Introduction: Use of patient-based voice assessment scales is an appropriate method that is frequently used to demonstrate effectiveness of voice therapy. This study was aimed at determining the effectiveness ofvoice therapy among patients with secondary muscle tension dysphonia (MTD) and vocal mass lesions.   Materials and Methods: The study design was prospective, with within-participant repe...

Objectives: The present study aimed to determine the voice outcomes before and after the administration of voice therapy in patients who suffered an injury to the recurrent laryngeal nerve after undergoing thyroidectomy. Methods: The sample consisted of 26 patients (2 males and 24 females) aged between 18 and 80 years (m=55±12) who experienced injury to the recurrent laryngeal nerve fol...

BACKGROUND Voice recognition systems (VRS) allow speech to be converted both directly into text-which appears on the screen of a computer-and to direct equipment to perform specific functions. Suggested applications are many and varied, including increasing efficiency in the reporting of radiographs, allowing directed surgery and enabling individuals with upper limb disorders (ULDs) who cannot ...

Traditionally the interest in voice gender conversion was of a more theoretical nature rather than founded in real–life applications. However, with the increase in mobile communication and the resulting limitation in transmission bandwidth new approaches to minimising data rates have to be developed. Here voice gender normalisation (VGN) presents an efficient method of achieving higher compress...

A ubiquitous networked society, in which all electronic equipment including “sensors” are connected to a network and are able to communicate with one another to share information, will shortly become a reality. Although sensor information is most important in such a network, it does include a large amount of privacy information and therefore it is preferable not to send raw information across t...

In the field of mobile communications correct Voice Activity Detection (VAD) is a crucial point for the perceived speech quality, the reduction of co-channel interference, the power consumption in portable equipment. This paper shows that a valid alternative to deal with the problem of activity decision is to use methodologies like fuzzy logic, which are suitable for problems requiring approxim...

In this study, six patients who were judged to produce speech with excessive laryngeal tension participated in 14 30-min biofeedback training sessions. The EMG signal, measured by bipolar surface electrodes placed over the cricothyroid region, was amplified, integrated, and used to control the output of a voltage controlled oscillator (VCO) and a noise generator. A voltage comparator was used a...

and Section 6-8: Together ii Abstract Voice over IP over Wireless LAN (VoWLAN) is getting great attention from the industry and the products for VoWLAN deployment are emerging rapidly. Although technologies for carrying voice in IP networks have been advancing for years, carrying voice over wireless networks introduces new challenges. For end users, the performance of VoWLAN phones (802.11 phon...

The ARX-LF model interprets voiced speech as the an LF derivative glottal pulse exciting an all-pole vocal tract filter with an additional exogenous residual signal. It fully parameterizes the voice and has been shown to be useful for voice modification. Because time domain methods to determine the ARX-LF parameters from speech are very sensitive to the time placement of the analysis frame and ...

Xcell Journal Third Quarter 2011 Traditional telecom networks are fundamentally configured to transport voice, such as phone service. Internet services piggyback on this legacy platform. Currently, designers are creating the next-generation network (NGN) to transport data, voice and video simultaneously, providing transparency and scalability while minimizing total operational cost. The NGN is ...
