This study attempted to provide a spectrum analysis for quantitative evaluation of singing voice quality of singing students rather than the presence or absence of the singer's formant. The regression analysis was used to analyse the relationship between ringing quality, SPR, and SPP of singing voice of college student subjects majoring in music. This study measured singing. power ratio (SPR) in 41 singing students. Digital audio recordings were made in sung vowels for acoustic analyses. Each sample was judged by 1 experienced singing teacher and 4 voice pathologists on one semantic bipolar 7-point scales (ringing-dull). The results showed that the SPR and SPP had significant correlations with ringing quality. The SPR had a significant relationship with ringing quality on singing voice in singing students. The SPR can be an important quantitative measurement for evaluating singing voice quality.

Background and Objectives : Voice therapy has been used as a viable adjuvant to surgery and pharmacological therapy fir the management of voice disorders. The singing voice features a special brand of emotion, intensity, and energy so successful therapeutical approach requires the doctor is able to involve himself into the physical and psychic condition and artistic usage of the voice. The purpose of this study was to evaluate the effect and utility of singing therapy as an initial treatment for classically trained singers with voice disorders. Material and method : Twenty-one male and fifty-five female classic singers with voice disorders were treated with singing therapy. At first, abdominal breathing, resonant phonation, and relaxation method was trained, then after accessing each patient's singing abilities, treatment methods for each specific problems was applied. The results were compared according to age, sex, treatment duration, part, laryngeal pathology, patient subjective evaluation, perceptual evaluation of voice, and maximal phonation time. Results : Patients subjective evaluation, perceptual evaluation, pathologic findings of larynx, maximal phonation time showed superior results after singing therapy. Conclusion : Singing therapy changes the mode of respiration and phonation and enhances the vocal function and improves the laryngeal pathology, The result of this study indicate that singing therapy is an effective treatment method that laryngologists can use for classical singers with voice disorders.

Background and Objectives : Many students major in applied music singing have various difficulties in phonation when they sing or perform. But the studies about this cause are lack. The purpose of this study is whether singing voice therapy based on vocal music is effective or not to applied music singing students that have difficulties in phonation. Materials and Methods : Singing voice therapy program had been done to 8 students major in applied music singing during 7 weeks. We did laryngeal stroboscope, perceptual, acoustic and aerodynamic examination before and after singing voice therapy to this students. And we studied post examination results have differences or improvements compared to pre examination results. Results : Four male students don't have effective improvement after singing voice therapy but they shows slight improvement in aerodynamic examination values compared to pre examination values. Four female students shows improvement in aerodynamic examination values and pitch range increasing. Above all, one student's vocal nodules disappeared after singing voice therapy. Conclusion : Singing voice therapy based on music singing is very effective to the students major in applied music singing. Above all, their curriculum in applied music singing should include phonation training based on music singing before training perform and technic practices.

Most Koreans agree that Korean traditional singing voice has a very peculiar sound comparing to Western singing voice. The goal of this paper is to investigate the acoustic characteristics of Korean traditional singing voice called 'Pansori' Materials are analyzed from 3male professional singers and 4 female professional singers. Their singing was compared with their own conversation and other non-singers' conversation. Long term average spectra indicated that all the singers showed a much less spectral tilt than non-singers. The phenomenon was prevailing for professional singers not only in their singing, but also in their conversation. This suggests that it is not the result of a temporary effort but it may involve a certain permanent change in their physiological configuration. (To assess this hypothesis, voice source should be looked at directly. Therefore, in further research, using Rothenberg mask (Rothenberg, 1973) is strongly recommended.) In addition to LTA, individual vowel formants will be studied later.

The purpose of this study was to investigate the effects of the Bel canto singing technique on voice quality in patients with vocal bowing and sulcus vocalis. Five patients with vocal bowing, and five patients with sulcus vocalis participated in the study. Each subject was assessed acoustically (Jitter, Shimmer, NNE) in the first and last session. Dr. Speech (version 4.0, Tiger-DRS) was used to compare acoustic parameters of pre- and post-treatment. The Bel canto singing technique consisted of breathing exercises, relaxation exercises, and phonation exercises. The results showed that the Bel canto singing technique tended to be effective on improving voice quality in patients with organic voice disorders.

The purpose of this study was to examine changes in acoustic characteristics after drinking alcoholic beverages and singing in order to establish guidelines for vocal hygiene of both singers and non-singers. 21 university students (10 males and 11 females) vocalized /a/ before drinking, after drinking and after singing. Changes in vocal range and acoustic characteristics were analyzed by Dr. Speech 4.0 (Tigers Electronics). No significant difference was observed in vocal range following drinking. However, there was statistically significant changes in vocal range after singing. We may infer that appropriate amount of singing functioning as vocal warm-up, rather than drinking alone, resulted in improvement in their abilities to lengthen vocal folds. This is directly related to the ability to produce high-pitched sounds. Changes in jitter in female voices after singing was the only acoustic factor that was significant. Changes in Shimmer and NNE was not significant either after drinking nor singing. Subjects who were judged to perform better in singing were marked by minimum acoustic changes, which may due to their well-trained vocal fold function. The results of this study may address the necessity for vocal function exercises for the patients with neurogenic voice disorders including dysarthria. The need for more extensive research with a larger number of subjects including professional voice users is also addressed.

Habitual speaking fundamental frequency (sF0) plays an important role in determining the voice classification, which can be presented differently depending on the vocal fold length and language habits. The purpose of this study, therefore, was to compare the differences in sF0 for voice classification and closed quotient between speaking and singing. Seventeen singers (7 sopranos, 5 tenors, 5 baritones, mean age 25.1 years) with no evidence of vocal folds pathology were participated. sF0 and closed quotient (CQ) both in speaking and in singing (A3-A5 with soprano, A2-A4 with tenor and baritone) were measured using SPEAD program and electroglottography. No significant differences were observed for sF0 between tenor and baritone groups (p> 0.05). However, CQ in singing was significantly different among three groups (p< 0.05), but CQ in speaking was not (p> 0.05). Furthermore, CQ was significantly different with both soprano (p< 0.01) and tenor groups ((P= 0.02) whereas baritone group revealed there is no difference when compared between speaking and singing. No significant differences in sF0 between tenor and baritone participants may result from decision-making for voice classification by experience and should measure sF0 before determining the voice classification.

노래음 합성이란 주어진 가사와 악보를 이용하여 컴퓨터에서 노래음을 생성하는 것이다. 텍스트/음성 변환기에 널리 사용된 HMM 기반 음성합성기는 최근 노래음 합성에도 적용되고 있다. 그러나 기존의 구현방법에는 대용량의 노래음 데이터베이스 수집과 학습이 필요하여 구현에 어려움이 있다. 또한 기존의 상용 노래음 합성시스템은 피아노 롤 방식의 악보 표현방식을 사용하고 있어 일반인에게는 익숙하지 않으므로 읽기 쉬운 표준 악보형식의 사용자 인터페이스를 지원하여 노래 학습의 편의성을 향상시킬 필요가 있다. 이 문제를 해결하기 위하여 본 논문에서는 기존 낭독형 음성합성기의 HMM 모델을 이용하고 노래음에 적합한 피치값과 지속시간 제어방법을 적용하여 HMM 모델 파라미터 값을 변화시킴으로서 노래음을 생성하는 방법을 제안한다. 그리고 음표와 가사를 입력하기 위한 MusicXML 기반의 악보편집기를 전단으로, HMM 기반의 텍스트/음성 변환 합성기를 합성기 후단으로서 사용하여 노래음 합성시스템을 구현하는 방법을 제안한다. 본 논문에서 제안하는 방법을 이용하여 합성된 노래음을 평가하였으며 평가결과 활용 가능성을 확인하였다.

The purpose of this study was to determine a correlation between acoustic and perceptual parameters of the singing voice in singing students and compare them with the results with previous studies, and a more sensitive parameters in analyzing professional vocal usage. This study measured acoustic and perceptual parameters in 41 singing students. Digital audio recordings were made in sung vowels acoustic analysis. Each sample was judged by 1 experienced singing teacher and 1 voice pathologist on two semantic bipolar 7-point scales (ringing-dull, rich-thin). The results showed that SPP1 (p<0.01), SPP2 (p<0.01), and P1(p<0.01) had significant correlations with ringing and richness quality.

This article addresses the roles of the speech language pathologist (SLP) for singers who require prompt and effective treatment when a voice problem arises. The causes of voice problem are often vocal abuse/misuse/overuse, muscle tension dysphonia and inappropriate singing technique. The SLP should conduct voice counseling and voice assessment for maintaining healthy voice of singer constantly.
