  • Electroglottography (EGG) is a simple and non-invasive technique for analyzing the vibratory patterns of the vocal folds by detecting impedance changes across the larynx. An abnormal electroglottogram is shown in patients who have a dysphagia associated with neuromuscular disorder. Electroglottography offers reliable informations for diagnosis of swallowing disorder and gives quantitative datas. The purpose of this study is to provide the normal value of electroglottography in normal adults. We took electroglottograms of 80 adults who have no problem in swallowing and utterance. EGG data were analyzed to find out the value of Pitch, Jitter and Closed quotient with a commercially available software. There were significant differences between a usual voice and loud voice in 3 measures on the EGG signalmean pitch, Avg. jitter, mean quotient. To get a proper electroglottography, phonation of a usual voice was better than a loud voice. Four measurements- S.D pitch, Avg. Jitter, Mean closed quotient, S.D closed quotient- were independent of sex for adult. Three measurements- Mean pitch, S.D pitch, Mean closed quotient - were independent of age for adult aged twenties to fifties. The Avg. Jitter of twenties appeared to be lower than those of forties and fifties. The S.D closed quotient of twenties appeared to be lower than those of thirties, forties and fifties.

  • The purpose of this study was to compare professional (Pro) and non-professional (Non-pro) voice users with voice disorders in self-reporting voice evaluation using Korean-Voice Handicap Index (K-VHI) and Korean-Voice Related Quality of Life (K-VRQOL). In addition, those were compared by voice quality and voice disorder type. 94 Pro and 106 Non-pro were asked to fill out the K-VHI and K-VRQOL, perceptually evaluated on GRBAS scales, and divided into three types of voice disorders (functional, organic and neurologic) by an experienced speech-language pathologist and an otolaryngologist. The results showed that the functional (F) and physical (P) scores of K-VHI in Pro group were significantly higher than those in Non-pro group. As the voice quality evaluated by G scale got worse, the scores of all aspects except emotional (E) of K-VHI and social-emotional (SE) of K-VRQOL were higher. All scores of K-VHI and K-VRQOL in neurologic voice disorders were significantly higher than those in functional and organic voice disorders. In conclusion, professional voice users are more sensitive to their functional and physical handicap resulted by their voice problems and that goes double for the patients with severe and neurologic voice disorders.

  • Studies on the risk factors of voice disorders in Korean adults are rare. I evaluated the association between the duration of self-reported voice problem and voice disorders in Korean adults. Data were from the 2008 Korea National Health and Nutritional Examination Survey. Subjects were 3,135 people (1,310 men and 1,825 women) aged 19 years and older. Multi-nominal logistic regression analyses were used to examine the association between the duration of self-reported voice problem and voice disorders. The prevalence of self-reported voice problems was 5.9% among Korean adults. Adjusting for covariates (age, sex, education level, length of employment, tobacco consumption, alcohol consumption, thyroid disorders, pain and discomfort during the last two weeks), self-reported voice problems lasting longer than three weeks were independently associated with functional voice disorders (OR=5.30, 95% CI: 3.30-8.50) and organic voice disorders (OR=4.84, 95% CI: 1.82-12.89). Self-reported voice problems in the past three weeks were significantly associated with functional voice disorders (OR=3.64, 95% CI: 1.84-7.19), but not significantly associated with organic voice disorders. Self-reported voice problems are prevalent among adults. This study highlights that self-perception of a voice problem for more than three weeks is related to functional voice disorders and organic voice disorders.

  • This study was conducted to identify the characteristics of pauses and breath groups made by normal adults and patients with voice disorders while reading a paragraph. Forty normal female adults and forty female patients with a functional voice disorder (18-45 yrs.) read the "Gaeul" paragraph with the "Running Speech" protocol of the Phonatory Aerodynamic System (PAS), by which the pauses with or without inspiration and between or within syntactic words and breath groups were analyzed. The number of pauses with inspiration was found to be higher in the patient group, but the number of pauses without inspiration was higher in the normal group. The rate of syntactic word boundaries with pauses with inspiration was higher in the patient group, while the number of syllables per breath group was higher in the normal group. As these results can be explained by patients' poor breath support due to glottal insufficiency, the question of whether voice disorder patients use their pauses and breath groups properly should be considered carefully in evaluation and intervention.

  • In this paper, we design and implement complement based speech training system for voice disorder. The system consists of three level of training: precedent training, training for speech apprehension and training for speech enhancement. To analyze speech of voice disorder, we extracted speech features as loudness, amplitude, pitch using digital signal processing technique. Extracted features are converted to graphic interface for visual feedback of speech by the system.

  • The purpose of this study was to investigate vocal hygiene habits and Korean Voice-Related Quality of Life (K-VRQOL) among classical singers. A total of 128 classical singers filled an online voice and K-VRQOL questionnaire, and the results were analyzed. In order to investigate the characteristics of K-VRQOL according to age groups, and the presence or absence of a history of voice problems, we conducted a two-way ANOVA. The results are as follows. Of the 128 classical singers, 28 (21.9%) with a history of voice problems said that excessive conversation, singing practice, and yelling were the causes of their voice problems. The symptoms of voice problems were fatigue, loss of range, hoarseness, and breathiness. In addition, classical singers were less likely to smoke, or to drink alcohol or caffeine. The K-VRQOL was highly correlated with all sub-domains. There was a statistically significant difference according to age groups (p<.05) and history of voice problems (p<.01). There was no correlation between age groups and history of voice problems. Voice management is important because classical singers can ruin their voice by speaking, and the risk of voice disorder is high. Voice problems affect quality of life. In future studies, it is necessary to obtain information on the subjective voice characteristics of classical singers by examining the relationship between their voice hygiene habits and VHI, SVHI, and K-VRQOL.

  • In this paper, we synthesized vowel /ae/ with voice synthesis program of Dr. Speech Science, and we also synthesized pathologic vowel /ae/ by some parameters such as high frequency gain (HFG), low frequency gain(LFG), pitch flutter(PF) which represents jitter value and flutter of amplitude(FA) which represents shimmer value, and grade ranked as mild, moderate and severe respectively. And then we analysed all pathologic voice by analysis program of Dr. Speech Science. We expect that this synthesized pathologic voices are useful for understanding the parameter such as noise, jitter and shimmer and feedback effect to patient with voice disorder.

  • Functional dysphonia (FD) is a voice disorder in the absence of structural or neurologic laryngeal pathology. FD is not a single disease but a disease entity. Therefore several voice disorders, which have completely different pathogenesis, are included in this category. The first step of treatment of FD is differentiating patient's voice symptoms from other organic voice disorders and other functional voice problems. Several different treatment modalities are included in the managements of FD. Voice therapy is in charge of the main role in treatment of FD. Medical treatment is also necessary when patient has general problems which would affect voice production. Vocal folds mucosal lesions can cause FD even the lesion is minor. In this case proper surgical intervention helps to improve the symptom of FD. Psychiatric consultation should be considered when the patient has psychological problems.
