Hi, I face an issue with AVSpeechSynthesizer after iOS 16.

I got many crash reports from my clients, but unfortunately, I can't reproduce this on my test devices. Does anybody face this also?

I think the AVSpeechSynthesizer has a big memory problem, I see the same crashes -> See following thread https://developer.apple.com/forums/thread/713848. Please add tickets in http://feedbackassistant.apple.com and refer to my ticket number FB11401700 to let Apple know that many Apps have this problem. I reported it long ago, but still no fix in an IOS update.

the same crash.

It happens on all iOS 16 devices. It happens easily if you play and stop it repeatedly. When playing, it seems that the error does not occur if AVSpeechSynthesizer is finely separated by spaces and played back. Errors do occur, but they may occur less frequently. I tested it with an app that plays TTS in that way, but the app didn't die.

There are several symptoms when an error occurs. It can't stop playback, loses control, and continues to play until the end of a sentence. If an alarm or call comes in while TTS is playing, the phenomenon of listening through the earphones and playing back through the speaker also occurs.

I temporarily took measures to prevent the above problem from happening without the app dying. A quick iOS update should fix this problem.

Unfortunately it hasn't been fixed for the iOS 16.1 release, now I'm seeing a lot of crashes due to this problem.

As a result of checking, an error occurs when playing TTS for more than 1 hour. My app repeats long sentences infinitely.
