Feature Request: AI Text-to-Speech Device for UEFN
Hello Epic Team,
First of all, I want to say that the new Persona / Conversations system is an amazing addition to UEFN. It opens the door to much more immersive storytelling and interactive NPCs.
I would like to suggest a feature that builds on the same technology.
The idea
Create a Text-to-Speech (Narration) Device that allows creators to enter a predefined text and have it spoken using the same AI voice technology as the Persona Device.
Instead of requiring an NPC conversation, creators could simply trigger a text to be read aloud through Verse or device events.
Why this would be useful
This would unlock many new possibilities, including:
- Audio logs
- Story narration
- Radio messages
- Computer or AI announcements
- Museum or exploration guides
- Quest descriptions
- Environmental storytelling
Automatic localization
The biggest advantage would be localization.
Today, if creators want voiced content, they have to record and import separate audio files for every supported language. This quickly becomes impossible because of storage limitations and the amount of work required.
With AI-generated speech, the device could automatically generate the narration in the player’s selected language, just like the Conversations system already supports multiple languages.
This would:
- dramatically reduce project size,
- eliminate the need to store dozens of WAV files,
- make updates much easier (only the text needs to be edited),
- allow even small creators to offer fully localized voice acting.
Why it fits UEFN
Since the Conversations system already combines AI text generation with AI voice synthesis, this feature would reuse the same technology while enabling many non-conversational storytelling experiences.
I believe this would become one of the most valuable tools for narrative creators and adventure maps.
Thank you for considering this suggestion, and thank you for continuing to improve UEFN!
