Alas, my enthusiasm was a little bit premature. While my iPhone running iOS 26 proves that the problem has been fixed, somebody's iPad (though running at the moment iPadOS 18), despite getting the app being compiled and installed from Xcode 26, shows the bug being still there. How come that iOS 26 does have a fix, but iPadOS 26 does not (I checked on Simulater as well).

Finally, there's a good news: in iOS 26 RC the problem - Speech Recognition in custom implementation - appears to be fixed! No more disappearing of the transcribed text after a pause. At least in my tests/trials of this functionality, it works as it did before upgrading to iOS 18. Thank you, Apple!

A slim hope. Somebody on the Internet has claimed that the bug is recognized by Apple internally. https://forums.getdrafts.com/t/ios-18-macos-15-beta-warning-for-dictation-users/15334

@righteoustales No reply for me either. Apparently, this bug has low priority. Nevertheless, it would be a matter of curtesy if not respect on the part of Apple toward developers (respect, by the way, they swear on all the time) to at least drop a line informing that the report(s) are on the backlog and will be looked at when the time permits.

@DTS Engineer I've read you post about the rules of Feedback Assistant. Thank you for clarifying certain points. Nevertheless, I can't help asking a question: if "Feedback Assistant only shows you bugs that you filed", then what the purpose of the header of the page: "Recent Similar Reports:None Resolution:Open"

@DTS Engineer I did receive a request from Apple to clarify the framework(s): "Apple Sep 26, 2024 at 1:53 PM Engineering has requested the following information regarding your report: Is this with mainstream Dictation or Voice Control?" Sure enough I clarified that it's Dictation and the frameworks I used are SFSpeechRecognizer, SFSpeechAudioBufferRecognitionRequest, etc. As you can see it was a week ago, and so far I haven't heard from them. What surprises me is that I don't see other reports on that bug. All of the numbers except mine - FB15245186 - return 'Not found'. Needless to say that if I get any response, I'll post it here.

@DTS Engineer Another # FB15245186 though it's even more recent then the previous ones.

@Squids "I’ve reached out to Apple" Me too :), but so far no response.

@34534543456789098767654 No, I haven't found a solution to the problem - intermittent truncation of transcribed dictation. So, I reverted to Apple standard way - using its keyboard dictation functionality, which works as expected. By the way, for some unclear reason(s) after a few instances, the error messages that I mentioned in initial post stopped appearing.

One more attempt to get an answer, or at least a cofirmation that the problem does exist. If somebody willing to spend just couple of minutes to run Apple own demo app 'SpokenWord' - https://developer.apple.com/documentation/speech/recognizing_speech_in_live_audio?language=objc - under iOS 18.0 Here's what I ask: start dictation and make a natural pause - say, 1-2 seconds. What you are going to see is that the previously transcribed text is completely truncated and the transcription starts anew. Once again: it's Apple own demo app

The follow-up to the previous post. It looks likes during dictation if I make even a short break - 1-2 seconds, the previously transcribed words disappear and the transcription starts anew. Let me reiterate, that does NOT happen under iOS 17. The app downloaded from the store functions as expected. Yet the very same code compiled under iOS 18 shows the problem: even a 2-second pause in talking truncates the previously transcribed text and starts anew. The quickest and simplest test is to run Apple demo app 'Spoken Word' Any insights would be greatly appreciated.

Well, I gave it a try and it did work! The app in Simulator did run. Thank you for the 'patch', though it would be nice to get a real fix.
