Introduction
CALLHOME Mandarin Chinese Lexicon Second Edition was developed by the Linguistic Data Consortium (LDC) and contains 44,404 Mandarin Chinese words with morphological and phonological information. This second edition updates file formats, directory structure and documentation. The first edition is available as CALLHOME Mandarin Chinese Lexicon (LDC96L15).
The CALLHOME series consists of telephone conversations, transcripts and lexicons developed by LDC and Rutgers, The State University of New Jersey, in support of research in speaker identification, language identification and related technologies. Languages in the series include American English, Egyptian Arabic, German, Japanese, Mandarin Chinese, and Spanish.
Data
The words in the lexicon were derived from transcripts representing unscripted telephone conversations between native Mandarin Chinese speakers contained in CALLHOME Mandarin Chinese Second Edition (LDC2026S11) and from Chinese news text.
The lexicon contains seven tab-separated information fields: (1) headword: orthographic representation of the word in hanzi (e.g., 没有); (2) pinyin: headword transcribed in pinyin (e.g., mei2 you3); (3) tone: tone sequence for headword (e.g., 2 3); (4) pron: pronunciation of headword without tone information (e.g., mey yow); (5) pos: part-of-speech tag for the headword; (6) xinhua_freq: frequency of the headword in newswire text; and (7) train_freq: frequency of the headword in the the CALLHOME transcripts.
The lexicon is presented as tab-delimited TSV file encoded in UTF-8 format. This release also includes a pronunciation dictionary derived from the lexicon in UTF-8 encoded CMUdict format.
