The English, French, Italian and Spanish tutorial narrations are generated with artificial voices. They are translated and timed versions of the original BlauWerk instructions. The screen recordings remain in German.

Speech model: Kokoro-82M (Apache 2.0), generated locally with kokoro-onnx (MIT). Voices: af_heart, ff_siwis, if_sara, ef_dora.

The German diagnostic-report narration uses the original synthetic voice approved by the speaker. Its payment instruction was updated on 16 October 2026 using the same locally generated voice. The German screen recording is unchanged.
