The aerodynamics of nasalization in French

Nasalization in French involves a complex interplay between several phonetic and phonological factors that have been, for the most part, investigated separately over the last 40 years. The present study provides a detailed account of the aerodynamics of French nasalization from eight Belgian French speakers reading word lists. Patterns of tautosyllabic nasal coarticulation are investigated in CV˜, NV˜, CV˜C, CV˜.CV, CV, NV, (C)VN, and NVN items, comparing different vowel and consonant types. Dependent variables involve temporal measures of both the extent of nasalization and its starting point relative to the oral–nasal boundary, and average flow rates across the acoustically defined segments. Results confirm previous findings that carryover nasalization is more extensive than anticipatory nasalization in French for both vowels and consonants. We further show that the temporal extent of intra-syllabic nasal coarticulatory airflow varies across vowel height and consonant manner of articulation and voicing. Various factors are considered in accounting for this variation.
