In order to support multimedia applications such as voice and video over the wireless medium, a contentionbased channel access function, called Enhanced Distributed Channel Access (EDCA), has been developed in the emerging standard IEEE 802.11e. In the EDCA, differentiated channel access is provided for different traffic classes. In this paper, we propose a two-level protection and guarantee me...
Wireless telecommunications became over time a ubiquitous tool that not only sustains our increasing need for flexibility and efficiency, but also provides new ways to access and experience both utilitarian and hedonic information goods and services. This paper explores the parallel market evolution of the two main categories of wireless services voice and data in leading technology markets, in...
the present thesis is a study of postmodern historical novel with respect to the voice of women. according to postmodern historiography,the established institution of history is one of the other manifestations of patriarchys power which has silenced women. the study analyzes angela carters nights at the circus as a postmodern historical novel which makes its female characters transgress the pat...
Vibrato is an important factor that affects the naturalness level of a synthetic singing voice. Therefore, the analysis and modeling of vibrato parameters are studied in this paper. The vibrato parameters of those syllables segmented from recorded songs are analyzed by using short-time Fourier transform and the method of analytic signal. After the vibrato parameter values for all training sylla...
Right on voice is one of the rights which protect of person’s voice and sound and prohibit of imitation (sound effects) and sound forgery. Today on the light of increasing developments of communications this right includes some forms and instances which protected by legal systems in different ways. In some of the legal systems, this right has recognized on the basis of personality rights and ri...
In this paper we propose a multifactor hybrid fusion approach for enhancing security in audio-visual speaker verification. Speaker verification experiments conducted on two audiovisual databases, VidTIMIT and UCBN, show that multifactor hybrid fusion involve a combination feature-level fusion of lip-voice features and face-lip-voice features at score-level is indeed a powerful technique for spe...

BACKGROUND Voice problems are more common in teachers due to intensive voice use during routine at work. There is evidence that occupational disphonia prevention programs are important in improving the quality voice and consequently the quality of subjects' lives. AIM To investigate the impact of educational voice interventions for teachers on quality of life and voice. METHODS A longitudin...
Auditory and visual modulation of temporal lobe neurons in voice-sensitive and association cortices.
Effective interactions between conspecific individuals can depend upon the receiver forming a coherent multisensory representation of communication signals, such as merging voice and face content. Neuroimaging studies have identified face- or voice-sensitive areas (Belin et al., 2000; Petkov et al., 2008; Tsao et al., 2008), some of which have been proposed as candidate regions for face and voi...
