I just bought this package.
And I tested this package on S8.
But it gives nothing option in “select detection language” dropbox of “SetLanguage” scene.
Also, it gives me “Sorry, but this device doesn’t support speech recognition” message in ExampleScene” scene.
Please refund my money or resolve this issue within one day.
It seems you disabled Google app on your device which disables Speech Recognition engine as well.
Some more info here:
I ended up going into PlayStore and looking for “Ok google” and I found that Google LLC was disabled. I enabled it and Speech Recognizer started to work again.
On Samsung S9 one can disable the Google application, and that will in turn disable the STT service. Found out the hard way.
