Overview

• The AI model was built on over one million words—including 40,000 unique words and 130,000 sentence pairs—sourced from six decades of Halunder recordings and texts vetted by native speakers.
• Available now, the privacy-compliant, user-friendly translator converts German and other inputs into Helgoländer Friesisch through a web interface.
• With fewer than 100 active speakers—most of whom are elderly—the dialect faces critical endangerment that prompted the digital preservation effort.
• Next phases include a dedicated learning platform for schools and a spoken-variant module to capture the dialect’s audio characteristics.
• Stiftung Lange Anna aims to use the Halunder.ai blueprint to safeguard Helgoland’s cultural heritage and inspire similar efforts for other threatened languages.
