. Turn off Listen for “Hey Siri” and Press Side Button for Siri (or Press Home Button for Siri on older models).
4. A prompt will appear asking if you want to turn off Siri. Confirm by tapping Turn Off Siri.
5. Wait 15 to 20 seconds.
6. Turn both toggles back on. When you re-enable “Hey Siri,” your device will ask you to set up voice recognition again.
7. Follow the on-screen prompts to say several phrases so Siri can learn your voice.

This process clears the active Siri session and reloads the voice assistant from scratch. It’s the first thing to try when Siri acts up, and it resolves most minor glitches without affecting any other settings on your device.

How to Turn Siri Off and Back On (Mac)

The same toggle approach works on Mac, though the setting lives in a different place.

1. Click the Apple menu in the top-left corner and open System Settings.
2. Click Siri in the sidebar (on macOS Ventura and later) or search for Siri in the search bar.
3. Turn off Ask Siri.
4. Confirm when prompted.
5. Wait about 20 seconds, then turn Ask Siri back on.
6. If your Mac supports “Hey Siri” (MacBook Pro 2018 and later, MacBook Air 2018 and later, iMac Pro, or any Mac with Apple Silicon), toggle on Listen for “Hey Siri” and complete the voice training when prompted.

Macs with Apple Silicon (M1 through M4) support always-on “Hey Siri” because they have a dedicated neural engine that listens for the wake phrase without draining battery. Older Intel Macs only support “Hey Siri” when the lid is open and the Mac is connected to power.

How to Retrain Hey Siri Voice Recognition

If Siri doesn’t respond when you say “Hey Siri” or “Siri” (the single-word wake phrase added in iOS 17), the voice recognition model might need retraining. This is especially useful if you’ve changed your speaking habits, moved to a noisier environment, or share the device with someone whose voice was accidentally registered.

Retrain on iPhone or iPad

1. Open Settings and tap Siri.
2. Turn off Listen for “Hey Siri”.
3. Wait a few seconds, then turn it back on.
4. The setup screen appears with five phrases to repeat. Speak each phrase clearly in the environment where you most often use Siri (a quiet room, your car, your office).
5. When all five prompts are complete, tap Done.

Training in the environment where you actually use Siri matters. If you train in a silent room but mostly talk to Siri while driving, the model won’t perform as well in your car. Pick the setting you use most and speak at your normal volume.

Retrain on Mac

1. Open System Settings and click Siri.
2. Turn off Listen for “Hey Siri”, wait a moment, then turn it back on.
3. Follow the voice prompts to record your voice.

How to Delete Siri and Dictation History

Apple associates your Siri requests with a random identifier rather than your Apple ID. Even so, the voice data is stored on Apple’s servers for a period of time to improve Siri’s accuracy. If you want to erase that data, Apple provides a way to do it.

Delete on iPhone or iPad

1. Open Settings and tap Siri (or Siri & Search).
2. Tap Siri & Dictation History.
3. Tap Delete Siri & Dictation History.
4. Confirm the deletion.

Delete on Mac

1. Open System Settings and click Siri.
2. Click Siri & Dictation History (you may need to scroll down).
3. Click Delete Siri & Dictation History and confirm.

Apple states that the deletion request is processed across all servers, though it may take some time to fully propagate. After deleting, Siri won’t have your previous voice data to reference, which means its accuracy might dip slightly until it relearns your patterns through new interactions.

How to Reset Siri Suggestions on iPhone and iPad

Siri Suggestions appear on the lock screen, in search, in the App Library, and in the share sheet. These suggestions are based on your usage patterns. If they’ve become irrelevant or you want a fresh start, you can reset them by resetting location and privacy settings.

1. Open Settings and tap General.
2. Scroll down and tap Transfer or Reset iPhone (or Transfer or Reset iPad).
3. Tap Reset.
4. Tap Reset Location & Privacy.
5. Enter your passcode and confirm.

This resets all app permissions for location access and also clears the behavioral data that Siri uses for suggestions. Apps will ask for location permission again the next time you open them. Siri will rebuild its suggestions from scratch based on your new usage patterns, which typically takes a few days.

You can also turn off Siri Suggestions for individual apps without a full reset. Go to Settings, tap Siri, then tap the specific app. Toggle off Show on Home Screen, Suggest App, and Show in Search for any app you don’t want Siri to suggest.

How to Change Siri Language on iPhone, iPad, and Mac

Changing Siri’s language is useful if you’ve moved to a new country, speak multiple languages, or accidentally set the wrong language during setup. Keep in mind that changing the language also changes how Siri processes your voice, so you’ll need to retrain “Hey Siri” after the switch.

Change Language on iPhone or iPad

1. Open Settings and tap Siri.
2. Tap Language.
3. Select your preferred language from the list. Apple supports over 40 languages and regional dialects.
4. Siri will prompt you to set up “Hey Siri” again in the new language.

Change Language on Mac

1. Open System Settings and click Siri.
2. Click the Language dropdown and pick your language.
3. Retrain “Hey Siri” if prompted.

Some languages offer multiple regional variants. English alone has options for the US, UK, Australia, Canada, India, Ireland, New Zealand, Singapore, and South Africa. Each variant affects pronunciation and accent recognition, so pick the one closest to how you actually speak.

How to Change Siri Voice on iPhone, iPad, and Mac

Apple offers multiple Siri voices for each language. The selection includes different genders, accents, and tonal qualities. Apple expanded the voice options significantly starting with iOS 14.5 and has continued to add new options through 2026.

We walk through iPhone XR step by step in a separate post.

Change Voice on iPhone or iPad

1. Open Settings and tap Siri.
2. Tap Siri Voice.
3. Choose a Variety (accent type, such as American, British, or Australian).
4. Choose a Voice (each variety offers multiple voice options). Tap any voice to hear a preview.
5. The new voice downloads if it isn’t already stored on your device. Download sizes vary but are typically under 150 MB.

Change Voice on Mac

1. Open System Settings and click Siri.
2. Click the dropdown next to Siri Voice.
3. Select your preferred variety and voice.

Voice availability varies by language. English has the largest selection because Apple has invested the most in English-language voice synthesis. Other languages receive new voices with each major iOS release.

How to Fix Siri Not Working on iPhone

If Siri doesn’t respond at all, won’t process your requests, or gives a “something went wrong” error, work through these troubleshooting steps in order. Start with the simplest fixes first.

1. Check your internet connection. Siri requires an active internet connection to process most requests. Open Safari and load a website to confirm you’re online. Some on-device Siri tasks work offline in iOS 17 and later, but the majority still need connectivity.
2. Make sure Siri is enabled. Go to Settings, tap Siri, and verify that both “Hey Siri” and the Side Button shortcut are toggled on. It’s possible to accidentally disable these.
3. Restart your iPhone. Hold the Side Button and Volume Up button simultaneously, then slide to power off. Wait 30 seconds and turn the phone back on. A restart clears temporary system processes that can interfere with Siri.
4. Check for software updates. Go to Settings, tap General, then Software Update. Install any available updates. Apple frequently patches Siri bugs in minor iOS releases.
5. Turn Siri off and on. Follow the toggle method described earlier in this guide. This reinitializes Siri’s services completely.
6. Reset network settings. Go to Settings, tap General, then Transfer or Reset iPhone, then Reset, then Reset Network Settings. This clears saved Wi-Fi passwords and VPN configurations, which can resolve connectivity issues that prevent Siri from reaching Apple’s servers.
7. Check microphone hardware. Open the Voice Memos app and record a short clip. Play it back to confirm your microphone is working. If the recording is silent or distorted, the microphone may be blocked by a case, debris, or hardware damage.

How to Fix Siri Not Working on Mac

Siri issues on Mac follow a similar troubleshooting path. The steps below address the most common problems.

1. Check your internet connection. Open Safari and load any website to verify connectivity.
2. Confirm Siri is enabled. Open System Settings and click Siri. Make sure Ask Siri is turned on.
3. Restart your Mac. Click the Apple menu and select Restart. A fresh boot clears background processes that might block Siri.
4. Update macOS. Open System Settings, click General, then Software Update. Install any available updates.
5. Check microphone permissions. Open System Settings, click Privacy & Security, then Microphone. Make sure Siri has permission to use the microphone. If you use an external microphone, verify it’s selected as the input device under Sound settings.
6. Reset Siri by toggling Ask Siri off and on. Wait 20 seconds between toggling off and on, then retrain “Hey Siri.”

If none of these steps work, try creating a new user account on your Mac and testing Siri there. If Siri works on the new account, the issue is specific to your user profile rather than a system-wide problem. In that case, deleting Siri’s cache files from your Library folder may help. Navigate to ~/Library/Caches/com.apple.assistant* and move those files to the Trash, then restart.

How to Fix Siri Not Working on iPad

iPad troubleshooting is almost identical to iPhone. The same Settings paths and toggles apply. One iPad-specific issue to check: if you use an iPad with a Smart Keyboard or Magic Keyboard, make sure the keyboard isn’t intercepting the button press meant to activate Siri.

On iPads without a Home button, press and hold the Top button to activate Siri. On iPads with a Home button, press and hold the Home button. If neither works after trying the steps in the iPhone troubleshooting section, perform a forced restart by pressing and quickly releasing Volume Up, then pressing and quickly releasing Volume Down, then pressing and holding the Top button until the Apple logo appears.

Frequently Asked Questions

Does resetting Siri delete my personal data?

Toggling Siri off and on does not delete your contacts, messages, photos, or any other personal data. It only resets Siri’s active session and voice recognition model. Deleting Siri & Dictation History removes voice interaction data from Apple’s servers, but this is separate from any data stored locally on your device.

Will I lose my Siri Shortcuts if I reset Siri?

No. Siri Shortcuts are stored in the Shortcuts app and are tied to your iCloud account. Toggling Siri off and on or deleting Siri history does not affect your saved shortcuts. They will remain available and continue to work after you re-enable Siri.

How often should I retrain Hey Siri?

There’s no need to retrain on a schedule. Only retrain when Siri stops recognizing your voice reliably, when you move to a new environment with different background noise, or after a major iOS update if voice recognition seems less accurate. For most people, the initial training lasts years without any issues.

Can I use Siri in two languages at the same time?

Starting with iOS 16, Siri supports multilingual speech recognition. You can speak to Siri in two languages without switching settings, as long as both languages are supported. Go to Settings, tap Siri, then Language, and add a second language if the option is available for your language pair. Not all language combinations are supported.

Why does Siri keep activating when I don’t say anything?

False activations happen when Siri’s voice model picks up sounds that resemble the wake phrase. Retraining “Hey Siri” in a quiet room often reduces false triggers. You can also switch from “Hey Siri” to pressing the Side Button only if false activations are a persistent issue. Go to Settings, tap Siri, and turn off Listen for “Hey Siri” while keeping the button shortcut enabled.

Does deleting Siri history affect Siri’s accuracy?

In the short term, slightly. Apple uses anonymized voice data to improve Siri’s ability to understand your speech patterns. After deleting the history, Siri rebuilds its understanding based on new interactions. Most users don’t notice any difference in daily use. The on-device processing capabilities added in recent iOS versions mean Siri relies less on server-side data than it used to.
