Abstract
Abstract: Inspired by Beddor 2009, this article explores whether and how trading relations between coarticulatory source and effect may serve as a precursor for sound change. It aims at extending the case of vowel nasalization examined by Beddor to the relationship between closure voicing (source) and co-intrinsic pitch (effect). Through four production and perception studies, we show that the inverse source-effect relation observed for vowel nasalization is not found in the voicing contrast of French, a true-voicing language. Instead, we propose that the phonologization of co-intrinsic pitch (a.k.a. tonogenesis) originates from spontaneous devoicing (a production bias), which subsequently triggers an upweighting of pitch (a perceptual adaptation strategy).*
