Introduction
CALLHOME German Lexicon Second Edition was developed by the Linguistic Data Consortium (LDC) and contains 318,809 German words with morphological, phonological, stress and frequency information. This second edition updates file formats, directory structure and documentation. The first edition is available as CALLHOME German Lexicon (LDC97L18).
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 the CELEX German lexicon (CELEX2 (LDC96L14)) and from 100 training and development transcripts representing unscripted telephone conversations between native German speakers contained in CALLHOME German Second Edition LDC2026S04.
The lexicon contains seven tab-separated information fields: (1) headword: orthographic form; (2) morph: morphological analysis of the headword; (3) pron: pronunciation of the headword; (4) stress: primary stress information of the word; (5) celex: whether the headword appears in the CELEX German lexicon; (6) train_freq: frequency of the headword in the CALLHOME training transcripts; and (7) dev_freq: frequency of the headword in the CALLHOME development 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.orting documentation, schema definitions, and the file table.
