I don't really understand why you would put an English voice on a Japanese Vtuber. This isn't like an anime, where there is likely an English Dub. You would've been better off just putting duck quacks in this as the "voice". Better yet, just use Subaru's actual duck sounds as a Simlish or Link Grunt type of pseudo speech.
