Work on voice sciences over recent decades has led to a proliferation of acoustic parameters that are used quite selectively and not always extracted in similar fashion. With many independent teams working different research areas, shared standards become an essential safeguard ensure compliance with state-of-the-art methods allowing appropriate comparison results across studies potential integration combination extraction recognition systems. In this paper we propose basic standard...
An articulatory model is presented. It defines a procedure for deriving set of formant frequencies from information on the state lip muscles, position jaw, shape and tongue body, larynx height. The acoustic auditory consequences varying these parameters individually are reported. introduction jaw as separate parameter—a feature not used in previous models—makes it possible to explain why “openness” occurs universal phonetic vowel production. According explanation proposed, degree opening...
The “singing formant” is a high spectrum envelope peak near 2.8 kHz characteristic of vowel sounds produced in male Western opera and concert singing. An acoustical model the vocal tract capable generating such provided that three conditions are met: (1) cross-sectional area pharynx must be at least six times wider than larynx tube opening. If so, acoustically mismatched with rest tract, an extra formant added to transfer function. (2) sinus Morgagni wide relation tube. This may tune...
AbstractA set of 17 voices representing various voice disorders were presented to a jury experts who rated them on 5-point scale for each 28 terms frequently used describing voices. A statistical treatment these ratings yielded 5 bipolar factors accounting 85% the total variance. Significant correlations found between four and certain acoustic data extracted from long-time-average spectra fundamental frequency distribution analysis same sample.

In acoustic communication timing seems to be an exceedingly important aspect. The just noticeable difference (jnd) for small perturbations of isochronous sequence sounds is particularly in music, which such sequences frequently occur. This article reviews the literature area and presents experiment designed resolve some conflicting results regarding tempo dependence quick tempi relevance music experience. jnd a perturbation tone appearing was examined by method adjustment. Thirty listeners...
Vocal intensity is studied as a function of fundamental frequency and lung pressure. A combination analytical empirical models used to predict sound pressure levels from glottal waveforms five professional tenors twenty normal control subjects. The were obtained by inverse filtering the mouth flow. Empirical describe features flow waveform (peak flow, peak derivative, open quotient, speed quotient) in terms phonation threshold pressure, key variable that incorporates F0 dependence many model...

This investigation explores the common assumption that music and motion are closely related by comparing stopping of running termination a piece music. Video recordings were made professional dancers’ from under different deceleration conditions, instant values body velocity, step frequency, length estimated. In decelerations highly rated for aesthetic quality panel choreographers, mean velocity could be approximated square-root function time, which is equivalent to cubic-root position....

Emotions have strong effects on the voice production mechanisms and consequently characteristics. The magnitude of these effects, measured using source parameters, interdependencies among parameters not been examined. To better understand relationships, characteristics were analyzed in 10 actors' productions a sustained/a/vowel five emotions. Twelve acoustic studied grouped according to their physiological backgrounds, three related subglottal pressure, transglottal airflow waveform derived...
Resonance tube phonation in water (RTPW) or air is a voice therapy method successfully used for treatment of several pathologies. Its effect on the has not been thoroughly studied. This investigation analyzes effects RTPW collision and threshold pressures (CTP PTP), lowest subglottal pressure needed vocal fold phonation, respectively.Twelve mezzo-sopranos phonated into glass tube, end which was placed under surface jar. Subglottal pressure, electroglottography, audio signals were recorded...

Long-term-average spectrum (LTAS) is an efficient method for voice analysis, revealing both source and formant characteristics. However, the LTAS contour non-uniformly affected by vocal loudness. This variation was analyzed in 15 male 16 female untrained voices reading a text 7 times at different degrees of loudness, mean change overall equivalent sound level (Leq) amounting to 27.9 dB 28.4 subjects. For all frequency values up 4 kHz, strongly linearly correlated with Leq each subject. The...
