隨著近年來身心障礙的族群越來越受到重視，現今的社會有越來越多的構音障礙者會尋求語音上的治療以及復健。因此，發展一套語言治療師能用來輔助及復健治療的工具就顯的愈來愈重要。本研究發展一套以軟體為主的可見式語音診斷與復健系統，使用者可以透過使用者介面分別對構音正常與構音障礙個案錄下語音訊號，並比對兩組語音信號的波形、頻譜、聲譜及基頻等資訊，提供量化的客觀分析。為了評估此系統的實用性、功能性以及正確性，本研究透過與台北榮民總醫院以及衛生福利部桃園醫院新屋分院復健科語言治療團隊的合作，經由人體測試委員會的核准之後，利用電腦收錄了共十三組 (其中包含八位成人，五位小孩；九位男性，四位女性)音訊來做後續的結果分析以及比較。根據實測結果顯示，本研究實現了一個可以呈現出正常語者與具有構音障礙之個案的構音差異的可見式語音診斷與復健系統。此外，透過與Praat軟體比較的結果顯示，本研究的系統較適合於使用者在比對、分析、訓練以及復健上使用，且兩者在功能性 (頻譜，聲譜，基頻等)的使用上會得到近似的結果。總而言之，在臨床上，語言治療師可運用此系統作為評估、診斷以及復健構音障礙者發音狀況的工具。

As more attention paid to the handicapped people recently, more patients with articulatory disorder look for speech therapy. Therefore, to develop a tool which could assist the speech therapist to provide rehabilitation service to more patients is getting more important. The purpose of this study was to develop a software-based visible speech diagnostic and rehabilitation system (VSDRS) which could be used to record and compare the speech signals from the normal speaker and the patient with articulation disorder via the user interface. In this user interface, the clinical users could compare these two signals in the forms of the speech signal, spectrum, spectrogram and fundamental frequency to provide a quantitative analysis. In order to evaluate the usefulness, functionality and accuracy of the system, this study analyzed and compared thirteen (i.e., eight adults and five children, or nine male and four female subjects) speech recordings provided from the cooperation of Taipei Veterans General Hospital and Tao Yuan General Hospital, Ministry of Health and Welfare-Sinwu Branch approved by the Internal Review Board (IRB). The results showed that the VSDRS was realized and able to indicate the difference between the normal speaker and patient with articulatory disorder. Furthermore, when compared with the free software, the Praat system, our VSDRS would be more suitable for clinical users to train their patients for rehabilitation purpose in addition to their functional similarity. In summary, the speech therapists could apply this VSDRS for diagnosis, assessment, and rehabilitation of patients with articulatory disorders.
