從兒童語言語料庫提取詞頻：發展心理語言學研究的新工具

// Extracting Word Frequencies From Child Language Corpora: A New Tool for Developmental Psycholinguistic Research

本研究介紹childeswordfreq，一款用於從CHILDES兒童語言資料庫提取詞頻數據的R語言工具｜透過比對CHILDES與成人語料庫SUBTLEX-US的詞頻，揭示出與發展階段相關的差異｜結果顯示兒童語音頻率與成人標準不同，強調兒童語料對語言習得研究的重要性，提升語言輸入分析的準確性與生態效度。

// The study introduces childeswordfreq, an R tool for extracting word frequency data from the CHILDES child language database to aid research on language development. The tool was tested by comparing word frequencies from CHILDES with adult-language frequencies from SUBTLEX-US, revealing differences tied to developmental stages. Results show child-directed speech frequencies differ from adult-based norms, emphasizing the importance of child-centered data in language acquisition research. This tool facilitates more accurate, ecologically valid analyses of child language input.
