The problem
Language apps reward streaks, not speaking — so learners can read but freeze when they have to talk.
My contribution
Second brand on the BitSize platform: daily Japanese and French lessons with in-browser speech recognition for pronunciation, native TTS audio, and a JLPT N5–N1 grammar module.
Outcome
Live at bitsizelanguage.com — real-time pronunciation feedback in the browser, no app install.
What I learned
Browser-based speech recognition is good enough for pronunciation feedback — you don’t need a server-side STT pipeline for an MVP. JLPT levels as a content axis are stronger than free-form difficulty tagging because learners already know which level they’re studying for.
