Based on Lexique 3.83

Manuel Gimenes, Cyril PerretBoris New

Lexique-infra is a new database providing infra-lexical indicators for 137,717 words in French coming from Lexique 3.83.

The frequencies of the grapheme-phoneme and phoneme-grapheme correspondences as well as other indicators (consistency, regularity, frequencies of letters, bigrams, trigrams, phonemes, biphones and syllables, etc.).

Several new indicators of consistency and regularity are also proposed: number of irregularities in a word, position of the irregularity, average complexity of the graphemes of a word, frequency of the lowest inconsistency in a word. These indices were calculated by type and token and according to the initial, middle and final positions.
