본 연구에서는 음성장애 환자에서 음성 범위 프로파일(voice range profile, VRP)과 말 범위 프로파일(speech range profile, SRP)을 이용한 추정 발화 기본주파수 절대 오차(absolute error of estimated speaking fundamental frequency, AEF0)를 음성장애의 병인 집단 간에 비교하여 차이를 확인하고,각 병인 집단 별로 AEF0와 관련된 변수들 간의 상관관계를 살펴보고자 하였다. 연구대상은 음성장애로 진단된 기능적(functional, FUNC), 기질적(organic, ORGAN), 신경학적(neurogenic, NEUR) 음성장애 환자군과 정상군(normal control, NC) 각 30명(남 15명, 여 15명)으로 총 120명이었다. 각 대상자로 하여금 음성, 말 범위 프로파일 과제를 수행하도록 하고 전기성문파형검사(electroglottography, EGG)를 통해 발화 기본주파수를 측정하였다. 병인 집단 간 AEF0의 비교 결과, Grade와 Severity는 병인 집단 간 차이가 없었던 반면, AEF0_VRP와 AEF0_SUM에서 병인 집단 간 차이가 있어 AEF0_VRP는 ORGAN이 FUNC와 NC보다 높았으며, AEF0_SUM은 ORGAN이 NC보다 높았다. 또한 FUNC와 NEUR에서는 AEF0가 Grade와 양의 상관관계를 보인 반면, ORGAN은 CQ(closed quotient)와 양의 상관관계가 있었다. 따라서 병인 집단에 따라 AEF0의 적용과 관련 음성 변수를 살펴보는 데 주의를 기울여야 할 것으로 보이며, 본 연구는 이러한 임상적 판단에 대한 기초 자료를 마련하는 데 일조한 것으로 여겨진다.

The human speech contains many redundancies. To economize communication channel or memory size for a computerized synthesis of human voices, it is necessary to compress the data before sending. We have treated human speech organ as an eighth order dynamic system which is time varying as the person speaks. Using an anaylyzer of our design, each eight parameters are obtained for the vowels [아], [어], [오], [우], [으], [이], [애], and (외) of korean language with considerable discrepancies between persons. Supplying those parameters to a synthesizer which we have made, we have sucoeeded in the simulation of human speech for the above mentioned vowels of Korean language and observed that they bear all the features of the original speakers.

Literatural study for Delirious speech and Fading murmuring, the results were as follows. 1. Delirious speech and Fading murmuring are given at the speech impediment. Derious speech to be out of language's order and slur the end of his words, and Fading murmuring is to repeat in losing conscious. 2. In constrast with Delirious speech and Fading murmuring, Maniac speech is induced by a general term for manic-depressive psychosis. Luoyan is to say in a feeble voice and mumble in a sleeping condition, and Paraphasia and Solioquy are appeared in a clear mental condition. The speech impediment is caused by damages of the nervous system and speech organ, and Yuyancuoluan is appeared in a feverless condition. 3. The symptoms of Delirious speech are to utter ravings and have a loud and heavy voice, and these resemble the delirium which specially has a speech impediment and muddle in the western medical world. The symptoms of Fading murmuring are to speak ambigously, repeatedly, and illogically and so are similar to the Wernicke dysphasia which is caused by a incomprehensible conversation. 4. The causes of Delirious speech are to spread a stomach heat and the lungs pathogenic qi into heart, not to sweat in cold damage, the Three Yang Combination of syndrome, stomach repletion, yang collapse due to excessive sweat, diarrhea, after diarrhea, heat to enter the blood chamer, feces to remain in the stomach, stasis blood to enter the viscera, to carry anger to extremity, and to be constipated. the cause of Fading murmuring is to despair vacuity desertion of vital essence and energy after a serious illness. 5. The causes of delirium are general infection, postoperative states, and metabolism disorders and those of Wernicke dysphasia are disorders of the blood vessel, brain tumors and traumas. 6. Delirious speech is cured with the discrimination of vacuity and repletion. Baitong Tang(白通湯), Chaihu Guizhi Tang(柴胡桂枝湯), Chaihu Jia Longgu Muli Tang(柴胡加龍骨牡蠣湯) are prescribed in case of vacuity, while Chengqi Tang(承氣湯), Baihu Tang(白虎湯), Liangge San(凉膈散) are in case of repletion. Fading murmuring is treated with Xiao Chaihu Tang(小柴胡湯), Fuzi Tang Jiawei(附子湯加味), Shengmai San(生脈散), and Renshen Sanbai Tang(人蔘三白湯). 7. To acupunture Qimen-Xue(期門穴) is required when it is late to prescribe a medical decoction or the hyperactive liver qi attacking the spleen.

This paper explores whether there is correlation between consonants' place and duration of adjacent vowels in English and Korean. The results showed that in English the vowels preceding alveolar stops were in general longer than the vowels before bilabial or velar stops. Consonants appeared to have their inherent length due to their place and to exhibit some compensatory effects on the duration of preceding vowels. This effect can be explained in a physiological term that the tongue tip is the organ which might be more agile in articulatory movement than the tongue body for the velars or the lower lip (and the jaw) for the bilabials is and the shorter production time of the alveolars caused the lengthening of the adjacent vowels. However, this physiological account did not hold in the case of Korean, which exhibited less consistent patterns across speakers for the consonants' place and the vowel duration. The segmental duration seemed to be timed quite consistently within a language but the pattern was not universal across languages.

Reconstructive surgery in the management of head and neck cancer has evolved to include structure-specific approaches in which organ-specific treatment algorithms help optimize outcomes. Tongue cancer management and reconstruction are surgical challenges for which well-executed reconstructive plans should be completed promptly to avoid delaying any subsequently planned oncologic treatment. Crucial considerations in tongue cancer resection are the significant functional morbidity associated with surgical defects, particularly in terms of speech and swallowing, and the consequent negative impact on patients' quality of life. With the evolution of microsurgical techniques and the development of the perforator flap concept, flap options can be tailored to the characteristics of various tongue defects. This has allowed the implementation of pliable flaps that can help restore tongue mobility and yield subsequent functional outcomes. Using an evolutional framework, we present this series of reviews related to tongue reconstruction. The first part of the review summarizes flap options and flap-related factors, such as volume and tissue characteristics. Related functional aspects are also presented, including tongue mobility, speech, and swallowing, as well as ways to evaluate and optimize these outcomes.

Background and Objectives : Dysarthria refers to speech disorder that causes difficulties in speech communication due to paralysis, muscle weakening, and incoordination of speech muscle mechanism caused by damaged central or peripheral nerve system. Pitch, strength and speed are influenced by dysarthria during detonation due to difficulties in muscle control. As evaluation items, alternate motion rate and diadochokinesis have been commonly used, and articulation is also an important evaluation items. The purpose of this study is to find acoustic characteristics on sound production of dysarthria patients. Materials and Methods : Research subjects have been selected as 20 dysarthria patients and 20 subjects for control group, and voice sample was composed of bilabial, alveolar sound, and velar sound in diadochokinetic rate, while consonant articulation test was composed of bilabial plosive, alveolar plosive, velar plosive. Analysis items were composed of 1) speaking rate, energy, articulation time of diadochokinesis, 2) voice onset time (VOT), total duration (TD), vowel duration (VD), hold of plosives. Results and Conclusions : The number of diadochokinetic rate of dysarthria was smaller than control group. Both control group and dysarthria group was highly presented in the order of /t/>/p/>/k/. Minimum energy range per cycle during diadochokinetic rate of dysarthria group was smaller than control group, and presented statistical significance in /p/, /k/, /ptk/. Maximum energy range was larger than control group, and presented statistical significance in /t/, /ptk/. Articulation time, gap, total articulation time during diadochokinetic rate of dysarthria group was longer than control group and presented statistical significance. The articulation time was presented in both control group and dysarthria group in the order of /k/>/t/>/p/, while Gap was presented in the order of /p/>/t/>/k/ for control group and /p/>/k/>/t/ for dysarthria group. VOT, TD, VD regarding plosives of dysarthria group were longer than control group. Hold showed large deviation compared to control group that had appeared due to declined larynx and articulation organ motility.
