Flutter SpeechToText doesn't work on Android

[DevDJpl]

I have all the permissions added, it doesn't show me any errors when compiling in Android Studio, but it doesn't work completely SpeechToText both in the mobile emulator and on the physical device only works on the web emulator.

Permissions: <uses-permission android:name="android.permission.INTERNET"/> <uses-permission android:name="android.permission.RECORD_AUDIO"/> <uses-permission android:name="android.permission.BLUETOOTH"/> <uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/> <uses-permission android:name="android.permission.BLUETOOTH_CONNECT"/>

And I'm a beginner with Android and I have no idea what's wrong and I've been looking for a solution for several days. I need this to work because I'm writing my own voice assistant

[sowens-csd]

Is the example app working on the physical device? Have you checked the README notes for ensuring the voice assistant is properly installed on the Android device? What is the model and version of the Android device?

[sowens-csd]

Any updates on this?

[DevDJpl]

I checked on a virtual device and on the phone. It doesn't work on both virtual and phone. The Google Assistant works normally on the phone and SpeachToText did not work on the device. I checked it on the browser where everything worked normally.

[DevDJpl]

On any device doesn't work. We use Android version on app 8+

[sowens-csd]

Have you tried the example app on the same device?

[DevDJpl]

Yes I tried

[dnfatec]

I have same problem in Android 8.1, but in recentily version, no problems!

[sowens-csd]

It could be a problem with an older version of Android. I only have test devices for 10, 11 and 13, all of which work. The minSDK is set to 21 but it's possible I introduced an incompatibility with older versions. Can you confirm what version of Android you are using and whether it works on newer versions?

[dnfatec]

Hello!

I did new tests, with old versions (Android 8 and Android 8.1) in other smartphones and no have problems. Today, i did new configurations, this smartphone

[image: image.png]

Google permissions to microphone no did active. But after active, the capture voice in the app normalized

Thanks

I tested on Sony Xperia and not works

[sowens-csd]

If you're still having problems can you post a log from a phone that isn't working. Make sure to use the debugLogging: true setting in the initialize method before you do the capture.

[DevDJpl]

And how to do it? Because I only know how to do it in Android Studio

The app in speech-to-text/speech-to-text/example works. That's a nested folder with the same name.
