This paper investigates the effectiveness of measures related to vocal tract characteristics in classifying normal and pathological speech. Unlike conventional approaches that mainly focus on features related to the vocal source, vocal tract characteristics are examined to determine if interaction effects between vocal folds and the vocal tract can be used to detect pathological speech. Especia...

Periodic waves in the modified Korteweg–de Vries (mKdV) equation are revisited setting of fractional Laplacian. Two families solutions local case given by sign-definite dnoidal and sign-indefinite cnoidal solutions. Both can be characterized general as global minimizers quadratic part energy functional subject to fixed \(L^4\) norm: (sign-indefinite) obtained subspace even (odd) functions. Mors...

objectives: nasality is one of the important parameters in pathology of voice resonance. voice of normal adults has nasality to some extent. it appears that nasality, like other parameters of voice, can be affected by loudness which can be measured in experimental evaluations. this study was conducted to determine the effect of vocal loudness on nasalance of vowels in normal adults and to ident...

introduction:tapia’s syndrome is a rare complication of recurrent laryngeal and hypoglossal nerve paralysis due to anesthetic airway mismanagement or malpositioning of the patient’s head during surgery. case report:here we present a case of tapia's syndrome in a 22-year-old male after corrective jaw surgery under general anesthesia, with a long period of recovery, related to airway managem...

Wikström's Situational Action Theory (SAT) explains rule-breaking by reference to the cognitive perception-choice process, which indicates how a person's propensity break rules interacts with setting's criminogeneity. SAT's situational model claims that interaction between personal morality and moral norms of setting, so-called filter, is critical in explanation rule-breaking, influence self-co...

Purpose: To investigate whether there is an association between the frequency of occurrence of vocal symptoms, the intensity of vocal deviation and laryngeal diagnosis in patients with different voice disorders. Methods: The study included 330 patients with vocal complaints. The patients were divided into five groups according to the laryngeal diagnosis: G1without laryngeal lesions; G2 -benign ...

Introduction: Patients with muscle tension dysphonia (MTD) suffer from several physical discomforts in their vocal tract. However, few studies have examined the effects of voice therapy (VT) on the vocal tract discomfort (VTD) in patients with voice disorders. Therefore, the aim of the present study was to investigate the effects of VT on the VTD in patients with MTD.   Materi...

Learned vocalization, the substrate for human language, is a rare trait. It is found in three distantly related groups of birds-parrots, hummingbirds, and songbirds. These three groups contain cerebral vocal nuclei for learned vocalization not found in their more closely related vocal nonlearning relatives. Here, we cloned 21 receptor subunits/subtypes of all four glutamate receptor families (A...

Objective: Explore the practical clinical significance and correlation of voice handicap index (VHI) for vocal polyps and vocal nodules, and further validate practicality of VHI. Methods: VHI of vocal cord polyp group (n = 35), vocal nodule group (n = 29), and control group (n = 22) was surveyed respectively. The VHI investigation included three categories of function (F), physiology (P) and em...

Wave height as well as water depth at the breaking point are two basic parameters which are necessary for studying coastal processes. In this study, the application of soft computing-based methods such as artificial neural network (ANN), fuzzy inference system (FIS), adaptive neuro fuzzy inference system (ANFIS) and semi-empirical models for prediction of these parameters are investigated. Th...
