Hypernasality refers to excessive nasal resonance perceived in speech characterized by distinct atypical aerodynamic and acoustic patterns that impact a speaker’s output and intelligibility. As of late, continuous positive airway pressure (CPAP) therapy has been studied as an experimental behavioral treatment approach to treat hypernasality by strengthening the velopharyngeal (VP) closure muscles. This study explored the effects of CPAP training on aerodynamic and acoustic phenomena, with special emphasis on the temporal patterns of velopharyngeal function and vowel space measures. The study was composed of six participants who underwent different training protocols. Aerodynamic and acoustic measurements were obtained before and after 8-week CPAP training. Results indicated that individuals with hypernasality and CPAP training (HN+CPAP) demonstrated a larger magnitude of change in the temporal patterns of velopharyngeal function compared to other controls. Specifically, nasal airflow and intraoral pressure pulse durations decreased with a shift in peak pressure for one participant with hypernasality, suggesting a more typical temporal pattern achieved following CPAP training. No conclusive patterns were observed with regard to vowel space measurements. Findings from this study suggest that CPAP therapy may have different effects on VP function across individuals with varying degrees of hypernasality. Future research is warranted to identify prognostic factors and establish prognostic guidelines in terms of patient selection criteria.
