本論文研究跨性別女性社群中的共通話題和言語風格，並分析作為跨性別者的立場和自我定位與音調範圍及平均音調之間的關係。研究中除了探討跨性別女性在社群中的共通話題、言語風格、跨性別潛規則和隱藏跨性別身份行為之間的潛在關係之外，在「誰能夠算是跨性別？」的這個問題上，也研究考察了跨性別女性的身分如何影響角色在不同對話中的說話風格。
本研究從台灣的網路論壇 Dcard（跨性別版）和 Discord 上的台灣跨性別交流區中招募了18名跨性別女性。實驗數據收集包含了點餐社交實驗及一對一面談的兩階段過程。點餐社交實驗提供聲學分析方面的研究數據，而一對一面談中探討到不同主題，提供言談分析方面的研究數據。聲學分析著重在音調變化，而言談分析則深入研究有關跨性別者對於跨性別議題的表達及溝通方式。受試者年齡在21到40歲之間，提供本論文有關跨性別者的聲音材料和社交互動的訪談資料。
本研究揭示了跨性別女性獨特的聲調及言談特色。在聲調分析中顯示跨性別族群音調範圍的寬廣特點。受試者被分為高（H）和低（L）音調組，並在其中分析並討論跨性別者在遇到相關問題時的表達方式和使用規避詞等情況。訪談中探討了各種跨性別概念，且表現了不同的跨性別定義和判斷標準的嚴格程度差異。儘管存在一些研究侷限性，本研究提供了有關跨性別聲音、聲音訓練、言語風格和跨性別轉變過程的寶貴見解，對臨床實踐和社會語言學有深遠影響。

This research aims to collect common topics and speech styles within trans woman communities, comparing participants’ pitch values based on their stances and self-positions. It explores potential connections between common topics, speech styles, transgender norms, and the concealment of transgender identity. In addressing the question: “Who counts as trans?” This study places a specific focus on the stances of trans women, exploring whether these stances might have a relative influence on the speech styles of speakers in different conversational roles.
18 trans women were recruited from popular online forums in Taipei, Taiwan—Dcard (Trans Board) and the Taiwanese Transgender Community on Discord. They aged 21 to 40 and provided insights into transgender voices and social interactions. Data collection includes a social interaction experiment (ordering scenario) and one-on-one interviews covering various topics. Acoustic analysis mainly focused on pitch variations, while discourse analysis focused on the expressions of transgender toward transgender issues.
The finding explores the unique acoustic features of trans women, revealing distinct voices within the community. Acoustic analysis highlights trans voice pitch values, categorizing participants into high (H) and low (L) pitch groups with an obvious voice pitch gap between 159Hz and 172Hz. The result uncovers trans women’s cautious expressions and the use of hedging in discussing trans-related issues. The definition discussion also explores transgender concepts, highlighting definitions and strictness levels in different aspects. Despite limitations, the research contributes valuable insights into transgender voices, voice training, speech styles, and the complexities of transitioning, with implications for clinical practices and sociolinguistics.
