| 英文摘要 | 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 comparison 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 related technique improvement, improving the scientific and accurate description of the phenomenon of phonetic phenomena. |
