Physical Modeling of Voice and Voice Quality
نویسنده
چکیده
Physical modeling of the phonatory and vocal tract systems has served as a useful tool to study many aspects of speech production. This paper offers a brief review of two specific types of physically-based models. One for simulating the vibration of the vocal folds and another for representing the vocal tract shape in the form of an area function. While much of the technical detail of these models has been presented elsewhere, the emphasis here will be on providing examples of how physical models may be used for studying voice quality.

Using Context-based Statistical Models to Promote the Quality of Voice Conversion Systems
This article aims to examine methods of optimizing GMM-based voice conversion systems performance in which GMM method is introduced as the basic method for improvement of voice conversion systems performance. In the current methods, due to using a single conversion function to convert all speech units and subsequent spectral smoothing arising from statistical averaging, we will observe quality ...
متن کاملComparing the Voice Handicap Index Scores in Groups with Structural and Functional Voice Disorders
Objective: The effects of voice disorders vary from person to person. Occupation, work environment, life, and family reaction are variables that affect one’s perception of his/her own as an impaired voice. Voice Handicap Index (VHI) has not yet been used to compare the degree of voice disorders. Assuming that the quality of life may be different under a variety of voice disorders and that diffe...
متن کاملDeveloping Fuzzy Models for Estimating the Quality of VoIP
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...

متن کاملEffects of Voice Therapy on Vocal Tract Discomfort in Muscle Tension Dysphonia
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...
