Seiyuu Explained: A Beginner's Guide to Anime Voice Acting

"Seiyuu" is the Japanese word for voice actors. In anime, the voice performance carries a large share of a character's personality, so it is worth knowing how the work is done. This guide covers the basics without needing any industry knowledge.

How voice casting works

Casting usually involves the director and sound director listening to audition recordings and choosing the voice that fits the character's age, temperament and role. A single actor can play several small parts in one series, and well-known actors sometimes voice characters of very different styles.

How recording sessions usually run

Voices are typically recorded after the animation is at least roughly complete, working from a rough video, so actors match their timing to the mouth movements on screen. Cast members often record in small groups rather than all at once. Because of this, the final performance is shaped by direction as much as by the actor.

What to listen for

• Range: how the voice changes between calm, angry and emotional scenes.
• Breathing and pauses: small details that make dialogue sound natural.
• Consistency: whether a character sounds like the same person across a long series.
• Fit: whether the voice matches how the character is drawn and written.

Subtitled or dubbed?

Both formats employ trained actors. Subtitles let you hear the original performance, while a dub lets you watch the picture without reading. Our sub vs dub comparison lays out the trade-offs so you can choose by situation instead of by habit.

Building your own list

If you notice a voice you like, note the series name and the character in your watchlist. Over time you will recognise actors across shows, which is a pleasant way to discover new series. Always check the credits of the official release, since casting details can differ between the original and each dubbed language.
