Deafs train articulation by observing mouth of a tutor, sensing tactually the motions of the vocal organs, or using speech training aids. Present speech training aids for deafs can measure only single speech parameter, or display only frequency spectra in histogram of pseudo-color. In this study, a speech training aids that can display subject's articulation in the form of a cross section of the vocal organs and other speech parameters together in a single system is to be developed and this system makes a subject know where to correct. For our objective, first, speech production mechanism is assumed to be AR model in order to estimate articulatory motions of the vocal organs from speech signal. Next, a vocal tract profile model using LP analysis is made up. And using this model, articulatory motions for Korean vowels are estimated and displayed in the vocal tract profile graphics.

Deafs train articulation by observing mouth of a tutor. sensing tactually the notions of the vocal organs, or using speech training aids. Present speech training aids for deafs can measure only single speech ter, or display only frequency spectra in histogrm or pseudo-color. In this study, a speech training aids that can display subject's articulation in the form of a cross section of the vocal organs and other speech parameters together in a single system Is aimed to develop and this system makes a subject to know where to correct. For our objective, first, speech production mechanism is assumed to be AR model in order to estimate articulatory notions of the vocal tract from speech signal. Next, a vocal tract profile mode using LPC analysis is made up. And using this model, articulatory notions for Korean vowels are estimated and displayed in the vocal tract profile graphics.

Development of Integrated Speech Training Aids for Hearing Impaired In this study, a spepch lralnlng aids that can do real-time display of vocal tract shape and other speech parameters together in a single system is implemenLed and self-training program for this system is developed. To estimate vocal tract shape, speech production process is assumed to be AR model. Through LPC analysis, vocal tract shape, intensity, and log spcclrum are calculated. And, fundamental frequency and nasality are measured using vibration sensors.

Deafs cannot speak straight voice as normal people in lack of feedback of their pronunciation, therefore speech training is required. In this study, fundamental frequency, intensity, formant frequencies, vocal tract graphic and vocal tract area function, extracted from speech signal, are used as feature parameter. AR model, whose coefficients are extracted using inverse filtering. is used as speech generation model. In connect ion between vocal tract graphic and speech parameter, articulation distances and articulation distance functions in selected 15-intervals are determined by extracted vocal tract areas and formant frequencies.

Since the 1980s, a number of professionals in the ESL/EFL field have investigated the role of pronunciation in the ESL/EFL curriculum. Applying the insights gained from the second language acquisition research, these efforts have focused on the integration of pronunciation teaching and learning into the communicative curriculum, with a shift towards overall intelligibility as the primary goal of pronunciation teaching and learning. The present study reports on the efficacy of audio-visual aids and hyper-pronunciation training method in teaching the productions of English consonants to Japanese college students. The talk will focus on the implications of the present study, and the presenter makes suggestions to teaching pronunciation to Japanese learners.

본 연구에서는 우리나라 언어재활사들의 쓰기담화 중재에 대한 교육이수 경험 및 지식 등을 포함하여 쓰기담화 중재에 대해 좀 더 전반적이고 심층적으로 현황을 파악하고 쓰기담화 중재에 대한 언어재활사의 인식과 요구를 살펴보고자 하였다. 언어재활사 110명이 응답한 설문을 통해 연구 결과를 도출하였다. 그 결과 대부분의 언어재활사들이 교과과정에서 쓰기담화 중재에 대해 학습하였음에도 불구하고 임상 현장에서의 쓰기담화 중재 적용법이 미흡하고 이 중재의 체계적이고 전문적인 지식 부족으로 인해 쓰기담화 중재에 대해 어려움을 느끼고 있다는 것을 알 수 있었다. 쓰기담화 중재 현황을 살펴보면 임상 현장에서 응답한 언어재활사 중 46.4%만이 쓰기담화 중재에 대한 경험이 있는 것으로 나타났다. 다시 말하면 응답자의 53.6%는 쓰기담화 중재에 대한 경험이 없는 것으로 분석되었다. 언어재활사의 쓰기담화 중재에 대한 인식 및 요구에 관한 결과, 76.4%의 언어재활사들이 쓰기담화 중재 부분이 언어치료의 중요한 영역이라고 생각한다고 답하였다. 이와 함께 담화 중재에 대한 교과과정이 필요하다고 응답한 응답자는 62.8%, 쓰기담화 중재의 지속적인 연구의 필요성에서도 90% 이상 필요하다고 하였으며, 교재 및 교구 개발에 대해서도 89.1% 필요하다고 생각하였다. 본 연구에서는 쓰기담화 중재의 언어재활사들의 경험 및 인식을 알아보았고 결과를 분석해 봄으로써 쓰기담화 중재와 관련된 교육 및 다양한 과정들이 어떻게 이루어져야 하는지에 대한 방향을 제시했다는 점에서 의의가 있다.
