0–3 分鐘：校準句

標註：In my VIEW / the main POI NT 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（/s/–/ʃ/ 對立）

句子：Social media 【HF】ALGORITHMS 【HF】RECOMMEND content that 【HF】CONFIRMS existing 【HF】BELIEFS, creating echo chambers where users rarely encounter 【HF】OPPOSING viewpoints.

標註：SOcial MEdia ALgorithms / recommend CONtent / that conFIRMS / exIsting beLIEFS / creating echo CHAMbers / where users rarely enCOUNter / opposing VIEWpoints.

操作化目標：

Social /ˈsoʊʃəl/ 的 /ʃ/ 舌葉硬顎音 vs. existing /ɪɡˈzɪstɪŋ/ 的 /s/ 舌尖齒齦音
CONFIRMS /kənˈfɜːrmz/ 的 /s/ vs. chambers /ˈtʃeɪmbərz/ 無 /s/ 或 /ʃ/ 在末尾
that、where 弱讀
confirms_existing、users_rarely 連結
VIEWpoints 句尾核重音並下降終止

句 2（/s/–/ʃ/ 對立）

句子：【BUNDLE】The 【HF】consequence is that people increasingly 【HF】INTERACT only with those who share their 【HF】OPINIONS, causing political and social 【HF】POLARIZATION.

9–15 分鐘：超音段焦點與對比（2 句）

句 3（數據對比）

句子：【BUNDLE】Evidence reveals that sixty-four percent of Americans encounter news primarily through social media, where 【HF】ALGORITHMS curate content based on engagement, not accuracy.

讀法 A（強調「64%」這個比例）：

標註：Evidence rEVEALS / that SIXTY-four perCENT / of aMEricans / encounter news primarily / through social media / where algorithms curate content / based on engagement / not accuracy.
核重音在 SIXTY-four perCENT，末端下降終止

讀法 B（強調「參與度而非準確性」的對比）：

標註：Evidence reveals that sixty-four percent of Americans / encounter news primarily through social media / where algorithms curate content / based on enGAGEment / NOT acCUracy.
核重音轉移到 enGAGEment NOT acCUracy，強調優先順序錯誤

句 4（立場保留＋轉折）

句子：【HF】Diverse perspectives can enrich discourse, but when people systematically avoid 【HF】DISAGREEMENT, they become more extreme and less willing to compromise.

讀法 A（轉折邊界清楚）：

標註：DiVERSE perSPECtives / can enRICH disCOURSE / but when people systemATically / aVOID disagreement / they beCOME / more exTREME / and less WILling / to COMpromise.
but 前半終止、後段重新起調；COMpromise 下降終止

標註：Diverse perspectives can enrich discourse / but when people systematically avoid disagreement / they beCOME more exTREME / and less willing to compromise.
核重音落在 beCOME more exTREME，強調極化後果

連續語流目標：

had_designed、to_expose 連結
would be /wʊd bi/ 連結
rather than /ˈræðər ðæn/ 連結但保持清晰
less_polarized 連結
polarIZED 句尾核重音並下降終止

句 6（BUNDLE＋數據引用）

句子：【BUNDLE】This explains why trust in institutions declines while conspiracy theories spread, because echo chambers 【HF】REINFORCE misinformation through repetition without challenge.

標註：This exPLAINS / why TRUST in instiTUtions deCLINES / while consPIracy THEories SPREAD / because echo CHAMbers / reinFORCE / misinforMAtion / through repeTItion / without CHALlenge.

連續語流目標：

This_explains、why_trust 連結
while 弱讀 /waɪl/ 但保持對比標記
because 不可弱化，需形成語塊起點
through、without 弱讀
CHALlenge 句尾核重音並下降終止

句子：Although some platforms have introduced features to 【HF】EXPOSE users to alternative views, most people actively avoid content that challenges their 【HF】BELIEFS; however, civic education could address this tendency.

要點：

Although 與 however 必須獨立成短語塊（前後各有邊界停頓 150–250 ms）
beLIEFS 為前段核重音
TENdency 句尾下降終止，傳達可能解方

句 8（therefore＋結論）

句子：Democracy requires citizens to engage with 【HF】DIVERSE 【HF】OPINIONS and accept complexity; therefore, breaking echo chambers means redesigning systems to prioritize understanding over validation.

標註：DeMOcracy reQUIRES / CItizens to enGAGE / with diverse oPInions / and acCEPT comPLEXity / THEREfore / breaking echo CHAMbers / MEANS / redesigning SYStems / to prioritize underSTANDing / over validAtion.

要點：

and 弱讀 /ənd/
therefore 獨立成語塊並在其後做 150–250 ms 停頓
to 弱讀 /tə/
validAtion 句尾核重音並下降終止，傳達價值導向轉變

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：Social/existing 的 /s/–/ʃ/ 不清楚）	（例：做 5 次 see/she/seat/sheet 對比）	（例：明天加入更多 /s/–/ʃ/ 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：VIEWpoints（觀點多樣性缺失）
句 2：polariZAtion（社會極化）
句 3A：SIXTY-four perCENT / 句 3B：enGAGEment NOT acCUracy
句 4A：COMpromise / 句 4B：beCOME more exTREME
句 5：polarIZED（極化結果）
句 6：CHALlenge（缺乏挑戰）
句 7：TENdency（行為傾向）
句 8：validAtion（從驗證到理解）

替換任務

保留句型骨架，替換關鍵詞練習其他議題：

同溫層 → 認知偏誤：

echo chambers → confirmation bias
reinforce → strengthen
polarize → distort
diverse → balanced

同溫層 → 社群媒體設計：

algorithms → platforms
recommend → suggest
expose → introduce
isolate → segregate
