“…This enables the game to be modified to address a variety of rehabilitation issues. For example, the speech-processing algorithm could be replaced with a quantitative measure of NAE, as in Cler et al (2016), to give players feedback to reduce their NAE severity. In a similar way, any speech feature that can be reliably measured with microphones and a signal-processing algorithm could be elicited and used to generate appropriate biofeedback for players.…”

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.

Various studies have been conducted to reveal and analyse tissues from humans with distinct properties. The interpretation of human facial tissues was the subject of a few of these investigations. The aim of this study was to look at the energy ratios of vibration signals recorded from the human face using a 3-axis Micro-Electro-Mechanic System accelerometer sensor. 9 various measurement points on the faces of the subjects used to receive the signals are then analysed using frequency characteristics. During the analysis process, wavelet transformation values are estimated and evaluated. Thus, these regions' frequency ranges can be calculated. In addition, critical properties extracted from signals of vibration using wavelet packet transformation analysis were used as inputs of classification methods. In the next step, multilayer perceptual neural networks (MLPNN) were evaluated. In addition, the support vector machine (SVM), decision tree (DT) and binary convolution neural networks (CNN) methods were evaluated, and the success rates were compared. Finally, it is seen that the energy ratios of the signals in the hard regions are low and the energy ratios of the signals in the soft regions are high. And it has been observed that higher accuracy rate is achieved with binary CNN than with other methods.

“…In this figure, the measurement points are identified as F1, F2, F3, around the frontal sinus in the forehead; MR1, MR2, MR3 close to the maxillary sinuses in the right cheek, and ML1, ML2, ML3 close to the maxillary sinuses in the left cheek [20,21]. Also, the vibration motor points are shown as black circles.…”

There are some studies in the literature in order to make the interpretation of human tissues having different characteristics. Some of these studies focused on the evaluation of human face tissues. Vibration signals generated from vocal cords have been used in these studies about human face tissues. However, any study using the vibration signals recorded by applying the external vibration source having fixed frequency value is not available in the literature. In this study, it is aimed to investigate the frequency characteristics of the vibration signals recorded from the human face. These signals obtained from nine different regions on the faces of subjects are analysed using frequency characteristics. In the analysis stage, median and maximum frequency values are calculated and evaluated. So, the softness and hardness interpretation about these regions on the face can be made and the frequency ranges of these regions can be determined. As a result, it is observed that low‐frequency signals are dominant in hard regions and high‐frequency signals are dominant in soft regions.
