0–3 分鐘：校準句
句子：In my view, the main POINT is simple, but the details matter.
標註：In my VIEW / the main POINT is SIMple / but the deTAILS MATter.
要點：
- 功能詞弱讀：in /ɪn/, my /maɪ→mɪ/, the /ðə/, is /ɪz→z/, but /bət/
- 句尾 MATter 下降終止，明確收束
- but 前後形成邊界（前段半終止、後段終止）
三遍法：
- 第 1 遍：慢速，只求重音位置正確
- 第 2 遍：正常語速，加上自然節奏
- 第 3 遍：錄音一次
3–9 分鐘：音段對立（2 句）
句 1（/θ/–/ð/ 對立）

標註：TESTing DRUGS / on ANimals / CAUSes SUFfering / THOUGH supPORTers ARgue / the BENefits OUTweigh / the Ethical COSTS.
操作化目標：
- though /ðəʊ/ 濁音 /ð/，舌尖輕觸上齒，聲帶震動
- ethical /ˈeθɪkl/ 清音 /θ/，舌尖位置相同但不震動
- the /ðə/ 濁音需與 outweigh /ðiː/ 區分
- on、the（兩次）弱讀
- on_animals、the_benefits、the_ethical 連結
- COSTS 句尾核重音並下降終止
句 2（/θ/–/ð/ 延伸）
句子：【BUNDLE】The key issue is whether we can 【HF】JUSTIFY harming thousands of animals to 【HF】SAVE human lives.
標註：The KEY ISsue / is WHEther we can JUStify / HARMing THOUsands of ANimals / to SAVE HUman LIVES.
操作化目標：
- The /ðə/ 濁音
- whether /ˈweðə/ 濁音 /ð/
- thousands /ˈθaʊzndz/ 清音 /θ/，需清楚送氣
- is、we、can、to 弱讀
- whether_we、thousands_of 連結
- LIVES 句尾下降終止
9–15 分鐘：超音段焦點與對比（2 句）
句 3（數據對比）
句子：In the UK alone, researchers 【HF】USE over three million animals per year in experiments, not three hundred thousand.
讀法 A（強調 300 萬這個數字）：
- 標註：In the UK aLONE / reSEARCHers USE / over THREE MILlion ANimals / per YEAR / in exPERiments / not three hundred thousand.
- 核重音在 THREE MILlion，末端下降終止
讀法 B（強調「不是 30 萬」的否定）：
- 標註：In the UK alone / researchers use / over three million animals per year / in experiments / NOT three hundred THOUSAND.
- 核重音轉移到 THOUSAND，NOT 前語調略抬形成對比
句 4（立場保留＋轉折）
句子：【BUNDLE】On the one hand, animal models help us 【HF】DEVELOP life-saving treatments, but on the other, ninety percent of drugs that pass animal trials fail in humans.
讀法 A（轉折邊界清楚）：
- 標註：On the ONE HAND / animal MODels / HELP us deVELop / life-SAving TREATments / but on the OTHer / NINEty perCENT of DRUGS / that PASS animal TRIals / FAIL in HUmans.
- but 前半終止、後段重新起調；HUmans 下降終止
讀法 B（焦點在失敗率）：
- 標註：On the one hand / animal models help us develop life-saving treatments / but on the other / NINEty perCENT of drugs / that pass animal trials / FAIL in HUmans.
- 核重音落在 NINEty perCENT 與 FAIL，強調矛盾

連續語流目標：
- would not /ˌwʊd ˈnɒt/ 不縮約（強調）
- have_needed 連結
- were_not 連結但 NOT 保持重音
- on_animal 連結
- SUFfered 句尾核重音並下降終止
句 6（BUNDLE＋數據引用）
句子：【BUNDLE】This raises conCERNS about whether the Three Rs principle—【HF】REPLACE, 【HF】REDUCE, and Refine—is being taken seriously, given that usage rates remain at historic highs.
標註：This raises conCERNS / about whether the THREE Rs PRINciple / rePLACE / reDUCE / and reFINE / is BEing TAken SEriously / GIVen that Usage RATES / reMAlN / at hiSTORic HIGHS.

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：though 的 /ð/ 聽成 /d/） | （例：做 5 次 /θ/–/ð/ 極化對比） | （例：明天加入更多齒間音對比詞） |
| （例：Three Rs 說太快聽不清） | （例：Replace/Reduce 各停頓 150 ms） | （例：所有列舉項目強制加停頓邊界） |
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：COSTS（倫理代價）
- 句 2：LIVES（人命價值）
- 句 3A：MILlion / 句 3B：THOUSAND
- 句 4A：HUmans / 句 4B：FAIL
- 句 5：SUFfered（受苦焦點）
- 句 6：HIGHS（使用率批判）
- 句 7：SCIence（科學品質）
- 句 8：inDEFinitely（不可持續警告）

- alternative methods → living donation
動物實驗 → 太空探索：
- animals → astronauts
- experiments → missions
- ethical costs → budget priorities
- life-saving treatments → scientific discovery
