How to send voice command to Android device via ADB

Issue

I want to invest to test command my application through voice command something like "OK GOOGLE". In addition to the method of using speakers to speak loudly, how can I say "OK Google" through ADB?

Thanks a lot

Solution

I was using Audio Loopback Dongle for call simulation. Hope it will works for commands too

wav generated by sudo apt-get install libttspico-utils

pico2wave -w google.wav "OK Google"

Move to device

adb push google.wav /sdcard/Download/

Playing wav by VLC:

adb shell am start -n org.videolan.vlc/.StartActivity -a android.intent.action.VIEW -d file:///sdcard/Download/google.wav -t 'audio/wav'
