communication disorder is a widespread disabling problems and associated with adverse, long term outcome that impact on individuals, families and academic achievement of children in the school years and affect vocational choices later in adulthood. the aim of this study was to determine prevalence of speech disorders specifically stuttering, voice, and speech-sound disorders in primary school s...

Nowadays, Identification and Classification of voice pathology plays a major role in the field of speech processing. This paper explores and compares various things like input database, parameters, features extraction techniques, methodology and classification techniques used by the researchers in the problem of identifying the voice pathology. In this paper, we compared seven research works do...

BACKGROUND Up to 80% of patients without a recurrent laryngeal nerve palsy report alteration in their voice after a thyroid procedure. The aims of this study were (1) to quantify voice changes after thyroid operation; (2) to correlate the changes to the extent of operation; and (3) to correlate voice changes to intraoperative recurrent laryngeal nerve swelling. METHODS Patients undergoing tot...

Changes in speech have been suggested as sensitive and valid measures of depression and mania in bipolar disorder. The present study aimed at investigating (1) voice features collected during phone calls as objective markers of affective states in bipolar disorder and (2) if combining voice features with automatically generated objective smartphone data on behavioral activities (for example, nu...

Most previous studies on acoustic assessment of disordered voice were focused on extracting perturbation features from isolated vowels produced with steady-state phonation. Natural speech, however, is considered to be more preferable in the aspects of flexibility, effectiveness and reliability for clinical practice. This paper presents an investigation on applying automatic speech recognition (...

Children with voice disorders do respond to treatment, with vocal hyperfunction being the predominant disorder on the caseload of the pediatric voice clinician. This article reviews the literature in describing what is known about these children and typical disorders, prevention of voice disorders, the need for treatment, the referral patterns of teachers and others, and typical management prog...

OBJECTIVES/HYPOTHESIS Adductor spasmodic dysphonia (AdSD) is a voice disorder characterized by variable symptom severity and voice disability. Those with the disorder experience a wide spectrum of symptom severity over time, resulting in varied degrees of perceived voice disability. This study investigated the longitudinal variability of AdSD, with a focus on auditory-perceptual judgments of a ...

Many speech features and models, including Deep Neural Networks (DNN), are used for classification tasks between healthy pathological with the Saarbruecken Voice Database (SVD). However, accuracy values of 80.71% phrases or 82.8% vowels /aiu/ highest reported audio samples in SVD when evaluation includes wide amount pathologies database, instead a selection some pathologies. This paper targets ...

Spasmodic dysphonia (SD) is a voice disorder characterized by abnormal intermittent spasms of intralaryngeal muscles that result in voice breaks during speech. In the adductor variant of spasmodic dysphonia (ADSD), spasms of the adductor muscles cause strangled voice breaks and a strained-strangled voice quality. In the abductor variant (ABSD), spasms of the posterior cricoarytenoid muscle (PCA...
