Rôle des contextes lexical et post-lexical dans la réalisation du schwa : apports du traitement automatique de grands corpus

Abstract : Role of lexical and post-lexical contexts in French schwa realisations : benefits of automatic processing of large corpora The role of context is known to affect the realization/deletion of schwa in French. Two large corpora of public journalistic speech (ETAPE) and casual speech (NCCFr), in which schwa realization is defined via automatic forced alignment, are used to examin the contribution of context both within word (lexical) and across word boundaries (post-lexical). Our results highlight the role of the pre-boundary context in the observed schwa deletion rates. If the preceding word ends with a consonant, predictions follow the 3 consonants rule and sonority principles to explain the differences observed in schwa deletion rates. MOTS-CLÉS : chute de schwa, grands corpus, parole spontanée, contexte pré-frontière, alignement forcé .
