Traveling Through the Western Fantasy, but Becoming Mute and Unable to Recite a Spell?

Being summoned to a Western fantasy world where everyone has the possibility to become a magician, but because he was born mute and unable to chant spells, he missed the path to magic? Fortunately, my talent for magic is unprecedented, and I have a parchment that keeps talking and reciting spells for me. Wait, why are the magic spells not the characters of the Western fantasy world, but Chinese characters? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
