Create game dialogue without booking a studio
Use AI voices, cloned voices, accents, and emotion controls to produce playable game audio faster.
Capabilities
NPC dialogue
Generate quest lines, merchant chatter, tutorial prompts, combat barks, ambient dialogue, and story moments from script blocks.
Voice production controls for game teams
Create dialogue, narration, tutorial audio, and localized game voiceovers with production controls built for iteration.
Scene Context
Context-aware delivery
Generate lines with the surrounding scene in mind, so exposition, mission objectives, tutorial instructions, and character reactions sound connected instead of isolated.
Performance
Emotive character reads
Direct a character toward urgent, whispered, confident, tired, amused, or threatening delivery. Use style instructions and inline cues to make dialogue fit the moment.
Continuity
Recurring character voices
Keep important characters, narrators, and guides consistent across trailers, cutscenes, tutorials, live-ops updates, and localized releases with selected or approved cloned voices.
Iteration
Fast script changes
Regenerate new or changed lines when a quest, tutorial, feature, or story beat changes during development.
Scale
Dialogue at scale
Produce large sets of dialogue blocks for prototypes, narrative branches, tutorials, and post-launch content without splitting the work into scattered files.
Control
Pronunciation and pacing
Control fantasy names, faction terms, item names, pauses, pacing, and emphasis so game-specific language is spoken correctly.
Voice cloning for games
Keep character voices consistent across every branch.
Clone approved voices for recurring characters, narrators, guides, and announcers. Then generate new game dialogue, localized lines, and content updates without booking another recording session for every script change.
Capture an approved character voice
Upload a clean sample from a consented actor, narrator, or internal scratch voice. Use it to create a reusable voice profile for a character, guide, announcer, or quest giver.
Drop approved actor audio
WAV, MP3, or M4A
Lock the voice to the role
Keep important characters consistent across quest branches, tutorial updates, trailers, prototypes, and live-ops content without rebuilding the voice direction every time.
