This tutorial demonstrates how to implement offline realtime text-to-speech in Unreal Engine using the Runtime Text To Speech plugin.

You’ll learn how to:

  • Download and manage voice models for 40+ languages
  • Synthesize speech from text without internet connectivity
  • Play synthesized audio using Runtime Audio Importer
  • Implement both regular and streaming speech synthesis
  • Work with multi-speaker voice models

The plugin provides complete offline text-to-speech synthesis with 115+ voice models across 40 languages, including high-quality Kokoro models. It’s perfect for accessible interfaces, NPC dialogue, voice-driven tutorials, localization, and procedurally generated content.

Prerequisites: Runtime Text To Speech and Runtime Audio Importer plugins.

Thanks for the guide! I’m currently working on a game for my graduation project, and this will be a great opportunity to try adding voice to my NPCs.
