Does я become и when unstressed just like in russian?
I think so. Native Ukrainian speaker here
Silent Д!? and I couldn't hear Я as Я...
You say it like chortinatsat, and the Я is there, but not very stressed. Not 100% sure, but it will get you by in any conversation.
Я-українець і не можу пройти "чотирнадцять"!В програмі брак на цюму місці,виправте!
