Authentic
Swiss German
Synthesis.
The most accurate text-to-speech engine for Swiss German dialects. Transform standard German text into natural sounding Züritütsch, Bärndütsch, and more.
Live Demo
Made for Swiss German.
Not High German pretending to be Swiss.
Our models are trained on carefully curated Swiss German speech data, recorded specifically to capture the unique rhythms, expressions, and regional nuances of the dialects.
Covering Dialects
From Zürich to Wallis, we support specific phonetic nuances of every major Swiss region.
Single & Multi-Speaker
Create natural monologues or two-person conversations with distinct voices and per-speaker dialect control.
Simple API
Drop-in replacement for standard TTS engines. REST API and Python SDK included.
Built together
Plapperi is a collaborative project by Noxenum and SwissNLP, combining applied AI engineering with state-of-the-art research in Swiss German language technology.
