One of the things I really would like to try doing is to apply patches to Emacspeak to fix Unicode support and add Multispeech support so russian users could use the latest Emacspeak with latest Emacs with russian support. However, I don't have any knowledge of lisp. I think if AI could help me in applying git patches but I am not sure about it. Maybe it is worth trying because if something happens to russian Emacspeak version developer, nobody takes over that.
