Battle grunts, effort sounds, hit reactions, and death cries sit at the core of immersive combat audio. Players notice when a character’s response to a sword strike or fall feels flat or repetitive. Yet these non-dialogue vocalizations remain one of the most overlooked and physically demanding parts of game voice work.
Voice actors routinely describe sessions that include long lists of specific efforts: multiple takes of punches to the face or gut, kicks to the ribs, burns, falls from height, and choked death sounds. J.B. Blanc, known for roles including Rost in Horizon Zero Dawn, has explained that these are fully scripted, not improvised, and that the volume and repetition can exhaust the voice long before dialogue is finished. In many projects the entire session may consist of nothing but exerts. Actors and directors frequently report that placing the most punishing material at the end of a session is the single most practical safeguard, yet inconsistent studio practices still leave talent vulnerable.
Vocal strain is not theoretical. A recent survey of video game voice actors found that nearly 89 percent experienced voice-related symptoms from their work, with hoarseness, reduced range, and partial voice loss among the most common. Recovery often stretches across multiple days. ACTRA Toronto’s guidelines on extreme voice performance list battle chatter, onos (pain reactions), and death screams as inherently high-risk, noting the force and explosive vibration required. A pilot study published in the Journal of Voice examined Vocal Combat Technique training—focused on hygiene, resonance, breath support, and specialized methods for yells and screams—and found measurable reductions in acoustic perturbation measures and self-reported discomfort after training.
Practical recording habits make the difference between usable takes and damaged instruments. Warm-ups matter: gentle humming, lip trills, and sirens prepare the folds without forcing them. Many experienced performers pair this with light physical movement—push-ups or jogging in place—to engage the body the way combat does. Power comes from the diaphragm and core rather than the throat. Open vowels (“ah,” “oh,” “uh”) and visualizing the exact location of an impact produce more natural variation while reducing glottal slam. Hydration is non-negotiable; water and non-menthol lozenges stay within reach, caffeine and dairy stay off the table. Breaks every 45–60 minutes, during which the actor remains on vocal rest (no talking, not even whispering), allow recovery inside the session itself.
Microphone technique and signal management address the other half of the problem: clipping and distortion. Recording at healthy levels, maintaining consistent distance and angle, and leaving headroom prevent the peaks that post-production cannot fully repair. Engineers set levels before the high-intensity takes begin so the actor does not have to push harder simply to register on the meter. When efforts are captured cleanly, editors gain usable variations instead of clipped or compressed files that sound artificial in the mix.
These practices are still unevenly applied across studios. Some sessions schedule extreme material first or run without adequate breaks. Others treat efforts as an afterthought rather than a core performance element that requires the same preparation as dialogue. The result is both talent burnout and inconsistent audio assets that require heavy processing or re-recording.
Studios that treat combat vocalizations as skilled performance rather than raw volume achieve better results. Clear scripting of variation, reference animations when available, and collaboration between directors, engineers, and actors reduce the number of takes needed. The goal is authenticity that holds up under repeated playback without costing the performer their instrument.
When localization extends these assets into new languages and markets, the same care becomes essential. Artlangs Translation has spent more than two decades specializing in game localization, multilingual dubbing for games and audiobooks, short-drama subtitle localization, video localization, and multilingual data annotation and transcription. With proficiency across more than 230 languages and a network of over 20,000 professional linguists and voice talent, the company has supported numerous high-profile projects that require precise handling of both dialogue and non-verbal performance elements. Consistent standards for combat efforts translate directly into higher-quality localized audio that maintains immersion across regions.
