Development of a low bit-rate voice over IP application is described. A speech coding algorithm is constructed and implemented on a digital signal processor (DSP). The algorithm is based on a sub-band mixed excitation LPC vocoder structure and operates at a rate of 2000 bits per second. Implementation is done on two TMS320C6701 floating point DSP’s each connected to a PC. On the PC, a graphical...

introduction: bnign laryngeal lesions are relatively commonly occurring problems which are often noted after changes in voice. since they are non-invasive and yield objective easy-to-collect data, acoustic laboratory methods are used along with perceptual assessments for evaluation of voice. studying acoustic characteristics is useful in diagnosis and treatment of voice disorders.  with regard ...

INTRODUCTION This study prospectively evaluates and compares the treatment efficacy of botulinum toxin injection under electromyography guidance (EMG group) and percutaneous botulinum toxin injection under flexible fiberscopic guidance (fiberscopy group). METHODS Thirty patients with adductor spasmodic dysphonia (ADSD), who had never received treatment, were randomly allocated into EMG- or fi...

With an increasing mobility of today’s workforce, organizations have a growing need for information and transactions anytime and anywhere. Mobile network operators (MNO) must therefore meet this need by deploying wireless networks capable of offering advanced voice and data services. While wireless network planning and design has been studied extensively in the literature, most work has focused...

Introduction: Rhinosinus polyposis is associated with voice quality reduction. There has been little evidence about the efficacy of rhinosinus polyps surgery on patients' voice quality so far. The aim of the present study was to evaluate the nasality and acoustic voice changes after rhinosinus polyposis surgery.   Materials and Methods: The population in this study compo...

According to WHO, at any one time, around 50 per cent of medical equipment in lowand middle-income countries cannot be used because of lack of maintenance or spare parts.1 We have found that unwillingness or inability to repair equipment and put it back in use is also a major cause. New equipment is made available by different international non-government organisations (INGOs) competing with on...

researchers are of the belief that employee voice has favorable effects for both the employee and the organization. however, the effect of employee voice on creativity, and the process through which it influences creativity, has hitherto received little attention. this study aimed at investigating the relationship between perceived employee voice and creativity. employees of three premier dairy...

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...
