duplicate of https://github.com/Picovoice/picovoice/issues/82

creating duplicate issues won't accelerate resolution and simply delays it by creating extra admin work.

FadiChaalab commented 3 years ago

I recreated the issue because i used porcupine flutter package and forgot to close it in the other one. Forgive me for my mistake but could you reopened again, i really need help on this issue.

FadiChaalab commented 3 years ago

This is my main page:

main dart - background_voice - Visual Studio Code 5_21_2021 6_43_29 PM

And speech_service.dart file has the initialize method for porcupineManager and all the logic that i need to fire get location and record sample of audio when the wake word detected. Everything work fine in foreground but when i try to run it in background service it fails with the error above. It seems that it fails because it can't determine if the app hasRecordAudioPermission in background.

@FadiChaalab we've never claimed or attempted Porcupine Flutter on a background service. There is definitely some complications around running the cross-platform audio recorder outside the app. This is definitely a valid use-case that we'd like to support, but I can't promise we'll add this capability right away. We'll keep the issue open and hopefully someone can help you out in the meantime.

Would this be why I can't get the flutter example on iOS to work with wake word when the app is not in the foreground?

Hi @kenarsa this issue was closed as completed, is there a background listener available for flutter, I don't seem to see anything? Similar to @FadiChaalab commented I get MissingPluginException(No implementation found for method listen on channel flutter_voice_processor_error_events) if I run it in Flutter Background Service Thank you in advance for any assistance.

EDIT: I got this working, the trick was to call the _porcupineManager start from within the initState in _MyAppState

kenarsa commented 2 years ago

@olivermoo that was my mistake. I closed the issue as not planned. We do have background recording for native Android and iOS but never claimed nor planned to add it to cross-platform mobile SDKs. If contributors what to add this based on our native SDKs we are very much open to PRs. Sorry about the confusion.

Has there been any development on this feature since?
