I've just reinstalled Autovoice on a new phone after a little while not using it so I am a little rusty and had to get up to speed with newer integrations and obviously Google have changed Google Now to the Assistant since I last did this. Anyway I found the option in Autovoice to 'Replace Google Assistant' in the hope that saying "OK Google" will trigger Autovoice. However I still get Google coming up. However, I do get Autovoice when I long press the home button though. Running Android 7.0 on a Samsung S7. I'm aware of the warning this "may reset on reboot in Android under 8.0", but haven't rebooted and checked the default assistant app is still Autovoice. I just can't get it to start via voice. FWIW .... I hoped for a solution here because I choose not to switch on all my web and location history on Google, and I'm disappointed Google are now forcing me to do this to use Assistant. Google Now used to do fine without these, and I still can launch the "old" Google voice commands from a home screen and it responds as expected with these swtiched off, but as soon as I'm on any other screen "OK Google" brings up the new Assistant, which I have disabled. I'd be satisfied if I can force this to use the "old" Google (which must still be on my phone as it triggers from the home screen), or failing that just bypass it straight to Autovoice and I'll create my own darned Assistant!
