Siri not responding on iPhone 16 Pro Max

My issue was fixed with the new iOS 18.0.1 software update

This worked… hopefully it will stay

every iPhone from 3GS and I’m really thinking about leaving however I have an ultra 2 iPad 13 pro iMac home hub MacBook iPad mini and the OS on them all compared to an S25 ultra with Gemini AI seems 10 years behind as for the Siri issue

1. Go to Settings > Siri (or Apple Intelligence & Siri).
2. Tap Talk to Siri, then tap Off.
3. Turn on “Siri” or “Hey Siri” again, then follow the onscreen instructions.

Every suggestion here works temporarily. That is the problem, nothing works consistently. It is a bug and needs to be fixed by Apple.

All of the fixes are only temporary, and the fact that multiple people are trying multiple "fixes" is just further proof that this is a bug Apple needs to fix. Pretty please, Apple!!

I’m having the exact same issue

I am having the same problem as well works fine for a little while if I power down and back up the phone but eventually stopped working

Same with mine. Only does it when AI features are turned on. As soon as. I turn off AI & Chat GBT features Siri works like normal. It’s annoying!

mine already set to this.

has worked fine since purchase and now today it’s failed every time.

I’ve come from a 13 pro max that worked perfectly for 2 years and use 50 times a day making phone calls on the road.

this is so frustrating.

I have a similar issue on iPhone 14PM. iOS 18.

I can see Siri active and listening to me when I ask it to say dial a number, but then nothing is executed. And, I'm not going to lie, having to perform several different types of "fixes" is ridiculous at this stage in the phone game.

Hi Everyone - I have the iphone 16 pro max and was having the same issue. I had to do the similar trouble shooting checking off 'hey siri' from the settings>siri>talk to siri but also disabling 'press side button for siri'

Now its working. Hopefully there's an update soon

I tried these all. Still not fixed, if I restart it fixes it for the moment then it happens again. When I went and turned off hey siri then on again, pop up for set up came and now it doesn’t recognize my voice or respond at all even to complete the setup!

I went to settings>siri and tried everything suggested. Didn’t fix the problem. But when I went to settings> accessibility> Siri (at the bottom under “general”) and turned on “always listen for Siri” it fixed it. I also turned on “listen for atypical speech”. Sometimes I mumble so i figured it ight help to have on too. Hope this helps someone

So I’m one of the ones that posted that Siri wasn’t working on my 16 Pro Max. So I finally decided to go into the settings for Siri. There is a setting that says “talk to Siri”. When I hit that, it showed that Siri was turned off. As soon as I turned it on to “ Siri or hey Siri”, it works just fine now. So everyone should go check their settings.

Siri worked just fine for my iPhone 13 Pro Max. If the settings were supposed to be the same when I switched from that to the 16, I don’t understand why Siri was not left on.

I just upgraded to the 16 Pro Max a week ago and my Siri has working just fine up until today. It will work when I say hey Siri, but it would only work when I use the side button I went under settings to accessibility and then to voice commands, and that was turned off, I turned the voice commands on, and it is working perfectly since, You may want to try that :)
