Effect of nasal speaking valve on speech intelligibility under velopharyngeal incompetence: a questionnaire survey
TLDR
From the results of this study, it was suggested that NSV would be effective in cerebrovascular disease and neurodegenerative disease, as well as in subjects whose speech intelligibility was improved by closing nostrils.Abstract:
Summary
Velopharyngeal incompetence is known as a contributing factor to speech disorders. Suwaki et al. reported that nasal speaking valve (NSV) could improve dysarthria by regulating nasal emission utilising one-way valve. However, disease or condition which would be susceptible to treatment by NSV has not been clarified yet. This study aimed to evaluate the effect of NSV by questionnaire survey using ready-made NSV. Subjects were recruited through the internet bulletin, and NSV survey set was sent to the applicant. Sixty-six participants, who agreed to participate in this study, used NSV and mailed back the questionnaire which included self-evaluation and third-party evaluation of speech intelligibility. Statistical analysis revealed that the use of NSV resulted in significant speech intelligibility improvement in both self-evaluation and third-party evaluation (P < 0·01). Regarding the type of underlying disease of dysarthria, significant effect of NSV on self-evaluation of speech intelligibility could be observed in cerebrovascular disease and neurodegenerative disease (P < 0·01) and that on third-party evaluation in neurodegenerative disease (P < 0·01). Eighty-six percent of subjects showed improvement of speech intelligibility by shutting up nostrils by fingers, and the significant effect of NSV on both self-evaluation and third-party evaluation of speech intelligibility was observed (P < 0·001). From the results of this study, it was suggested that NSV would be effective in cerebrovascular disease and neurodegenerative disease, as well as in subjects whose speech intelligibility was improved by closing nostrils.read more

The effect of Nasal Speaking Valve on the speech under experimental velopharyngeal incompetence condition
TL;DR: The acoustic properties of NSV on the pure VPI condition, which was enabled by the newly established experimental induction, were revealed and this experimental model was proved to provide a basis for the improvement in the treatment modalities for VPI.

Coming to terms with VPI: a response to Loney and Bloem.
TL;DR: A taxonomy for velopharyngeal disorders based on etiology is proposed, which uses diagnostic categories that are clinically meaningful and offer professionals an etiologically based system that can be applied in research and treatment.

Speech-aid prostheses for neurogenic velopharyngeal incompetence
TL;DR: Wire-extension speech-aid prostheses used by the patients were an effective treatment approach for velopharyngeal incompetence and should be carefully tailored for prosthetic treatment because of contingent noncompliance.
