This paper outlines a strategy for exploring the paralinguistic signalling of emotion, mood and attitude. The focus here is on the role of voice quality and the approach adopted involves three distinct phases. The first involves detailed acoustic analyses of a range of voice qualities. The second involves the resynthesis and perceptual testing of individual voice qualities. The third stage, and...

Change in voice quality (VQ) is one of the first precursors of Parkinson’s disease (PD). Specifically, impacted phonation and articulation causes the patient to have a breathy, husky-semiwhisper and hoarse voice. A goal of this paper is to characterize a VQ spectrum – the composition of non-modal phonations – of voice in PD. The paper relates non-modal healthy phonations: breathy, creaky, tense...

BACKGROUND This cross-sectional study objects to measure, subjectively and objectively, the voice and life quality of patients with oral cavity, pharyngeal and laryngeal cancer, after organ-preservation treatment. METHODS 25 cases diagnosed and treated at a high complexity oncology center in southeastern Brazil. All had oral cavity, pharyngeal or laryngeal cancer, with a therapeutic proposal ...

The “EOIP; Every Thing Over IP“ networks are widely replacing today’s different pillar networks in to the single converged network for Telephony(Any type of Access i.e. Mobile or Fixed Line) and data. Definitely new services will be expected in the NGN / EOIP such as broadcast media transmission and video on demand. But one major issues are always from past so many years are associated with Int...

Voice over Internet Protocol is a technology of transmitting voice on the Internet. Human voice is digitized, encoded, and transmitted on the Internet in the form of voice packets. These packets are received at the other end, decoded and converted back to analog signal. Loss and delay of voice packets result in the degradation of voice quality, since voice is a real-time application. Consecutiv...

BACKGROUND Voice disorders resulting from glottic insufficiency are a significant clinical problem in everyday phoniatric practice. One method of treatment is injection laryngoplasty. Our study aimed to assess the voice quality of patients treated with hyaluronic acid injection into the vocal fold. MATERIAL AND METHODS We studied 25 patients suffering from dysphonia, conducting laryngological...

In this paper, we identify some impairments in the Voice over Internet Protocol (VoIP) networks and quantify the levels of voice quality. We propose an optimization model to maximize number of calls in low speed network for Rural Next Generation Network (R-NGN) while maintaining a minimum level of voice quality. The model is based-on Extended E-model to select parameters like voice coder, packe...

Modeling natural sounding voice qualities – for example the pressed-modalbreathy voice quality continuum which widely occurs during normal speech production – is a crucial point in speech synthesis. A parametric voice source model using prescribed sinusoidal vocal fold vibration patterns (i.e. extended Titze model) is introduced in this paper. This voice source model was adapted for synthesis o...

This paper derived four acoustic parameters reflecting voice quality improvement by voice training. Voice training corrects respiration, phonation, articulation, and facial expression. The purpose of this study is to develop acoustic parameters which quantitatively represent the quality of each training item. This paper examined six acoustical feature parameters on the performance as the measur...

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 ...
