Abstract: This paper develops an extensive review of existing literature to examine how right-sided oromotor (mouth and facial motor) asymmetry correlates with speech and language processing in both neurotypical individuals and those with speech-language impairments. Based on studies of babies babbling (Holowka and Petitto, 2002), adults who stutter (Choo et al., 2010), a seven- year-old dysphasic brain dissection (Cohen et al., 1989), and neuroimaging of adults with specific language impairment (SLI) (Badcock et al., 2012), analysis suggests that abnormal lateralization of brain function and brain structure variation may manifest as atypical oromotor asymmetry during speech. While substantial research supports the left hemispher...
