  1. [해외논문]   The odyssey of Orpheus: The evolution of solo singing  

    Miller, Richard
    Journal of voice : official journal of the Voice Foundation v.10 no.2 ,pp. 109 - 128 , 1996 , 0892-1997 ,

    초록

    Summary Notated sacred solo song dates from 1,000 B.C. Early secular song exhibits modest vocal demands of chant-like character. Popular song and liturgical solo song share common origins. Western European secular song notation began in the early Medieval Age. Compositional writing for solo voice took a dramatic turn toward virtuosity about 1600. By the mid-17th century, the modern solo voice emerged. “Classical” solo vocal literature is not static but is constantly evolving, requiring skills far in excess of those of speech or of early solo song literature; this is equally the case with ethnomusicological and popular singing styles. Efficient use of the singing instrument is essential to the healthy accomplishment of all of these literatures.

  2. [해외논문]   Bifurcations in excised larynx experiments  

    Berry, David A. ; Herzel, Hanspeter ; Titze, Ingo R. ; Story, Brad H.
    Journal of voice : official journal of the Voice Foundation v.10 no.2 ,pp. 129 - 138 , 1996 , 0892-1997 ,

    초록

    Summary Bifurcation analysis was applied to vocal fold vibration in excised larynx experiments. Phonation onset and vocal instabilities were studied in a parameter plane spanned by subglottal pressure and asymmetry of either vocal fold adduction or elongation. Various phonatory regimes were observed, including single vocal fold oscillations. Selected spectra demonstrated correspondence between these regimes and vocal registers noted in the literature. To illustrate the regions spanned by the various phonatory regimes, two-dimensional bifurcation diagrams were generated. Many instabilities or bifurcations were noted in the regions of coexistence, i.e., regions in which the phonatory regimes overlap. Bifurcations were illustrated with spectrograms and fundamental frequency contours. Where possible, results from these studies were related to clinical observations.

  3. [해외논문]   Respiratory and glottal efficiency measures in normal classically trained singers  

    Carroll, Linda M. ; Sataloff, Robert Thayer ; Heuer, Reinhardt J. ; Spiegel, Joseph R. ; Radionoff, Sharon L. ; Cohn, John R.
    Journal of voice : official journal of the Voice Foundation v.10 no.2 ,pp. 139 - 145 , 1996 , 0892-1997 ,

    초록

    Summary Respiratory and glottal efficiency measures were collected from a pool of 40 classically trained singers with normal larynges. All singers had ⩾3 years of formal classical voice training and were active professional solo classical singers. Mean flow rates were obtained from all subjects to assess glottal efficiency. Additionally, maximum phonation times and phonation quotients were obtained from a subset of the singers. Pulmonary function test data on forced expiratory volume, forced vital capacity, and forced expiratory flow were obtained for all subjects. Results were compared with published normal values, not specifically derived from trained singers, used commonly in voice laboratoires. Differences were found, suggesting the need for separate normative data to be used for evaluation of the vocal athlete.

  4. [해외논문]   Objective measures of voice production in patients complaining of laryngeal fatigue  

    Eustace, Carol S. ; Stemple, Joseph C. ; Lee, Linda
    Journal of voice : official journal of the Voice Foundation v.10 no.2 ,pp. 146 - 154 , 1996 , 0892-1997 ,

    초록

    Summary The purpose of this retrospective study is to describe results of acoustic, aerodynamic, and videostroboscopic measures in patients complaining of laryngeal fatigue. Data were collected from 88 patients whose primary complaint was chronic laryngeal fatigue in the absence of visible laryngeal pathologies. The results revealed an abnormally high airflow rate and decreased maximum phonation time. An anterior glottal chink, anterior and posterior glottal chinks, or spindle-shaped glottal closure were found in 61% of the subjects.

  5. [해외논문]   Perceived pitch of whispered vowels-relationship with formant frequencies: A preliminary study  

    Higashikawa, M. ; Nakai, K. ; Sakakura, A. ; Takahashi, H.
    Journal of voice : official journal of the Voice Foundation v.10 no.2 ,pp. 155 - 158 , 1996 , 0892-1997 ,

    초록

    Summary To clarify the role of formant frequency in the perception of pitch in whispering, we conducted a preliminary experiment to determine (1.) whether speakers change their pitch during whispering; (2.) whether listeners can perceive differences in pitch; and (3.) what the acoustical features are when speakers change their pitch. The listening test of whispered Japanese speech demonstrates that one can determine the perceived pitch of vowel /a/ as ordinary, high, or low. Acoustical analysis revealed that the perception of pitch corresponds to some formant frequencies. Further data with synthesized whispered voice are necessary to confirm the importance of the formant frequencies in detail for perceived pitch of whispered vowels.

  6. [해외논문]   Comparison of various automatic means for measuring mean fundamental frequency  

    Morris, Richard J. ; Brown Jr., W.S.
    Journal of voice : official journal of the Voice Foundation v.10 no.2 ,pp. 159 - 165 , 1996 , 0892-1997 ,

    초록

    Summary The purpose of this paper was to evaluate the reliability of, and agreement among, six speech analysis systems in the determination of fundamental frequency. Five male and five female speakers provided oral reading and sustained vowel samples for analysis. Each sample was analyzed five times by each system. The results indicated high reliability for all of the systems for both sexes and both utterance types. Agreement among the systems was high for the male sustained vowels and the female oral reading samples. In contrast, poor agreement occurred among the systems for the male oral reading samples and the female sustained vowels. The findings indicate that the output of these automatic methods tends to be consistent over repeated trials within the systems in their extraction of fundamental frequency; however, agreement among these systems varies.

  7. [해외논문]   Intrasubject variability of objective voice measures  

    Bough Jr., I. David ; Heuer Jr., Reinhardt J. ; Sataloff Jr., Robert Thayer ; Hills Jr., James R. ; Cater Jr., Jacqueline R.
    Journal of voice : official journal of the Voice Foundation v.10 no.2 ,pp. 166 - 174 , 1996 , 0892-1997 ,

    초록

    Summary Recent advances in the diagnosis and treatment of voice disorders necessitate the need for accurate and reliable objective voice measurements. There are many instruments commonly used to analyze voice data. Many, if not most, of these instruments have not been adequately tested for reliability or consistency. This study evaluates the intrasubject variability of the objective voice measurements from two commonly used voice analysis instruments. The study also presents data correlating subjective mood states, room temperatures, sleep times of the subject, time since last meal, and hydration levels to the various acoustic measures. Several weak but significant correlations were obtained and are discussed. Guidelines for the appropriate use of these instruments are described.

  8. [해외논문]   Standardized laryngeal videostroboscopic rating: Differences between untrained and trained male and female subjects, and effects of varying sound intensity, fundamental frequency, and age  

    Sulter, Arend M. ; Schutte, Harm K. ; Miller, Donald G.
    Journal of voice : official journal of the Voice Foundation v.10 no.2 ,pp. 175 - 189 , 1996 , 0892-1997 ,

    초록

    Summary To determine the influence of the factors gender, vocal training, sound intensity, pitch, and aging on vocal function, videolaryngostroboscopic images of 214 subjects, subdivided according to gender and status of vocal training, were evaluated by three judges with standardized rating scales, comprising aspects of laryngeal appearance (larynx/pharynx ratio; epiglottal shape; asymmetry arytenoid region; compensatory adjustments; thickness, width, length, and elasticity of vocal folds) and glottal functioning (amplitudes of excursion; duration, percentage, and type of vocal fold closure; phase differences; location of glottal chink). The video registrations were made while the subjects performed a set of phonatory tasks, comprising the utterance of the vowel /i/ at three levels of both fundamental frequency and sound intensity. Analysis of the rating scales showed generally sufficient agreement among judges. With the exception of more frequently observed complete closure and lateral phase differences of vocal fold excursions in trained subjects, no further differences were established between untrained and trained subjects. With an α level of p = 0.005, men differed from women with respect to laryngeal appearance (larynx/pharynx ratio, compensatory adjustments, and the presence of omega and deviant-shaped epiglottises), and their vocal folds were rated thicker in the vertical dimension, smaller in the lateral dimension, longer, and more tense, with smaller amplitudes of excursion during vibration. Glottal closure in male subjects was rated more complete, but briefer in duration. Significant effects of the factors pitch, sound intensity, and age on vocal fold appearance and glottal functioning were ascertained. Awareness of the influence of these factors, as well as the factor gender, on the rated scales is essential for an adequate evaluation of laryngostroboscopic images.

  9. [해외논문]   The sound of senescence  

    Linville, Sue Ellen
    Journal of voice : official journal of the Voice Foundation v.10 no.2 ,pp. 190 - 200 , 1996 , 0892-1997 ,

    초록

    Summary This paper draws together findings of recent studies examining changes in voice with aging. Listeners' accuracy in perceiving age from voice is discussed, along with changes in speaking fundamental frequency, fundamental frequency stability, temporal aspects of speech, and resonance features of voice with aging. Descriptions are provided of differences in glottal gap configuration as a function of age and gender. In addition, acoustic/temporal measures that have been demonstrated to correlate with perceived age estimates are presented.

  10. [해외논문]   Videokymography: High-speed line scanning of vocal fold vibration  

    Švec, Jan G. ; Schutte, Harm K.
    Journal of voice : official journal of the Voice Foundation v.10 no.2 ,pp. 201 - 205 , 1996 , 0892-1997 ,

    초록

    Summary A digital technique for high-speed visualization of vibration, called videokymography, was developed and applied to the vocal folds. The system uses a modified video camera able to work in two modes: high-speed (nearly 8,000 images/s) and standard (50 images/s in CCIR norm). In the high-speed mode, the camera selects one active horizontal line (transverse to the glottis) from the whole laryngeal image. The successive line images are presented in real time on a commercial TV monitor, filling each video frame from top to bottom. The system makes it possible to observe left-right asymmetries, open quotient, propagation of mucosal waves, movement of the upper and, in the closing phase, the lower margins of the vocal folds, etc. The technique is suitable for further processing and quantification of recorded vibration.
