Starfire voice actors and versions: animation, film and live action
A continuity-first reference for the performers and screen versions most often associated with Starfire.
Scope: Official DC and Warner Bros. Discovery programme pages
Quick answer
Hynden Walch is part of the principal cast named for Teen Titans Go!, while Anna Diop portrays Kory Anders in Titans. Voice and live-action credits are version-specific, so a single answer without the title can mislead.

Animation credits need a title
DC’s Teen Titans Go! page says that the series brings back Robin, Starfire, Raven, Beast Boy and Cyborg for new comedic adventures. It lists Hynden Walch among the returning principal voice cast. That makes her the relevant official credit when the question specifically means that television production.
The page also makes clear why a title matters: Teen Titans Go! is a comedy-led series with its own setup, even while it returns the familiar team. A broad “Starfire voice actor” answer without the production name can accidentally answer a different animation, a film, a game, a dubbed release or a live-action series.
Live action is not a voice credit
DC’s Titans page lists Anna Diop in the cast and presents Starfire as part of that live-action team. That is an on-screen performer credit, not a substitute for an animated-voice credit. It belongs on the same reference page because users compare versions, but it should be described in the correct form.
DC’s page for Teen Titans: The Judas Contract lists a separate film cast. Where an official page lists a cast but does not visibly map every character to every performer in the public summary, this site links the official production page instead of guessing from third-party cast lists.
How to find the correct credit
Start with the production name and medium. For an animated series, check that series’ official page; for a film, check the film page; for a game, check the publisher’s game credits; and for dubbed versions, use the relevant regional release. This avoids turning a true credit into a wrong answer for the reader’s version.
