Lexique-Infra: grapheme-phoneme, phoneme-grapheme regularity, consistency, and other sublexical statistics for 137,717 polysyllabic French words

Abstract

Psycholinguistic research has shown that both the regularity and consistency of the grapheme-phoneme and phoneme-grapheme correspondences impact word processing. Lexique-Infra is a new database providing infra-lexical statistics for 137,717 French words. The frequencies of the grapheme-phoneme and phoneme-grapheme correspondences as well as other indicators (consistency, regularity, letter frequencies, bigrams, trigrams, phonemes, biphones, and syllables, etc.) are proposed and have been computed from the corpus of subtitles in Lexique 3.83. The aim of this new database is to propose numerous infra-lexical variables based on adult frequencies for a large number of words.
