Overview

Traditional game audio pipelines require pre-recording every line of dialogue per character per language. Resemble AI replaces that with runtime voice synthesis: build a distinct cloned voice for each NPC, then generate dialogue dynamically based on player actions, quest state, or procedurally generated content.

The Unreal Engine integration exposes Resemble's streaming TTS through a plugin that slots into Blueprint and C++ workflows. Studios can prototype voiced dialogue in hours instead of months, localize entire games into 90+ languages from a single voice per character, and build emergent NPC conversations that weren't possible with pre-recorded audio.

Features

Per-character voice cloning

Build a distinct, consent-verified voice for every NPC. Protagonist, villain, merchant — each gets a recognizable vocal identity.

Runtime dialogue generation

Synthesize dialogue on the fly based on player choices, world state, or procedural content. No pre-recording required.

Emotion and style control

Direct performances per line — angry, whispered, triumphant. Match delivery to combat, stealth, or cinematic beats.

Localization at ship time

Generate every NPC's dialogue in 90+ languages from a single source voice. Cut localization cost and time dramatically.

Blueprint and C++ plugin

Drop the Resemble plugin into any Unreal project. Call TTS from Blueprint nodes or C++ game logic with low-latency streaming.

Voice ownership and rights

All cloned voices are consent-verified and licensed for commercial game use. Protect your studio from IP and likeness disputes.

Use cases
