...speech signal to recover phonetic information? Based on a constructivist approach of perception (Helmholtz, 1867), several theories of speech perception argue that the speaker and the listener share a common repertoire of sensory and motor primitives and that speech perception is partly driven by a process of internal sensory-motor simulation that serves to constrain the phonetic interpretation of the sensory inputs (Liberman et al., 1967; Stevens and Halle, 1967; Liberman and Mattingly, 1985; Liberman and Whalen, 2000; Schwartz et al., 2002, 2012; for recent reviews, Galantucci et al., 2006; Schwartz et al., 2008). The constructivist approach is also at the core of recent distributed brain network models of speech processing (Callan et al., 2004; Wilson and Iacoboni, 2006; Hickok and Poeppel, 2007; Skipper et al., 2007; Poeppel et al., 2008; Rauschecker and Scott, 2009; Hickok et al., 2011; Rauschecker, 2011). These models postulate the existence of a left posterior dorsal (‘how’) processing stream, linking auditory speech representations in the auditory cortex and articulatory representations in the ventral premotor cortex (vPM) and the posterior part of the inferior frontal gyrus (pIFG), with sensori...
