On Android 7, with the "Phone" app in the settings you can select an option that allowed you to take a voice call by saying "answer"
You could also end a call by saying "hang up"
Since Android eight, this system is no longer installed. I would therefore like to be able from a small application, if it would be possible thanks to a voice system to be able to press the answer button by saying "pick up" and then press the hang-up button by saying "hang up"
Is it possible ?
