I tried it out. However, i noticed there may be some grammars in English version, not saying it's a bad thing or anything. I can understand since i assume English isn't your native language. 😅
Another thing to mention, when i muted the voice, Charlie and Charles somehow still managed to speak a dialogue using their voices despite the settings having it turned off so...i wonder if this was a bug because it caught me off guard lol. 😭
