回饋（90 秒）
回聽今天錄的 8 句，記錄三欄：
| 欄 1：可理解度阻礙點 | 欄 2：可修正機制 | 欄 3：明日最小調整 |
|---|---|---|
| （例：CAPTURE/companies 的 /æ/–/ʌ/ 不清楚） | （例：做 5 次 cat/cut/cap/cup 對比） | （例：明天加入更多 /æ/–/ʌ/ 最小對立詞） |
| （例：however 前後沒停頓） | （例：however 前後各加 200 ms） | （例：所有連接詞強制獨立語塊） |
韻律任務
今天選擇讓以下詞承擔核重音（每句僅一個主核重音）：
- 句 1：vulnerabiLIties（系統性脆弱性）
- 句 2：aGO（時間對比）
- 句 3A：MAXimize enGAGEment TIME / 句 3B：psychoLOGical COST
- 句 4A：BANDwidth / 句 4B：deLIBerately FRAGment
- 句 5：adoLEScents（受影響族群）
- 句 6：duRAtion（衡量指標）
- 句 7：MINimal（監管不足）
- 句 8：TACtics（理解對策）
