This paper presents a novel method for modeling the one-way quality prediction of VoIP, non-intrusively. Intrusive measures of voice quality suffer from common deficiency that is the need of reference signal for evaluating the quality of voice. Owing to this lack, a great deal of effort has been recently devoted for modeling voice quality prediction non-intrusively according to quality degradat...
Objective Today transoral laser microsurgery is considered as one of the first options to control early laryngeal cancer, and voice disorder is one of the inevitable complications of this therapeutic component. This study aimed to compare the vocal function in patients with early-stage laryngeal cancer following laser surgery with healthy individuals with normal voice quality using acoustic ana...
Objectives: “Voice” is affected more and sooner than other speech subsystems in Parkinson's Disease (PD). Voice Handicap Index (VHI) is the most applicable subjective self-rating questionnaire in VD patients. The aim of this study was the investigation of Voice handicap in Iranian PD patients. Methods & Materials: This cross-sectional, analytical and non-interventional study was ...
Background and Objective: In health system using patient-based tools to measure life quality is a source of making clinical decision. The voice of individuals with hearing loss faces have some problems because of getting inappropriate feedback. According to multilateral impacts on life quality, it is necessary to study the relationship between public life quality (SF 36) and voice-related life ...
background: one third of patients with parkinson’s disease (pd) have mentioned “dysphonia” as their most debilitating communication deficit. patient-based measurements, such as voice handicap index (vhi) add necessary supplementary information to clinical and physiological assessment. there are a few studies about relation between vhi and disease severity in pd, although none of them showed any...
Reports indicate that one of the causes of harmful to the genital system, especially the testes is stress. Result of damage to testicular quality certainly will affect the quality of sperm fertility. Stress could be created secondarily after some pathological conditions such as neurological diseases or environmental factors. One of the causes of stress could be scary voices, such as cat voice f...
Background: Since in multiple sclerosis (MS), changes in speech and voice quality often precede other signs and symptoms; early diagnosis of these changes is necessary. In this study, an acoustic examination of phonation subsystem was performed. Due to the progressive nature of multiple sclerosis, the aim of this study was to examine the correlation between acoustic parameters ...
backround laryngopharyngeal reflux (lpr) is the backflow of stomach contents above upper esophageal sphincter, into the pharynx, larynx, and upper aerodigestive system. objectives in this study, effects of omeprazole over voice quality in muscle tension dysphonia with laryngopharyngeal reflux was ınvestigated. patients and methods nine patients, 7 males and 2 females, aged between 27-43 (mean a...
Introduction: The art of voice mimicking by computers, has with the computer have been one of the most challenging topics of speech processing in recent years. The system of voice conversion has two sides. In one side, the speaker is the source that his or her voice has been changed for mimicking the target speaker’s voice (which is on the other side). Two methods of p...
in a voice conversion system speech signal of a speaker (i.e. source speaker) is modified so that it sounds as if it had been pronounced by b speaker (i.e. target speaker). this process, sometimes, is called speaker conversion (changing speaker identity). achieved signal from speaker conversion system is desired to have high quality and very natural. to satisfy this, three major methods are pro...
