Siri not responding on iPhone 16 Pro Max

My issue was fixed with the new iOS 18.0.1 software update

I had similar issues until I rebooted the phone.

I tried turning Hey Siri off/on, retraining, switching from “Hey Siri” only to “Siri or Hey Siri”; all without any luck. On a whim, I powered off the phone and tried again once it came back up. Things are now working as expected.

This worked… hopefully it will stay

If it were only as simple as that. For (almost) all of us, we have already been using Siri, so that setting is already turned on. Siri just stops responding after a while. And, only have one or a couple of reboots does Siri start working again.

iOS 18.x has been the buggiest software release yet because Apple is presumably devoting so many resources to Apple Intelligence, trying to play catch up when in actuality Apple Intelligence has been almost completely useless to most people. Apple needs to focus on the basics first and then worry about "extensions". They need to force employees to stop working from home and come back to the office because they are obviously not working and/or communicating with each other. These bugs are not "rare" or "unusual" bugs. This thread has 1600+ "me too", and that is for people who are frustrated enough and tech savvy enough to find this support thread.

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
