For japan you have vocaloid. They took samples from some "ideal" singing voices and made a virtual libraries. It sounds odd in English.
Speak2go ( Mini-speech software ) is a speak and type-it. You also have Balabolka which is similar. They have tons of voice types meant for reading books, but you could speed them up or slow them down . Like Microsoft sound or Apple did this a long time ago. You could possibly find voices for those and then edit them in a sound-editor like Fruity-Loops or Audacity ???
Honestly do not make fun of Eastern Europe. People are shocked and horrified about the whole thing. For many peoples lives it has turned peoples views upside down. Honestly it looks more like Putin is a puppet of some sort because that was not his stance before COVID.
I blame the virus, China, and of course Zionist Israel for wasting our lives.
