“…Further electrophysiological evidence for phonological prediction effects has been found for word forms with respect to a speaker's accent (Brunelliere & Soto-Faraco, 2013) as well as during self-initiated speech (Knolle, Schröger, & Kotz, 2013). Predictive mechanisms have been found related to inner speech production (Scott, Yeung, Gick, & Werker, 2013) and may modulate brain responses even down to the level of auditory cortex (Skipper, 2014).…”

“…Just as visual influences on auditory speech processing have long been reported (e.g., Sumby and Pollack, 1954; see Navarra et al, 2012 for review), recent reports have also shown similar effects from articulatory information. For example, subjects’ own silent articulations (Sams et al, 2005; Sato et al, 2013; Scott et al, 2013) influence auditory perception in similar ways as seeing visual speech (although see Mochida et al, 2013). Moreover, receiving haptic or tactile input related to another person’s articulatory movements can also influence auditory speech processing (Fowler and Dekle, 1991; Gick et al, 2008; Gick and Derrick, 2009; Ito et al, 2009; Treille et al, 2014).…”

Speech researchers have long been interested in how auditory and visual speech signals are integrated, and the recent work has revived interest in the role of speech production with respect to this process. Here, we discuss these issues from a developmental perspective. Because speech perception abilities typically outstrip speech production abilities in infancy and childhood, it is unclear how speech-like movements could influence audiovisual speech perception in development. While work on this question is still in its preliminary stages, there is nevertheless increasing evidence that sensorimotor processes (defined here as any motor or proprioceptive process related to orofacial movements) affect developmental audiovisual speech processing. We suggest three areas on which to focus in future research: (i) the relation between audiovisual speech perception and sensorimotor processes at birth, (ii) the pathways through which sensorimotor processes interact with audiovisual speech processing in infancy, and (iii) developmental change in sensorimotor pathways as speech production emerges in childhood.

“…This process results in the first-person conscious experience of the episode of inner speech. The proposal that the predicted state may form the basis of the sensory content of inner speech is supported by recent behavioral studies (Scott, 2013; Scott et al, 2013). …”

The comparator account holds that processes of motor prediction contribute to the sense of agency by attenuating incoming sensory information and that disruptions to this process contribute to misattributions of agency in schizophrenia. Over the last 25 years this simple and powerful model has gained widespread support not only as it relates to bodily actions but also as an account of misattributions of agency for inner speech, potentially explaining the etiology of auditory verbal hallucination (AVH). In this paper we provide a detailed analysis of the traditional comparator account for inner speech, pointing out serious problems with the specification of inner speech on which it is based and highlighting inconsistencies in the interpretation of the electrophysiological evidence commonly cited in its favor. In light of these analyses we propose a new comparator account of misattributed inner speech. The new account follows leading models of motor imagery in proposing that inner speech is not attenuated by motor prediction, but rather derived directly from it. We describe how failures of motor prediction would therefore directly affect the phenomenology of inner speech and trigger a mismatch in the comparison between motor prediction and motor intention, contributing to abnormal feelings of agency. We argue that the new account fits with the emerging phenomenological evidence that AVHs are both distinct from ordinary inner speech and heterogeneous. Finally, we explore the possibility that the new comparator account may extend to explain disruptions across a range of imagistic modalities, and outline avenues for future research.
