The timing and sequencing of coarticulated non-modal phonation in English and White Hmong

► We study whether breathy-to-creaky phonation contours are found in English and Hmong. ► Contrastive breathiness or creakiness is more extensive than non-contrastive non-modal phonation. ► Non-contrastive breathiness in the two languages behaves similarly. ► Contrastive breathiness in Hmong is less differentiated from modal but differs more in intervals than non-contrastive variety. ► Breathy and creaky phonation can occur simultaneously in the acoustic output for Hmong.
