  "title": "Classify the listening miss before adding more audio",
  "summary": "Not hearing a sentence can mean several different things.",
  "kind": "question",
  "body": "Use the transcript and replay to classify the miss. Was the language genuinely unknown? Was the word known in writing but not recognized from sound? Did connected speech hide the boundary? Was the syntax or meaning too dense even after the words were identified? The repair should match the failure instead of prescribing more generic listening.",

    "These categories are a diagnostic heuristic, not a complete scientific taxonomy of listening comprehension."
  ],
  "example": "If 'could have been' is known on the page but repeatedly disappears in fast speech, vocabulary study is unlikely to be the primary repair.",
  "check": "The learner can name a specific listening failure and a matching next exercise.",
  "question": "Did I know these words before seeing the transcript? · Can I recognize them now from audio alone? · Which boundary, reduction, stress or sound contrast fooled me? · If every word is clear, is the remaining problem syntax or meaning? · What one feature should the next practice target?",
