Potential license inconsistency: GPL-licensed code included in MIT-licensed repo #228
Description
Hi! 👋 Firstly, thanks for the great project and for sharing it.
While reviewing the codebase, I noticed a possible licensing mismatch and wanted to flag it constructively:
- The repository is presented as MIT-licensed.
- The Swift TTS tree includes eSpeak NG at: mlx_audio_swift/tts/Swift-TTS/Kokoro/Frameworks/ESpeakNG.xcframework. That directory contains verbatim eSpeak NG source code.
- Upstream eSpeak NG is GPL-3.0 licensed.
Not legal advice, but the key point is: GPL-licensed source can’t be relicensed to MIT without permission from all copyright holders. If the Swift targets build/link against GPL licensed source, the distributed targets (and any app(s) built using them) need to comply with the upstream license.
Could you clarify the intended licensing for the Swift portion of the project?
