Introduction
CALLHOME Spanish Lexicon Second Edition was developed by the Linguistic Data Consortium (LDC) and contains 45,547 Spanish 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 Spanish Lexicon (LDC96L16).
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 80 transcripts representing unscripted telephone conversations between native Spanish speakers contained in CALLHOME Spanish Second Edition LDC2026S04 and from various Spanish news texts.
The lexicon contains nine 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) callh freq: frequency of the headword in CALLHOME transcripts; (6) madrid freq: frequency of the headword in Madrid Radio transcripts; (7) ap freq: frequency of the headword in Associated Press newswire; (8) reut freq: frequency of the headword in Reuters newswire; and (9) norte freq: frequency of the headword in El Norte newswire.
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 and the grapheme-to-phoneme (G2P) tools used to automatically generate pronunciations for the original lexicon.
