The increasing range 01 applications 01 local area networks (LAN) reflects their importance in todays inhouse communication. The requirements in office scenarios to support both, voice and data connections, locus the point 01 view to LAN systems, which are capable 01 integrating these different traffic streams. Recently, various LAN access schemes including voice communications have been develo...

A modified two-mass model of the vocal folds is introduced and applied to the articulatory synthesis of words in six voice qualities. The modified two-mass model uses mass elements that are inclined, instead of parallel, with respect to the dorsoventral axis as a function of the degree of abduction. This allows to produce the continuum of voice qualities from pressed over modal to breathy voice...

Teachers often suffer from health problems related to their voice. These problems are related to their working environment, including the acoustics of the lecture rooms. However, there is a lack of studies linking the room acoustic parameters to the voice produced by the speaker. In this pilot study, the main goals are to investigate whether objectively measurable parameters of the rooms can be...

BACKGROUND overall voice and strain level analysis in rock singers. AIM to analyze the voice o rock singers according to two specific parameters: overall level of vocal deviation (OLVD) and strain level (SL); to compare these parameters in three different music samples. METHOD participants were 26 male rock singers, ranging in age from 17 to 46 years (mean = 29.8 years). All of the particip...

This paper presents a voice-activity detection (VAD) method for sound sequences with various SNRs. For real-time VAD applications, it is inadequate to employ a post-processing for the removal of burst clippings from the VAD output decision. To tackle this problem, building on the bilevel hidden Markov model, for which a state layer is inserted into a typical hidden Markov model (HMM), we formul...

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...

OBJECTIVES This study aimed (1) to investigate music theory teachers' professional and extra-professional vocal loading and background noise exposure, (2) to determine the correlation between vocal loading and background noise, and (3) to determine the correlation between vocal loading and self-evaluation data. METHODS Using voice dosimetry, 13 music theory teachers were monitored for one wor...

OBJECTIVES/HYPOTHESIS To analyze tracheoesophageal voice resistance in laryngectomized patients by comparing the acoustic, perceptive-auditory and self-evaluation measures before and after the voice resistance test. STUDY DESIGN An observational, experimental study with a quantitative and descriptive approach. METHODS Nineteen total laryngectomees were submitted for capture of vocal intensi...

Speech processing related changes in the speech spectra may often lead to unwanted changes in the effective degree of voicing, which in turn may degrade the speech quality. This phenomenon is studied more closely in this paper, first on a theoretical level and then in the context of voice conversion. Moreover, a simple but efficient approach for avoiding the unwanted changes in the effective le...
