Seiyuu (Japanese Hiragana: せぃゆぅ), the voice actor is different from the actor. He can hide behind the scenes and not show up. He wants the voice effect. Japanese seiyuu organizations mostly cooperate with film and television departments, advertising companies and government media, mostly non-governmental organizations.

Seiyuu is the title of "main voice", which is equivalent to "voice actor" in Japan. "You" means "actor" and "performer" in ancient Chinese and Japanese. Seiyuu is a person who performs with voice, which means "voice actor" in Chinese. Romaji is the voice actor, and the English name is VA (voice actor). Many people mistakenly think that CV (Character Voice) is short for Japanese seiyuu, and some even think that CAST is seiyuu. In fact, CV is only used to indicate which dubbing actor is dubbing the role in the work, that is, the meaning of dubbing the role is not the name of seiyuu, and CAST is the meaning of the cast list, which has nothing to do with seiyuu.
