Interactive Game Dialogue
This application area focuses on generating and managing natural-sounding, context-aware spoken dialogue in video games, both for pre-scripted lines and live player interaction. It covers tools and workflows that clean and structure scripts for synthetic voice performance, as well as systems that let players talk to non-player characters (NPCs) in natural language and receive believable, voiced responses in real time. It matters because dialogue is central to immersion, characterization, and gameplay, but traditional pipelines are expensive and rigid: writers must author vast branching scripts, voice actors record thousands of lines, and designers wire everything into dialogue trees and menus. AI-enabled interactive dialogue allows studios to reduce manual authoring and re-recording, improve consistency and quality of performances, and unlock more open-ended, conversational gameplay while keeping production costs and timelines under control.
The Problem
“Real-time voiced NPC dialogue that stays in-character and game-safe”
Organizations face these key challenges:
Dialogue iteration is slow: rewriting, re-recording, and re-integrating lines takes weeks
Voice consistency issues across sessions, actors, locales, and late script changes
NPC interactions feel rigid because branching dialogue explodes in authoring cost
Real-time NPC chat risks lore breaks, spoilers, and unsafe/brand-damaging outputs

Script-to-Voice Batch Dialogue Builder
A writer-facing tool that cleans and restructures scripts (tags, emotions, pauses, pronunciation hints) and generates consistent takes for placeholder or final VO. It produces line-by-line SSML plus a batch TTS render to quickly audition scenes and iterate without re-booking actors. Human review remains the primary quality gate before content enters the build.

Real-World Use Cases
AI Voice Acting Quality Optimization for Video Games
This is about making AI voice actors in games sound more human by first giving them clean, well-written scripts—like making sure an actor’s lines are clear and correctly formatted before you get them into the recording booth.
Ubisoft 'Teammate' Voice AI Tech Demo for Gaming
Imagine an NPC squad-mate in a game that you can talk to like a real person over voice—give them orders, ask questions, or chat—and they understand and respond naturally instead of using clunky button menus.
