Licensing & Attribution

Elys Listen combines three separately-licensed pieces. Here is what each one means for a commercial game.

Elys Listen (the plugin)​

Licensed under the terms of your FAB Marketplace purchase (Epic's Fab EULA for code plugins). You may ship it in commercial projects per those terms.

whisper.cpp (bundled inference library)​

whisper.cpp and its GGML runtime are MIT-licensed (Copyright © 2023–2026 The ggml authors). The plugin bundles the library and its license text at Source/ThirdParty/whisper.cpp/LICENSE.

MIT requires that the copyright notice and license text accompany the software. The plugin already ships the license file; we recommend also crediting whisper.cpp / GGML in your game's third-party notices screen or credits.

Whisper models (the .bin files you download)​

The GGML model files are conversions of OpenAI's Whisper weights, which OpenAI released under the MIT license. You may redistribute them inside a commercial game. As with the library, include the attribution (© OpenAI) in your third-party notices.

The models are downloaded from the ggerganov/whisper.cpp repository on Hugging Face by the editor tool; nothing is downloaded at game runtime.

Suggested third-party notice block​

Copy this into your game's credits or THIRD-PARTY-NOTICES file:

This product includes speech recognition powered by:
- whisper.cpp / GGML — Copyright (c) 2023-2026 The ggml authors (MIT License)
- OpenAI Whisper models — Copyright (c) OpenAI (MIT License)

Player privacy​

Elys Listen processes all audio locally. No audio, transcript, or telemetry ever leaves the player's machine — there is nothing to declare under network-data-collection rules for the STT itself. If your game sends the transcribed text to a server, that is your feature to disclose.
