How Sydney learned to speak Xenomorph
Chandler worked with the film’s creative team to bring the alien vocalizations to life. She practiced the sounds as part of her performance, rather than simply mouthing along and letting sound designers add everything later. In short, the production expected her to produce convincing vocal material on set so the visuals and sound matched naturally.
Techniques used
The methods were practical and actor-focused. For example, Chandler used breath control and throat-placement exercises to create low, guttural tones. She also matched her mouth and body movements to the sounds so the alien voice lined up with the performance. Physical coordination with prosthetics and camera blocking was part of the work too, since timing matters when a creature seems to be speaking.
On-set recording and post-production
Recordings were captured during takes, and the sound team then refined those elements in post-production. Thus, the final alien voice is a combination of Chandler’s on-set performance and the sound department’s editing, layering, and effects. This approach preserved the actor’s timing and emotional intent while allowing additional texturing in the mix.
Why it mattered
The result is more believable performances and stronger interplay between actor and creature effects. Because Chandler provided real sounds on set, editors and sound designers had authentic material to work with, which helped the film maintain consistent rhythm and emotional beats across scenes.
In short: Chandler didn’t just pretend to speak Xenomorph — she learned and performed the sounds, collaborated with the production’s voice and sound teams, and helped make the alien language feel anchored to the on-screen action.
