Erickson Donna and Shigeto Kawahara. 2015. Articulatory correlates of metrical structure: Studying jaw displacement patterns (To appear in Linguistic Vanguard). http://user.keio.ac.jp/~kawahara/pdf/ArticulatoryMetricalStructureFinal.pdf.
We propose a rather bold hypothesis that one dimension in which metrical structure manifests itself is jaw movement, and that this may be a better correlate than more commonly discussed features like duration or pitch. My honest feeling is that the hypothesis is too bold, but we would like to hear opinions from experts on other languages. In the paper we mainly discuss English and Japanese.
