음성장애의 중증도와 발화 수준에 따른 말 명료도의 변화 연구
표화영(Hwayoung Pyo) 한국음성학회 2008 음성과학 Vol.15 No.2
The purpose of this study was to investigate the speech intelligibility of voice disordered patients when we consider the severity and utterance level as variables. Based on the severity level, 12 patients were divided into three groups, G1, G2, and G3 group, respectively. Words, phrases and sentences produced by the speakers were judged by four listeners with normal hearing, and we compared the intelligibility scores of the three groups. As a result, the speech intelligibility was decreased as the severity level was increased, and the difference was statistically significant. However, the mean difference among words, phrases and sentences was not significant, and the variation of intelligibility according to the utterance level was not under the regular rules.

정상 성인 화자와 음성장애 성인 화자의 문단낭독 시 호흡단락에 대한 비교 연구: 예비연구
표화영(Pyo, Hwayoung),김소연(Kim, Soyeon),백승국(Baek, Seungkuk) 한국음성학회 2014 말소리와 음성과학 Vol.6 No.4
The present study was performed to investigate the characteristics of breath groups while reading paragraph in normal adults and adult patients with voice disorders. 10 normal females(avr. 20.6 yrs.), 10 young voice disorder females(avr. 33.5 yrs., P1 group), and 10 old voice disorder females(avr. 56.3 yrs., P2 group) read a paragraph of 210 syllables. By using the ‘Running Speech’ program of the Phonatory Aerodynamic System(PAS), total duration, numbers of breath groups, duration per breath group, and numbers of syllables per breath group were measured, and their correlations with aerodynamic measurement results of reading were analyzed. As a result, in total duration, numbers of breath groups, normals scored highest and P2 group speakers, lowest. Normals showed the longest duration per breath group which was not significant. P2 group speakers showed the highest numbers of syllables per breath group. Correlation analysis showed significantly high correlation scores of total duration and expiratory airflow; numbers of breath groups and inspiratory volume.

문단낭독 시 속삭임 발화와 정상 발화의 공기역학적 특성
표화영(Pyo, Hwayoung) 한국음성학회 2014 말소리와 음성과학 Vol.6 No.3
The present study was performed to investigate and discuss the aerodynamic characteristics of whispered and normal speech during reading paragraph tasks. 39 normal females(18-23 yrs.) read ‘Autumn’ paragraph with whispered and normal phonation. Their readings were recorded and analyzed by ‘Running Speech’ in Phonatory Aerodynamic System(PAS) instrument. As results, during whispered speech, the total duration was longer and the numbers of inspiration were more frequently shown than normal speech. The Peak expiratory and inspiratory rate were higher in normal speech, but the expiratory and inspiratory volume were higher in whispered speech. By correlation analysis, both whispered and normal speech showed significantly high correlation between total duration and expiratory/inspiratory airflow duration; numbers of inspiration and inspiratory airflow duration; expiratory and inspiratory volume. These results show that whispered speech needs more respiratory effort but shows poorer aerodynamic efficacy during phonation than normal speech.

배경소음의 정도에 따른 음성장애 환자 발화 명료도 연구
표화영(Pyo,Hwayoung) 한국음성학회 2011 말소리와 음성과학 Vol.3 No.3
The present study was performed to investigate the intelligibility of voice disorder patients by providing the various background noise levels. Four sets of 12-sentence-stimuli produced by 11 voice disorder patients were prepared, and 5 minute-news from radio broadcasting studio were used as a background noise. 30 listeners assigned intelligibility score of each sentence with visual analog scale. Each set of sentences was provided with 20dB, 10dB, 0dB noise (same intensity with stimuli), and, finally, with no noise. As results, as background noise level increased, intelligibility scores were lowered with statistical significance. Even though in the same severity, more loud background noise showed much lower scores than less loud noise. When 10dB noise was provided, intelligibility scores showed the biggest difference among the degree of severity.

언어치료사의 음성증상 및 한국어판 음성장애지수에 대한 예비연구
송윤경(Song Yunkyung),표화영(Pyo Hwayoung) 한국음성학회 2010 말소리와 음성과학 Vol.2 No.2
Speech language pathologists depend on their voice for livelihood and are high risk group of voice disorders. But there are few studies on their prevalence of voice symptoms and voice handicap index. This study aimed to evaluate prevalence of voice symptoms and Korean voice handicap index with 86 speech language pathologists and 90 individuals employed in other occupations. We analyzed self-reported voice symptoms and voice handicap index using a questionnaire for this study. The results showed that the prevalence of voice symptoms of speech language pathologists is 60.5% and voice handicap index scores of speech language pathologists group are significantly higher than those of control group in physical and total score. And we found that alcohol history was a risk factor for voice symptoms. These findings indicate that special vocal hygiene program for speech language pathologists and follow up studies for comparisons of prevalence of voice symptoms and voice handicap index with other professional voice users are necessary.
