Trying to make AI-Stallone voice to say what I wanted it to say was a nightmare sometimes.
In many cases I needed to find different words of the same meaning cause it failed every time to say what it was supposed to say. Sometimes I needed to figure out what should I write to get the result I needed cause the voice read something wrong. For example - if I wanted it to say “bear” I needed to write “baer”, because it reads “Bear” as “Beer” (as can be heard in the trailer).
Also, sometimes it reads the words differently in complete sentence compared to stand-alone words, and stand alone may sounded better or worse, so there was a need to record words separately and edit the sentence from them.
