AutoVoice "ok google" work only with text, but not with voice

Hello. Strange things going on with autovoice. All this time everything worked well, but now I can't say "ok google ask autovoice" and get respond "Sure Lets get autovoice". When I type in google assistant "ask autovoice" all work fine, but not with voice. With voice I get a message "I'm really sorry about this, but autovoice isn't available on devices set up for your language or country" I don't know what happened. Settings did not change. Language and country set USA. Please help me.
