Who provides Sarah Kerrigan’s voice in StarCraft II?

Tricia Helfer provides Sarah Kerrigan’s voice in StarCraft II.

Helfer voices Kerrigan across the StarCraft II trilogy, including Wings of Liberty, Heart of the Swarm, and Legacy of the Void. Her performance covers Kerrigan’s human identity, her transformation into the Queen of Blades, and the character’s later emotional and political conflicts.

Kerrigan was originally voiced by Glynnis Talken Campbell in the first StarCraft and Brood War. That change in performer is a frequent source of confusion when comparing the original games with StarCraft II. The character remains the same central figure, but the later trilogy uses Helfer’s performance.

Tricia Helfer is also widely known for playing Number Six in the science-fiction television series Battlestar Galactica. Her casting helped give Kerrigan a recognizable voice across StarCraft II’s cinematic and in-game dialogue.
