Japanese audio playback can mispronounce kanji
InvestigatingWhat you'll see When you press the audio button on a Japanese sentence, the text-to-speech engine reads kanji with incorrect or inconsistent readings. In long sentences, this can result in playback that does not sound like natural Japanese.
Why Japanese kanji-to-reading conversion is hard — the same character can have multiple valid readings depending on context, and the current TTS pipeline does not yet use a full Japanese morphological analyzer for pronunciation.
Workaround For now, audio playback is most reliable on single words saved to your dictionary rather than full sentences. Pronunciation for learning practice is best verified against a native dictionary entry.
