Example doesn't work on Samsung Galaxy S7 SM-G930F

[cristianrablau]

Hello,

The example provided here doesn't work on my Samsung Galaxy S7 SM-G930F(Android 8.0.0). When I press the Start button and speak there is no recognized word or error shown.

I suppose the example should work on my device, so do you have any idea how could I find the source of the problem?

Update: I was able to test the same app on a Samsung Galaxy A5 2016 SM-A510F(Android 7.0) and the recognition works on that device.

[sowens-csd]

Yes, it should definitely work on that device. Is there any log output with more information?

[cristianrablau]

There was nothing that I noticed. I will post an entire log soon.

[cristianrablau]

I can see E/SpeechRecognizer(23441): bind to recognition service failed in the logs.

[cristianrablau]

It could come from here(not sure this is the latest version of the code): https://android.googlesource.com/platform/frameworks/base.git/+/79896bd123aa3bc69c6455d4e2ddf2b2b555e6e5/core/java/android/speech/RecognitionManager.java

[cristianrablau]

@sowens-csd Do you think this is coming from the package? Or can it be fixed in the package?

https://github.com/flutter/flutter/issues/34411#issuecomment-590307834

[sowens-csd]

Thanks for this report, this is really helpful. I'm going to do some research into that bind method and see what could cause failure. This at least helps localize the problem for me, thank you.

[sowens-csd]

Some interesting content out there on this issue.

There are some SO threads that suggests a change to the Google Speech settings: https://stackoverflow.com/questions/37607246/speechrecognizer-is-not-working-if-enhanced-google-services-is-selected https://stackoverflow.com/questions/31986689/bind-to-recognition-service-failed, see the picture here https://i.stack.imgur.com/d1bDO.png

[sowens-csd]

I just committed some changes that may help. There are two main approaches in this commit. The first is that the code now checks if a speech recognizer is available on the device before completing initialize. If it is not then initialization will fail with an exception. The second is that more sections of the initialization are done on the main UI thread. Some of the documentation suggests that various parts of the speech recognizer should be created on the main thread.

If you could try this version from the repo and let me know what happens that would be very helpful. I'd like the log output if it doesn't work.

[sowens-csd]

1.0.0 is now on pub.dev with this fix. Let me know if it helps.

[cristianrablau]

I will try the new version soon.

[cristianrablau]

Hi @sowens-csd, thank you for all the support! Now I can see on the screen 'Speech recognition unavailable'. I will continue the investigation to see if I can find and change the SpeechRecognizer provider on my phone.

I managed to activate a speech recognition provider. Here are the steps:

1. Go to Google Play
2. Search for 'Google'
3. You should find this app: https://play.google.com/store/apps/details?id=com.google.android.googlequicksearchbox
4. Mine was 'Disabled' so I enabled it

@sowens-csd Do you have any idea about the new error? Could it be something with my phone?

[sowens-csd]

Sorry, I missed this follow up question. Given what you had to do to enable the recognizer I'm wondering if this could be related? https://stackoverflow.com/questions/46376193/android-speechrecognizer-audio-recording-error

Can you check the suggested fix on that thread and let me know if it helps?

[cristianrablau]

The suggested fix worked. Thanks a lot for all the help! Now that we finally resolved all the problems I think these steps could be added in the documentation somewhere 😄 (it might help others as well)

[sowens-csd]

That's great news. Sorry it took so long to get there, but very happy we've resolved it. I agree that this information could be really useful. I'll add an overview to the Readme and include a link to this thread as well. Thank you for your patience and help in diagnosing the issue. It's this kind of detail work that makes plugins better. I'll leave this open until I've updated the docs.

[cristianrablau]

No problem @sowens-csd , keep it open as long as needed. Glad I could help!

[sowens-csd]

Documentation issue resolved in the latest Readme.

Hi how did you install the app? I'm with a galaxy watch 4 classic and can't install the google App

[kusmayadi2022]

i have problem E/SpeechToTextPlugin( 3646): Speech recognition not available on this device E/flutter ( 3646): [ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: PlatformException(recognizerNotAvailable, Speech recognition not available on this device, , null).. I've built a voice-driven android app that uses the android speech recognition API. I'm currently trying to convert the app to a wear-os version. I've included the speech recognition permission in the apps manifest and have initialized the speech recognition instance the same as I have in the mobile app (which works!). The app launches well, however when I begin the speech recognition I get the following error: E/SpeechRecognizer: no selected voice recognition service

I've tested on both a physical Galaxy 4 watch, and an API 30 wear-os emulator and the problem occurs with both devices. I've installed google assistant on the devices, and google assistants voice recognition works well. I can't find and voice input / speech recognition settings on the app. I'm not sure what next steps to take in debugging this.

I want voice recognition to be detected so that it can be used on Wearos
