Episode notes
Teaching German Without Speaking It
- Joshua built German materials with translated Link mini-stories, audio, and interlinear books using Google Translate.
- He taught his kids German effectively despite not speaking the language himself by producing repetitive audio and printed texts.
From AI Experiments To A Prototype App
- While learning Portuguese, Joshua experimented with AI to generate translated content, audio, and voice clones.
- A friend then prototyped an app that produced bilingual stories with AI voices, proving the concept worked.
Trade Short Drills For Lots Of Input
- Do large amounts of interesting input rather than tiny daily drill sessions to reach fluency faster.
- Aim for hours per day (1–8) to compress the 700-hour threshold for conversational fluency.
