You’ve already shown a flaw, which is that English inflections do not match other languages. “I will go” in English is not “Je irai” in French but rather some more like “moi, j’irai.” The sound of the voice also wouldn’t make any sense because different dubs will change to fit local stereotypes. In the states they will have someone sound like a redneck but in Germany they might lean into a Bavarian accent for the same effect.

With the low level of understanding demonstrated in your comment, plus the high level of confidence in your solution, you’re showing exactly why it’s a bad idea. Just pay voice actors and pay them enough that they will actually be of a certain quality instead of bitching that the dime-store VA people aren’t giving you top-tier performances.

Take the AI and throw it straight in the garbage. We don’t need it and we don’t fucking want it. All it does is cost more money to produce a product that only an ignorant, over-confident corpo thinks is any good.
