<div>Direct voice training interventions resulted in improvements in both the oral phase (e.g., improved tongue strength, better bolus control) and the pharyngeal phase (e.g., modified glottal closure and laryngeal elevation, improved maximal opening of the pharyngoesophageal sphincter, improved rising and falling times of laryngeal muscle groups) in individuals with oropharyngeal dysphagia (OPD). Studies also found that voice training interventions improved maximum phonation time. The authors conclude that "both the promotion of laryngeal elevation and vocal fold closure function demonstrates that voice intervention training can improve swallowing function in OPD patients" (p. 982). Due to the small number of included studies, additional research on voice training intervention for dysphagia is warranted.</div>
