  "version": "0.1.0",
  "title": "Shadow for prosody, then test spontaneous transfer",
  "summary": "Imitation is the drill; spontaneous speech is the test.",
  "kind": "protocol",
  "body": "Shadow a short, comprehensible reference closely enough to notice timing, stress, reductions and phrasing. Record yourself and compare one chosen feature. Then stop copying the text and speak on a new but related topic. This last step protects against a common error: becoming good at reproducing the model while spontaneous speech remains unchanged.",
  "limits": [
    "Evidence for shadowing is promising but methodologically uneven, and segment-level effects are less clear than global or prosodic effects."
  ],

    "union-language-listening-speaking-and-pronunciation"

  "evidence": [
    {
      "claim": "A 2025 systematic review suggests shadowing can improve comprehensibility, intelligibility, accentedness, fluency and some prosodic features, while evidence for segmental pronunciation is inconclusive and many studies rely on controlled tasks.",
      "source_id": "RS-4A6F00BF230D460B",
      "role": "supports",
      "note": "Shadowing performance should not be treated as evidence that the same gains transfer automatically to spontaneous speech.",
      "locator": "Abstract and discussion"
    }
  ],
  "use_when": [
    "You want to improve rhythm, phrasing, stress or fluency from a strong spoken reference."
  ],
  "avoid_when": [
    "Evidence for shadowing is promising but methodologically uneven, and segment-level effects are less clear than global or prosodic effects."
  ],
  "example": "After shadowing a clear English explanation for chunking and stress, the learner gives an unscripted project update and checks whether phrasing remains less flat.",
  "check": "The selected prosodic feature appears in spontaneous speech, not only in the copied passage.",
  "steps": [
    "Choose 10-30 seconds of clear speech.",
    "Listen for one prosodic feature.",
    "Shadow several times.",
    "Record and compare.",
    "Speak spontaneously on a related prompt.",
    "Check whether the target feature survives."
