中心宗旨

本中心基於「推動國家語言整體發展方案」的政策目標、並呼應聯合國教科文組織所倡議的「多語並存」與「語言多樣性維護」的理念，旨在貢獻語言學家專業意見，建置以典藏本土語言特色主題為導向的語言資源共享平台。首要目標為永續維護臺灣的語言多樣性，以傳承各族群文化裡都不可或缺的「語言」。我們由橫向與縱向的時空軸線來進行。就共時橫向比較而言，我們分別由（甲）語音、音韻及其介面、（乙）語意與語法類型、（丙）心理與腦神經語言學，（丁）語言接觸與變遷等四大面向來紀錄、分析並典藏臺灣語言裡的各種特色主題。就歷時縱向跨度而言，除了探究從十七世紀以來中土與域外文獻裡反映出在閩南語發生的種種演變以外，更試圖重構臺灣漢語與南島語間的語言接觸史，以期擴展本土語言的歷史縱深。

四大主題資料庫的建立將有效整合語言學不同領域的研究成果、進而推動數位時代的臺灣語言永續傳承。我們也期盼透過科普文章的刊登，將相關研究介紹給普羅大眾，提升民眾對臺灣的語言現況認識和激發其對語言學的興趣。本土語言語料庫為一跨平台（教育部閩南語辭典、客語辭典、族語e樂園、本中心）、跨語言（台灣本土語言以及新住民的母語（目前為越南語））的語料庫。創新之處在於跨語言的整合性搜尋功能，便於比較不同語言和方言的語音、語法及詞彙等。

本計畫對「推動國家語言整體發展方案」所著重的語言教學、語言認證、人才培育及書寫系統發展等目標，乃至於本土語言文化相關產業，均可提供實證語料數據，進而永續保存臺灣語言的多樣性。更能提供優質的語料，促進臺灣本土的大語言模型的建置。

The Center for Sustainable Development of Linguistic Diversity in Taiwan (SDLD) aligns its mission with the "National Language Development Plan" and UNESCO's principles of multilingualism and linguistic diversity preservation. SDLD aims to leverage linguists’ expertise in establishing a comprehensive digital archive of Taiwan's indigenous languages, with the primary objective of sustainably maintaining the nation's rich linguistic diversity.

Our methodological approach encompasses both synchronic and diachronic analyses: Synchronically, we employ a multifaceted framework to document, analyze, and archive distinctive features of Taiwanese languages across four primary domains: (a) Phonetics, phonology, and their interfaces, (b) Semantics and syntactic typology, (c) Psycholinguistics and neurolinguistics, and (d) Language contact and change.

Diachronically, our research extends beyond investigating the evolution of Southern Min as reflected in 17th-century onwards mainland and overseas documents. We also endeavor to reconstruct the historical trajectory of language contact between Sinitic and Austronesian languages in Taiwan, thereby expanding our understanding of the historical depth of local languages.

The development of four thematic databases serves to synthesize research outcomes from diverse linguistic subfields, facilitating the digital preservation and continuous transmission of Taiwanese languages. Additionally, we aim to disseminate our findings through accessible science popularization articles, enhancing public awareness of Taiwan's linguistic landscape and fostering broader interest in linguistics.

SDLD's linguistic corpus represents a pioneering cross-platform, multilingual resource, integrating data from various governmental and institutional sources, including online dictionaries, e-learning platforms, and fieldwork data. The corpus features an innovative cross-linguistic search function, enabling comparative analysis of phonetic, grammatical, and lexical features across languages and dialects. 

 This initiative directly supports the objectives outlined in the "National Language Development Plan," offering empirical linguistic data crucial for language pedagogy, proficiency assessment, talent development, and orthographic standardization. Furthermore, it contributes to the preservation of Taiwan's linguistic diversity and provides high-quality data for the development of indigenous large language models.

By fostering rigorous research, empowering local communities, and advancing linguistic scholarship, SDLD not only ensures the vitality of Taiwan's linguistic heritage but also contributes significantly to the global discourse on linguistic diversity. Our work underscores the irreplaceable value of each language as a unique window into human cognition and culture.
