【摘要】：發(fā)音運(yùn)動(dòng)可視化是指將人的發(fā)音過程通過三維模型模擬出來。發(fā)音運(yùn)動(dòng)分析與合成系統(tǒng)涉及生理語音學(xué)、語音生理圖像、人的發(fā)音機(jī)制及控制的生理計(jì)算模型等領(lǐng)域的相關(guān)技術(shù),主要方法是建立超聲數(shù)據(jù)庫與三維生理模型數(shù)據(jù)庫并將在二者之間建立映射關(guān)系從而實(shí)現(xiàn)發(fā)音運(yùn)動(dòng)的可視化,建立一個(gè)完善的發(fā)音運(yùn)動(dòng)分析與合成系統(tǒng)。目前,在對(duì)中文發(fā)音可視化研究方面存在欠缺,尤其是通過三維模型的可視化方面,因此發(fā)音運(yùn)動(dòng)分析與合成系統(tǒng)在語言學(xué)習(xí),特別是第二語言學(xué)習(xí)及言語矯正方面以及言語矯正方面有很重要的意義。近年來,隨著我們國家國際地位的提升,“漢語熱”在很多地方興起,現(xiàn)在漢語學(xué)習(xí)大部分都依靠“孔子學(xué)院”之類的傳統(tǒng)教學(xué)培訓(xùn)機(jī)構(gòu),但是建立以及運(yùn)營這些培訓(xùn)學(xué)校所需的人力、物資的消耗是非常巨大的。本文中我們采集了7個(gè)漢語原因因素,建立了超聲數(shù)據(jù)庫。在三維生理模型方面,為了涵蓋大部分的中文發(fā)音器官的形態(tài)變化,我們計(jì)算了近20萬組運(yùn)動(dòng)參數(shù),通過大量計(jì)算建立了三維模型數(shù)據(jù)庫。通過天津大學(xué)超算中心建立三維發(fā)聲模型的數(shù)據(jù)庫,以TPS(薄板樣條函數(shù))的方法實(shí)現(xiàn)超聲圖像到三維模型的映射,實(shí)現(xiàn)通過超聲圖像驅(qū)動(dòng)三維模型,使發(fā)音運(yùn)動(dòng)可視化。最后,搭建了三維模型可視化系統(tǒng),將于超聲圖像匹配后的三維模型進(jìn)行輸出,達(dá)到發(fā)音可視化的目的。
[Abstract]:The visualization of pronunciation movement is to simulate the process of pronunciation by three-dimensional model. The phonetic motion analysis and synthesis system involves related techniques in the fields of physiological phonetics, phonetics and images, human pronunciation mechanisms and controlled physiological computing models, etc. The main method is to establish the ultrasonic database and the three-dimensional physiological model database and establish the mapping relationship between them to realize the visualization of pronunciation movement and to establish a perfect phonetic motion analysis and synthesis system. At present, there are some deficiencies in the research of Chinese pronunciation visualization, especially through the visualization of 3D models, so the speech motion analysis and synthesis system is used in language learning. In particular, second language learning and speech correction are of great significance. In recent years, with the promotion of our country's international status, "Chinese craze" has risen in many places. Nowadays, most of our Chinese learning depends on traditional teaching and training institutions such as Confucius Institutes. But the human and material costs of building and running these schools are enormous. In this paper, we collected 7 Chinese cause factors and established the ultrasonic database. In order to cover most of the morphological changes of Chinese phonetic organs, nearly 200000 groups of motion parameters were calculated and the 3D model database was established by a large number of calculations. In this paper, the database of 3D phonation model is established in Tianjin University supercomputer Center, and the mapping from ultrasonic image to 3D model is realized by using TPS (thin sheet spline function) method. The 3D model is driven by ultrasonic image and the pronunciation motion is visualized. Finally, a 3D model visualization system is built to output the 3D model after ultrasonic image matching to achieve the purpose of pronunciation visualization.
