Nowadays, the use of mobile application is most important thing in the healthcare sector is increasing rapidly. Mobile technologies not only for communication for multimedia content (e.g. clinical audio-visual notes and medical records) but also promising solutions for people who desire the identification, monitoring, and treatment of their health conditions anywhere and at any time. Mobile E-healthcare systems can contribute to make patient care faster, better, and cheaper. Several pathological conditions can benefit from the use of mobile technologies. In this paper we focus on dysphonia, an alteration of the voice quality that affects about one person in three at least once in his/her lifetime. Voice disorders are rapidly spreading, although they are often underestimated. Mobile health systems can be an easy and fast support to voice pathology detection. The identification of an algorithm that discriminates between pathological and healthy voices with more accuracy is necessary to realize a valid and precise mobile health system. . This technique is evaluated by based on experimental results deep neural networks with machine learning approach to provide an accuracy of 99.89% in detecting voice. In this field to detect any abnormal structure and analysis without human intervention in health care sector to enhance the utility of well beginning system.

ABSTRACT Objective: to analyze the association between voice disorder and aspects related to breathing mode in children, according to sex. Methods: 250 children, aged six to nine years, attending a public school in São Paulo city, were selected. The collection consisted of spontaneously audio recorded speech samples. The breathing mode was evaluated for lip resting posture and nasal flow. Three audiologists performed the perceptual evaluation of the voice quality, with the help of GIRBAS scale. The results were associated using the chi-square test (p = 0.05). Results: 50.4% females and 49.6% males. As for the overall grade (G), 12.8% had voice disorder with respect to voice quality. In the breathing mode, 36.8% presented alterations in lip posture and 71.2%, in nasal flow. The associations between voice disorder and gender (p = 0.96), lip posture (p = 0.38) and nasal flow (p = 0.18) and between alterations in the nasal flow and sex (p = 0.449) were not confirmed. The association between lip posture and sex revealed significant differences in favor of males (p = 0.003). Conclusion: there was no statistically significant difference associating voice disorders with breathing mode (lip posture and nasal flow) and gender.

Spasmodic dysphonia (SD) is a voice disorder that leads to strained or choked speech. SD is unresponsive to speech therapy. There is no cure for SD. Preliminary work from our group showed that voice quality in SD improves when vibro-tactile stimulation (VTS) is applied over the larynx as a non-invasive form of neuromodulation. The goal of this paper is to describe the design and development of a non-invasive wearable device, which applies VTS to laryngeal muscles with the aim to improve voice quality of individuals with SD. This paper provides preliminary data about the effectiveness of this wearable device for treating the voice symptoms associated with SD.

Puberphonia is a rare disorder, in which the patient manifests higher register voice than others of their same age group. Manifestation is less in women than men. The prevalence is 1 in 900,000. Apart from impact on voice of patient, puberphonia also has impact on the psycho-social aspect. Different treatment modalities have been put forward in the past, many of which lack validity and EBP. Voice therapy has proven to be the most effective in the management of puberphonia. Voice Handicap Index (VHI) is a tool for assessing the perceived handicap by the patient. VHI has 3 parts and overall score of 120 and individual subset has score of 40 each. Result: Patient who received voice therapy obtained better score on the overall scale as well as on each subsets of the VHI. Conclusion: The study concludes that the voice therapy not only improves the voice quality of the patient, but also improves the quality of life of the patient. The impact of voice disorder (puberphonia) is most prominent on the emotional section. Keywords: Puberphonia; voice therapy; VHI.

The characterization of voice quality is important for the diagnosis of a voice disorder. Vocal fry is a voice quality which is traditionally characterized by a low frequency and a long closed phase of the glottis. However, we also observed amplitude modulated vocal fry glottal area waveforms (GAWs) without long closed phases (positive group) which we modelled using an analysis-by-synthesis approach. Natural and synthetic GAWs are modelled. The negative group consists of euphonic, i.e., normophonic GAWs. The analysis-by-synthesis approach fits two modelled GAWs for each of the input GAW. One modelled GAW is modulated to replicate the amplitude and frequency modulations of the input GAW and the other modelled GAW is unmodulated. The modelling errors of the two modelled GAWs are determined to classify the GAWs into the positive and the negative groups using a simple support vector machine (SVM) classifier with a linear kernel. The modelling errors of all vocal fry GAWs obtained using the modulating model are smaller than the modelling errors obtained using the unmodulated model. Using the two modelling errors as predictors for classification, no false positives or false negatives are obtained. To further distinguish the subtypes of amplitude modulated vocal fry GAWs, the entropy of the modulator’s power spectral density and the modulator-to-carrier frequency ratio are obtained.

This article describes how the exponential growth of mobile applications has changed the way healthcare services function, and mobile healthcare using the Cloud is the most promising technology for healthcare industry. The mobile healthcare industry is in a continuous transition phase that requires continual innovation. There has been identified some of the challenges in the area of security protocols for mobile health systems which still need to be addressed in the future to enable cost-effective, secure and robust mobile health systems. This article addresses these challenges by proposing a secure robust and privacy-enhanced mobile healthcare framework (SRPF) by adopting a Community Cloud (CC), WPKI cryptosystems, Universal Integrated Circuit Cards (UICCs) and a Trusted Platform Module (TPM). All the security properties are provided within this framework. SRPF overcomes replay attacks, Man in the Middle (MITM) Attacks, Impersonation attacks and Multi-Protocol attacks as SRPF was successfully verified using a scyther tool and by BAN logic.

Purpose: To examine the voice and personality characteristics of patients diagnosed with organic dysphonia secondary to vocal fold immobility. Methods: The study comprised patients of both genders, attending the Clinic School of Speech Therapy of the Federal University of Paraíba, with otorhinolaryngological diagnosis of vocal fold immobility and speech therapy diagnosis of dysphonia. The self-assessment of voice was measured through a Vocal Screening Protocol and Voice Symptoms Scale (VoiSS), the voice was collected for auditory-perceptive evaluation, and the Factorial Personality Battery (FPB) was used. Descriptive statistical analysis was performed to determine the frequency, mean, and standard deviation of the studied variables. Results: Eight patients participated in the study, of both genders, with average age of 40.4±16.9 years. The more frequent risk factors were the personal ones (4.7±2.1). In the VoiSS, the patients presented a higher average in the limitation score (34.1±15.7). From the auditory-perceptive evaluation, moderate intensity of vocal deviation was obtained, with predominant vocal roughness (57.7±25.2). In the FPB, the patients had an average higher than the cutoff scores in neuroticism (3.8±1.4) and accomplishment (5.2±1.0). Conclusion: The predominant vocal parameter was roughness. The patients referred to a few risk factors that compromise the vocal behavior and presented the neuroticism and realization factors as a highlight in their personality. Thus, individuals with vocal fold immobility show personality characteristics that may be a reflection of their voice disorder, not a factor that determines their dysphonia.

AbstractObjectives:A wide range of well validated instruments is now available to assess voice quality and voice-related quality of life, but comparative studies of the responsiveness to change of these measures are lacking. The aim of this study was to assess the responsiveness to change of a range of different measures, following voice therapy and surgery.Design:Longitudinal, cohort comparison study.Setting:Two UK voice clinics.Participants:One hundred and forty-four patients referred for treatment of benign voice disorders, 90 undergoing voice therapy and 54 undergoing laryngeal microsurgery.Main outcome measures:Three measures of self-reported voice quality (the vocal performance questionnaire, the voice handicap index and the voice symptom scale), plus the short form 36 (SF 36) general health status measure and the hospital anxiety and depression score. Perceptual, observer-rated analysis of voice quality was performed using the grade–roughness–breathiness–asthenia–strain scale. We compared the effect sizes (i.e. responsiveness to change) of the principal subscales of all measures before and after voice therapy or phonosurgery.Results:All three self-reported voice measures had large effect sizes following either voice therapy or surgery. Outcomes were similar in both treatment groups. The effect sizes for the observer-rated grade–roughness–breathiness–asthenia–strain scale scores were smaller, although still moderate. The roughness subscale in particular showed little change after therapy or surgery. Only small effects were observed in general health and mood measures.Conclusion:The results suggest that the use of a voice-specific questionnaire is essential for assessing the effectiveness of voice interventions. All three self-reported measures tested were capable of detecting change, and scores were highly correlated. On the basis of this evaluation of different measures' sensitivities to change, there is no strong evidence to favour either the vocal performance questionnaire, the voice handicap index or the voice symptom scale.

A compact textile ultra-wideband (UWB) antenna with an electrical dimension of 0.24λo × 0.24λo × 0.009λo with microstrip line feed at lower edge and a frequency of operation of 2.96 GHz is proposed for UWB application. The analytical investigation using circuit theory concepts and the cavity model of the antenna is presented to validate the design. The main contribution of this paper is to propose a wearable antenna with wide impedance bandwidth of 118.68 % (2.96–11.6 GHz) applicable for UWB range of 3.1 to 10.6 GHz. The results present a maximum gain of 5.47 dBi at 7.3 GHz frequency. Moreover, this antenna exhibits Omni and quasi-Omni radiation patterns at various frequencies (4 GHz, 7 GHz and 10 GHz) for short-distance communication. The cutting notch and slot on the patch, and its effect on the antenna impedance to increase performance through current distribution is also presented. The time-domain characteristic of the proposed antenna is also discussed for the analysis of the pulse distortion phenomena. A constant group delay less than 1 ns is obtained over the entire operating impedance bandwidth (2.96–11.6 GHz) of the textile antenna in both situations, i.e., side by side and front to front. Linear phase consideration is also presented for both situations, as well as configurations of reception and transmission. An assessment of the effects of bending and humidity has been demonstrated by placing the antenna on the human body. The specific absorption rate (SAR) value was tested to show the radiation effect on the human body, and it was found that its impact on the human body SAR value is 1.68 W/kg, which indicates the safer limit to avoid radiation effects. Therefore, the proposed method is promising for telemedicine and mobile health systems.
