語音實驗室 - Phonetics Lab Homepage

The major differences of my research frommost phoneticians are the topics and methods. My collaboration with speech scientists and engineers dates back to 1982, which has led me away from studying limited samples and numbers of speakers toward multiple speakers, larger chunks of more realistic speech, and larger quantities of data (though modest by speech technology community standards). My research has integrated techniques from engineering and speech technology into acoustic phonetic experimental studies. My investigation of Mandarin Chinese fluent speech prosody beyond the sentence level begins from a macro/top-down perspective, taking intonation units larger than the phrase or sentence into consideration, has resulted in the emergence of what I believe to be the defining feature of fluent speech prosody: systematic cross-phrase prosodic association, which constitutes prosodic context. This approach contrasts with analyses of discourse intonation based on patterns of individual phrase intonation. Using quantitative evidence, she has developed a hierarchical prosodic framework, which models the formation of spoken discourse prosody as the accumulation of multi-layered prosodic contributions. I have also been able to tease apart the contributions to cross-phrase prosodic association made by each layer of the prosodic hierarchy for a range of acoustic parameters for which, interestingly, the contributions made by supra-segmental acoustic correlates have been found to vary. As of 2008, I have also begun phonetic comparisons of L1 and L2 English (with a focus on prosody) as a member of AESOP (Asian English Speech cOrpus Project).

1999-2006年間，語音實驗室召集人帶領研究團隊開發語料庫語音學研究方法，設計語音資料庫，收集大批語料，捨棄個別語料觀察，率先開發了研究課題導向語料庫語音學的研究方法，從語料庫語言學探討超音段語音訊息。復以計算語言學方法驗證，建立口語語篇的韻律模型，提出「階層式多短語語流韻律HPG架構」(Hierarchical Prosodic Phrase Grouping)  (Tseng et al2004; 2005) 的說法，走出傳統語音學著重質的觀察不重語料量的計算的限制。在實驗語音學方面，專攻口語韻律中的上層結構，把語音學帶出一向只重語音細節、只觀察極小的語音單位，卻無力處理大範圍語音單位，以致研究結果多為見樹不見林的不足困境。在語料庫語言學方面，創新語音資料庫的設計、語料收集的特性、標註系統的開發、標註結果一致性的取得等工具庫的設計。在計算語言學方面，採用語料庫研究，勢必要做大規模的量化處理，因此也將實驗語音學的研究，從觀察聲波、採用套裝統計軟體的方式，提升到配合理論架構、調整量化方式的層次。COSPRO收集了九套口語韻律語流的資料庫，容量共共10.58GB，在2006年一月配合標註、工作平台一併釋出，對語音學研究提供具體的資源及建構平台知識的分享。（請參看中研院口語韻律語料庫 Sinica Continuous Speech Prosody Corpora & Toolkit 的網址）。

2009年起，開始研究L2英語的研究，設計並收集亞洲口音英語跨國語音資料庫─建構多人次台灣口音英語語音資料庫TWNAESOP (TaiWaN Asian English Speech cOrpus Project)，建立一個代表亞洲口說英語多樣性的亞洲英語語音資料庫及平台。召集人以台灣代表身份應邀參與，將負責該資料庫共同核心內容之設計，及蒐集核心語料中台灣地區英語的語料。本計畫的目標除完成上述工作外，也將同時設計並收集台灣口音英語全面性的語音資料。
