“…For such a future application, it may be helpful to know that the present study has already established that knowledge of the task does not appear to diminish the speaker’s compensatory response. Altered auditory feedback could supplement novel experimental interventions such as visual biofeedback of nasality [40-42].…”

Introduction: Previous research has shown that altering the nasal signal level auditory feedback changed the control of oral-nasal balance in normal speakers. The present study investigated whether knowledge of the task and the instruction not to compensate would change the participants’ response to the manipulation. Methods: Twenty participants (10 females) in 2 groups continuously repeated a sentence while their nasal signal level was increased or decreased and fed back to them via headphones, so the speakers heard themselves as more or less nasal, respectively. After the first recording session, participants were debriefed about the true nature of the experiment. They were instructed not to compensate in the second recording session. The outcome measures were the percentage changes of nasalance scores from the first baseline. Results: Statistical analysis using a repeated measures analysis of variance showed an effect of the nasal signal level, F(5,80) = 2.51, p = 0.049, and a nasal signal level by knowledge of task interaction effect, F(5,80) = 3.25, p = 0.019. Post hoc tests showed that the maximum nasal signal level auditory feedback resulted in a significant decrease of nasality from the initial baseline. Conclusion: Despite knowledge of the task, speakers were unable to resist compensating. As found in previous research, there was a numerically higher compensation response at the maximum than at the minimum nasal signal level auditory feedback condition.

“…The normative values developed here provide a starting point for updating clinical standards. Nasometry has undeniable value in a wide range of clinical applications regardless of the patient's age[20,21]. The language tests developed and already in use can be transferred to modern digital devices.…”

IntroductionEvaluation of nasal resonance is an important part of everyday otolaryngological, phoniatric, and speech therapy practice. It allows the detection and monitoring of anatomical and functional abnormalities in the nasal and oropharyngeal cavities. Nasal resonance can be objectively measured by assessing acoustic energy emitted by each of the subject’s nose and mouth. The ratio is called nasalance. The aim of this study was to develop normative values of nasal resonance on a digital device while adults were reading aloud Polish-language material.Material and methodsThe study included 51 patients. Patients were tested with three language tests developed by Gąsiorek in 1996. Nasal resonance was measured using a Nasometer II (Model 6450) from Pentax Medical.ResultsThe mean nasalance in the vowel test was 18.8% (SD = 7.8%). The mean nasalance during the test based on sentences was 14.3% (SD = 4.0%), and for reading continuous text it was 11.7% (SD = 3.7%). Statistical analysis showed no significant difference between men and women on each test. The limiting normative value for nasalance was determined to be 20% in the sentence test (test III of Gąsiorek 1996).Conclusions1. Preliminary normative values of nasal resonance for Polish adults have been established based on current methodology. 2. Language tests developed and already in use can be applied to modern digital devices.

“…We have implemented an algorithmic estimation of nasalization via filtered HONC; feedback on the basis of these estimates has been shown to effect changes in nasalization in healthy speakers over two sessions (Heller Murray, Mendoza, Gill, Perkell, & Stepp, 2016). This same algorithm has been implemented into a video game format, which has been shown to be usable by children in the laboratory in one session (Cler, Voysey, & Stepp, 2015).…”

Purpose Video games provide a promising platform for rehabilitation of speech disorders. Although video games have been used to train speech perception in foreign language learners and have been proposed for aural rehabilitation, their use in speech therapy has been limited thus far. We present feasibility results from at-home use in a case series of children with velopharyngeal dysfunction (VPD) using an interactive video game that provided real-time biofeedback to facilitate appropriate nasalization. Method Five participants were recruited across a range of ages, VPD severities, and VPD etiologies. Participants completed multiple weeks of individual game play with a video game that provides feedback on nasalization measured via nasal accelerometry. Nasalization was assessed before and after training by using nasometry, aerodynamic measures, and expert perceptual judgments. Results Four participants used the game at home or school, with the remaining participant unwilling to have the nasal accelerometer secured to his nasal skin, perhaps due to his young age. The remaining participants showed a tendency toward decreased nasalization after training, particularly for the words explicitly trained in the video game. Conclusion Results suggest that video game–based systems may provide a useful rehabilitation platform for providing real-time feedback of speech nasalization in VPD.
