CRAIG WRIGHT LEARNING - VIDEO NARRATION NOTICE These are original slide-by-slide teaching videos with a generic synthetic narrator. They are not recordings of Craig Wright or a clone of his voice. Course text, original examples, diagrams and slides: © 2026 Dr Craig Steven Wright. All rights reserved. The voice provenance below is distinct from the ownership of the original course content. Speech was synthesized locally using Piper 1.8.0, Open Home Foundation's neural speech engine, and the en_GB-alba-medium voice model. No teaching text was sent to an external speech service.

The licensed model generates new speech from this course's written narration; recordings from the source corpus are not copied into these videos. Speech pacing and audio encoding were adapted for lessons. No endorsement by the voice talent, corpus authors or software authors is implied. Captions are rendered visibly in each video. Companion WebVTT files and the complete written walkthrough supply the same spoken material in text. The introductory voice disclosure is part of every video. Pause as needed to read, calculate and compare a worked example; exercise answers are not included in the videos.
