Does Sibillo Audio – Text to Speech, AI Voices & Podcast Feeds trigger an EU AI Act Article 50 duty?
by wpvoicer
Verdict — duty applies
Article 50(2) — synthetic content must be marked
This tool generates synthetic content. Article 50(2) places a marking duty on providers of generative systems — output should be marked machine-readably as AI-generated — and deployers publishing that content carry the practical transparency expectations that follow from it.
Voice & speech: where this tool sits
Text-to-speech, voice cloning, speech recognition. Synthetic audio carries the marking duty, and cloned voices of real people are deepfakes with an explicit disclosure obligation.
A cloned or synthetic voice that could be mistaken for a real person is exactly what Article 50(4) was written for.
What you must show
- Keep provenance: know which published content came from this tool.
- Where the content informs the public and no human takes editorial responsibility, disclose that it's AI-generated (Article 50(4) text duty).
- Prefer tool settings that embed machine-readable marking where offered.
A disclosure you can adapt
