“…Nevertheless, controversy exists over the precise definition of speech rhythm (e.g., Arvaniti, 2007;Dauer, 1983;Kohler, 2009), with alternative suggestions being that prosodic properties may underpin the rhythmic continuum (e.g., Arvaniti, 2007;Dauer, 1983;Prieto, del Mar Vanrell, Astruc, Payne, & Post, 2012), or that rhythm may involve perceptual grouping on the part of the listener (e.g., Arvaniti, 1994;Dauer, 1983;Lee & Todd, 2004;Lehiste, 1977). Notwithstanding this controversy, the evidence is considerable that infant speech perception quickly tunes into the rhythm of native language and that such effects persist in adult speech perception (e.g., Kim, Davis, & Cutler, 2008;Mehler, Dommergues, Frauenfelder, & Segui, 1981;Nazzi, Bertoncini, & Mehler, 1998;Nazzi, Iakimova, Bertoncini, Fredonie, & Alcantara, 2006).…”
