Is there a way to use your voice to open apps in Android? Is there a way to use your voice to open an app in Android?

I would like to say the exact phrase, "Run GMail" and it starts the gmail app.
Yes, there is. At least for some app names it should work fine. You should start a voice search with the "Google App" and press the microphone button in it to speak and say "open application". I've tested trying to open a couple programs: 


open gmail
open telegram
abrir caixa (Portuguese for open and a bank app...)
open just java


All of those worked and it is not limited to English. If you have a phone like a Samsung Galaxy, I think there is another app that lets you voice control, but I am not sure if it is worse/better than the Google App.
