Résumé : Determining the starting point of frication is a complex task involving aerodynamic factors dependent on adjustments controlling articulatory and laryngeal structures and on the regulation of air pressure. This study investigates the aerodynamic characteristics of the onset and offset of Belgian French fricative consonants using direct measurements of subglottal (Ps) and intraoral (Po) air pressure. Results show a higher difference between Ps and Po at the onset of voiced fricative consonants when compared to their voiceless counterparts. This accounts for the need for high air velocity through the glottal and consonantal constrictions for voiced fricatives. The offset of voiced fricatives is also characterized by a relatively large difference between Ps and Po, still lower for voiceless equivalents.
