【摘要】：嘴唇是人類的發(fā)音器官之一,不僅可以輔助產(chǎn)生語(yǔ)音,還可以在視覺(jué)上輔助聽眾對(duì)言語(yǔ)進(jìn)行感知。因此對(duì)于嘴唇運(yùn)動(dòng)及其變形機(jī)制的研究是語(yǔ)音生成領(lǐng)域的一個(gè)重要方面,對(duì)于揭示人類語(yǔ)音產(chǎn)生的基本控制原理有著非常重要的意義。目前國(guó)內(nèi)外對(duì)于嘴唇的運(yùn)動(dòng)及其生理控制機(jī)制的研究非常有限,還沒(méi)有研究成果可以合理的揭示嘴唇的運(yùn)動(dòng)是如何產(chǎn)生的,特別是對(duì)于嘴唇前突的動(dòng)作,其生理控制機(jī)制長(zhǎng)期以來(lái)一直都沒(méi)有被發(fā)現(xiàn)。嘴唇產(chǎn)生運(yùn)動(dòng)的方式與舌頭是類似的,它們都是依靠肌肉的收縮引起軟組織產(chǎn)生形變而運(yùn)動(dòng),而不依靠人類的骨骼系統(tǒng)。目前最有效的探究人類發(fā)音器官的生理控制機(jī)制的手段是通過(guò)構(gòu)建生理模型的方法進(jìn)行生物力學(xué)仿真。本課題的主要目的是基于肌肉可視化和構(gòu)建生理模型的方法探究嘴唇前突的生理控制機(jī)制。通過(guò)對(duì)國(guó)內(nèi)外相關(guān)研究成果的分析研究,我們提出了一個(gè)嘴唇前突的可能的生理控制機(jī)制,在口周肌肉群中,我們重點(diǎn)關(guān)注口輪匝肌的唇周部,因?yàn)樗拷谇粋?cè)的唇組織,這樣的幾何形態(tài)預(yù)示著它的收縮會(huì)引起嘴唇內(nèi)側(cè)和外側(cè)唇組織不同比例的收縮。為了驗(yàn)證我們提出的嘴唇前突的生理控制機(jī)制,本文通過(guò)物理實(shí)驗(yàn)和有限元分析的方法對(duì)口輪匝肌唇周部的生理作用進(jìn)行了分析,并基于高清的核磁共振圖像提取了下唇和下顎的生理形態(tài),在ArtiSynth平臺(tái)上構(gòu)建了下唇-下顎的動(dòng)態(tài)的三維復(fù)合生理模型。
[Abstract]:Lips are one of the speech organs of human beings, which can not only help to produce speech, but also help listeners to perceive speech visually. Therefore, the study of lip movement and its deformation mechanism is an important aspect in the field of speech production, and it is of great significance to reveal the basic control principle of human speech production. At present, the research on the movement of lips and its physiological control mechanism is very limited at home and abroad, and no research results can reasonably reveal how the movement of lips is produced, especially for the movement of lip protrusions. Its physiological control mechanism has not been discovered for a long time. The lips move in a similar way to the tongue. They move on the basis of soft tissue deformation caused by muscle contraction, rather than on the human skeletal system. At present, the most effective way to explore the physiological control mechanism of human vocal organs is to construct physiological models for biomechanical simulation. The main purpose of this study is to explore the physiological control mechanism of anterior lip protrusion based on muscle visualization and physiological modeling. Through the analysis of the related research results at home and abroad, we put forward a possible physiological control mechanism of anterior lip protrusion. In the perioral muscle group, we focus on the labial part of orbicularis oris muscle because it is closer to the labial tissue of the oral side. This geometry indicates that its contraction will cause different proportions of contraction in the medial and lateral lip tissues of the lips. In order to verify the physiological control mechanism of anterior lip protrusion proposed by us, the physical experiment and finite element analysis were used to analyze the physiological function of the lip around the orbicularis oris muscle. Based on the high-definition MRI images, the physiological morphology of the lower lip and the lower jaw was extracted, and the dynamic three-dimensional composite physiological model of the lower lip and the lower jaw was constructed on the ArtiSynth platform.
