How the audio is made

Every Luxembourgish line on MoienLab comes from one practice corpus of 1,186 items across 57 lessons, written by hand rather than machine-translated. The audio for each line was generated with a single approved voice. The A1 starter lessons were reviewed and approved by a native Luxembourgish speaker before launch; the A1.2, A2 and B1 levels were written to the same corpus rules and generated with the same approved voice and settings, and the whole corpus was swept again for spelling and the Eifeler Regel in August 2026. The corpus is checksummed: lines do not silently change, and audio always matches the text you see. Use it for rhythm: play a line, repeat it, move on. Every exercise on the site works with the audio switched off.

That is also why MoienLab shows no testimonials or user counts yet: the site is new, and we would rather earn trust with method than invent it.
