摘　　要：对发音时的舌体进行超声成像是分析舌体运动的一种有效方法,而对舌体超声成像序列的处理分析可以为语言学、语音学、语音处理和舌体建模等应用领域提供有价值的信息。基于国内外现有研究成果,归纳了舌体超声成像中舌体轮廓线的跟踪与提取技术,分析了不同舌体轮廓线的量化比较方法,指出了生理发音舌体模型的构建方法。旨在通过舌体超声技术的梳理,能够在发音生理研究和语言研究方面为有关研究人员提供参考,在将来的研究中,能够改进相关技术,并将计算机领域中的新算法、新模型应用于发音生理舌体研究中,进一步提高描述语音现象的科学性和准确性。The ultrasound tongue imaging in pronunciation is an effective way to analyze the tongue movement.However,the processing analysis for ultrasound tongue imaging sequence can provide valuable information for various application fields,such as linguistics,phonetics,speech processing,speech engineering,tongue modeling,etc.Based on the existing research findings at home and abroad,this paper concluded the tracking and extraction techniques of tongue contour,analyzed quantitative compa-rison method of different tongue contour and pointed out the measuring method for tongue movement.It was expected that which could provide technical methods for the related researchers in the study of pronunciation physiology and language study,and the new algorithm and new model in computer fields could be applied in pronunciation physiological tongue study through the rela-ted technique improvement,improving the scientific and accurate description of the phenomenon of phonetic phenomena.
