3 months ago Sorry for the late reply but are you sure that this is not a problem with the microphone or the package you are using for the recording?
Which package are you using to record the audio?
Describe the bug I have integrated the google_speech package correctly, and it works fine on Android. However, when I run the iOS app and click on the mic button to start transcription, the app crashes immediately with the following error in Xcode:
Terminating app due to uncaught exception 'com.apple.coreaudio.avfaudio', reason: 'required condition is false: IsFormatSampleRateAndChannelCountValid(format)' First throw call stack: (0x199628f20 0x1914e2018 0x19972766c 0x1b31a0198 0x1b3202714 0x1b327c08c 0x1021ed37c 0x1021edc7c 0x1021eaac4 0x1021eb110 0x105521630 0x104f7d644 0x1022fcb98 0x1022fe7bc 0x10230ed58 0x10230e90c 0x1995fb710 0x1995f8914 0x1995f7cd8 0x1de4a81a8 0x19bc3090c 0x19bce49d0 0x100d9c918 0x1bcca9e4c) libc++abi: terminating due to uncaught exception of type NSException AVAEInternal.h:76 required condition is false: [AVAEGraphNode.mm:832:CreateRecordingTap: (IsFormatSampleRateAndChannelCountValid(format))]
I have tried different sample rates (16000, 44100, etc.), but none of them worked. The issue persists on a real device (iPhone SE 2020).
To Reproduce Steps to reproduce the behavior:
1 ) Integrate the google_speech package in a Flutter app. 2 ) Configure the sample rate and other necessary settings. 3 ) Run the app on an iOS device. 4 ) Click on the mic button to start transcription. 5 ) Observe the app crash and the error in Xcode.
Expected behavior The app should start the transcription process without crashing.

Additional context The issue does not occur on Android; it works fine on Android devices. The problem is specific to iOS.
