AutoVoice Autovoice don't listen ok google

Its about a month that autovoice don't trigger by ok google command when offline.And when online sometimes works and most times a toast popup with message "searching......". I am on android pie custom rom.

 

Let me explained better. Until some time before when i say ok google if i was tell a command at English autovoice made tasker to execute a task. This part worked online and offline as well. And if i say a command at Greek that is my System language I can do simple things like to learn about weather for example this this worked only online. this is normal but now when offline AutoVoice do nothing just a Post pop up that say "searching....", Nothing else
