Why does Duolingo 5.3.2 flag my native‑like Japanese pitch‑accent as a pronunciation error?
Spent the last 200 hrs grinding the Anki deck for the new NHK 2‑Lesson series (including the 0‑2‑1‑3‑5 pitch‑accent patterns) and hit C2 on the CEFR scale, yet the Duolingo speaking test keeps marking my intonation as "incorrect".
- The app uses a generic acoustic model (v2.7) that doesn't even differentiate between mora length and pitch.
- My IPA transcription for "はし" (hashi) correctly shows [haɕi] vs [haɕiː] but the feedback just says "pronunciation needs work".
- Even after calibrating the mic and running the built‑in noise‑cancellation, it still thinks I'm mumbling.
Anyone else notice that these platforms treat advanced phonetic nuance like a bug? Or am I just being picky because I finally got my Japanese‑specific HRTF headset working and expect the software to keep up? Looking for tips or a rant‑partner.
