Pop singers frequently use breathy voice to express diverse emotion. Such method is the major factor that divides vocalization in pop and classical music. Using breathy voice too much for a long time could make singer short-winded, which might cause the voice injured. In order to prevent the problem, singers need to find resonance balance between high notes and low notes and among vowels. Moreover, they should take more attention when producing resonance in consonants with much air flow. Along with finding resonance balance, if skilled at controlling the volume of voice, singers can use the breathy voice selectively at the desired part, adjusting close quotient freely. Through this kind of approach, pop singers can develope their unique style of vocalization and avoid the vocal damage.

Functional dysphonia is a specific voice disorder refers to dysphonia without abnormal anatomical vocal fold findings at larynx. The proportions of this disorder are estimated up to 40% of dysphonia patients at ENT clinics. In this article, we will discuss about other functional dysphonia and neurological dysphonia except for muslce tension dysphonia and spasmodic dysphonia. For details, will describe about phonatory charateristics and treatment options about paradoxical vocal fold motion disorder, mutational dysphonia, essential vocal tremor, conversion dysphonia, and vocal tremor related with parkinson's disease.

Spasmodic dysphonia (SD) is a chronic, focal, speech-induced, action-specific dystonia, resulting strained voice. Muscle tension dysphonia (MTD) may also result in a strangled, strained voice quality, usually as a result of compensation for underlying laryngeal disease such as glottal insufficiency. Patients with SD and MTD were suffered from the severely limiting people's communication, especially via telephone and in noisy backgrounds. SD is usually of the adductor type characterized by glottic contractions causing tightness and voice breaks, which is difficult to distinguish from MTD. In this review article, we present the characteritics and management of SD and MTD.

배경 : 전문 음성 사용자(professional voice user)중 성악인들은 특히 음성문제에 관심이 많으며, 전문 성악인이나 성악전공학생들은 항상 가장 좋은 발성으로 아름다운 연주를 하기 위해 노력한다(이정희 1992 ; 황화자 1999 ; Appleman 1986). 목적 : 병변이 없는 정상 성악인과 병변이 있는 성악인의 경우, 음성언어치료사가 행할 수 있는 치료접근법을 알아보고자 한다. (중략)

Tube phonation in water has been widely used for voice training among semi-occluded vocal tract (SOVT) exercises in which the patient bubbles with phonation keeping the tube submerged in water. This study aims to investigate the effect of tube diameter and water depth on bubble height and maximum phonation time (MPT) for patients with hyperfunctional voice disorders. Seventeen patients with hyperfunctional voice disorders were asked to bubble with sustained /u/ at the different inner diameters of tube (5, 7, and 10 mm), water depth (4, 7, and 10 cm). A water resistance phonation biofeedback system using a water height sensor was used for recording bubble height and MPT. The bubble height was significantly changed by the tube diameter while MPT was significantly changed with the tube diameter and water depth. Although the wider tube presented significantly lower bubble height for a given depth, relatively consistent bubble height was maintained. Depending on the water depth, the bubble height did not significantly differ for a given tube diameter. In addtion, MPT significantly decreased with water depth and a wider tube led significantly shorter MPT. A water level-driven water resistance biofeedback system provided useful information on bubble characteristics and vocal fold vibration depending on tube diameter and water depth. It can be useful to monitor the breath support during water resistance phonation for patients with hyperfunctional voice disorders.

사람의 발성 기관은 공기를 짜내어 주는 역할을 하는 호흡기관(breathing apparatus)과 소리의 원음을 만들어 내는 성대(vocal folds) 그리고 성대로부터 만들어진 원음을 공명 (resonance) 시키고 여과(filtering) 시킴으로써 특징적인 소리의 모양을 갖추는 역할을 하는 성도(vocal tract)로 크게 나누어 볼 수 있다.
