Hey laima146,
If we understand correctly, Siri is not working on the iPhone or the Apple Watch. It looks like you have already done some troubleshooting to solve this issue. Even though there is a chance that you've tried these steps already, we would recommend you follow every step and let us know if the issue persists.
- By default, Siri won't respond when your device is face down or covered unless you go to Settings > Accessibility > Siri and turn on Always Listen for "Hey Siri."
- If Lower Power Mode is turned on for your iPhone, you can't use "Hey Siri.""
If "Hey Siri" isn't working on your iPhone or iPad
"After each step, see if Siri responds:
- Check the Internet connection on your Apple Watch.
- On your iPhone, see if Siri is turned on. Tap Settings > Siri & Search, then turn on Listen for "Hey Siri". On iPhone X, turn on Press Side Button for Siri. On iPhone 8 or earlier, turn on Press Home for Siri. Your Apple Watch mirrors your iPhone, so you don’t need to check your watch.
- On your Apple Watch, see if Hey Siri is turned on. Tap Settings > Siri.
- Restart your Apple Watch.
- On your iPhone, go to Settings > Siri & Search and turn off Listen for "Hey Siri." Then turn it on again.
- See if the microphone or speaker on your Apple Watch is blocked. For example, if your device has a protective case, remove it.
- If Siri doesn't speak on Apple Watch Series 3 or later, you might need to download its voice. The download happens when you’re on Wi-Fi and your Apple Watch is charging. To give the download time to complete, try charging your Apple Watch overnight. To check the status of the download on your Apple Watch, tap Settings > Siri, then scroll to Siri Voice. Learn which languages Siri speaks.
If Siri still doesn't respond, contact Apple Support."
