Siri not working through Bluetooth in iOS 13

For what it's worth my issue was resolved by hard resetting my iPhone. Holding the home and power buttons down until the phone turns off. then let the phone turn on again. I don't know that this will help you, but perhaps someone else looking at this thread will benefit from it.

I'm having exactly the same issue with iPhone 11 pro. In the car I can say "Hey Siri" and i will register my request and do whatever I ask it to do but the siri voice is not being played. You can tell the Bluetooth unit is engaging but I can't hear siri responding. If I ask it to play music it will do so but it will not speak out the words. Same if I ask it for the weather info, it will display it on the screen but no voice over bluetooth. This issue occurs only over bluetooth. On it's own it works as it should. It's driving me crazy!

Apple seems to be pretending this issue is not there, it has remained in a few updates now

Ugh! This has been driving me crazy! Apple please fix! Thank you to all of you for posting- I thought I was going to go crazy trying to fix this, but it’s not for me to fix, I guess.

Yes fixed now, seems a bit slower to start to get a response but it is working again

Same issue here not using headphone though. I'm using the built in Bluetooth on a 2017 Subaru and a 2017 Chevy. Both have been working just fine with this phone for 2 years. Now after iOS13 I get responses from Siri like "I'm on it" or "just a second" but she always fails. Like mm0058 says it works fine when I press the button on my phone and issue the same command.

iPhone 6s, iOS 13.1.2

The hard reboot worked for now. Since I upgraded when connected to Bluetooth Siri would not give voice feedback. The act would be completed but no feedback over the speaker. I have been working with Apple off and on for months and zero help. Truly, thank you for posting this it has been driving me nuts

Me too! Very frustrating. I had my car for 6 years now and never had any Siri issues when my iPhone was connected via Bluetooth, now since iOS 13, Siri responds but I can’t hear anything at all. Bluetooth audio however works just fine.

I thing fixes it, I even bought and returned 2 iPhone 11 Pro maxes now! Deleted pairing in car, retried, reset iPhone, hard reset, you name it. The absolute only way to hear Siri respond back is to completely delete the phone from the cars audio system, then the Siri audio comes out of the phone itself. Even if plugged into the cars stereo via USB/lightning, no Siri voice can be heard anymore. APPLE PLEASE FIX!!!!!

I'm having the same problem with Siri "working on it" ever since an update. Siri stopped playing welll with my ISOTunes bluetooth headset. Came to this page, did the reset somebody suggested and Siri worked, making the call I asked. Then I asked her to text somebody. "Just a moment". "Working on it". "Sorry, I'm having trouble with the connection".

I'm 10 feet away from the WiFi antenna and I've got 2 bars on the cell service (which I all you ever get out here).

And now...it's working again. Just double checking after typing the above. I didn't do anything else. And now it quit. It sent a text, answered a text and then Siri started with the "working on it" again. ???

iOS 13.3.1 beta fixes it (mostly), but now sound is very choppy. Very bad stuttering of both Siri talking and talking to people on the phone via Bluetooth. Siri DOES now reply back to you over Bluetooth or via direct USB connection to your car stereo. Apple just now needs to fix the bad stuttering / voice quality of Siri and phone calling when connected to car.

Yes... sort of. I installed the iOS 13.3.1 beta update and it now works as expected. If you want to do this just google enrol IOS beta update and you should be able to find it. You will need to enrol and follow the instructions to install it. Pretty easy. Once they come up with the official update I will un-enroll from the program.

iOS 13.3.1 beta 2 mostly fixes it. Wait fir the iOS 13.3 update to be released and it should help. Although audio call quality over Bluetooth is still a bit choppy, but better than it was in iOS 13.3.1 beta 1

My issue is a bit different, on my car sound system "hey Siri" works but Siri voice is muted and you cannot hear what Siri is saying?

Thanks, that was the first thing I tried, also deleted the pairings and reconnected them still no joy
