摘　　要：为提高处理舌位超声成像数据的效率,研发一套基于超声影像的舌位参数提取及分析软件,包括舌位曲线提取功能模块和舌位曲线参数分析功能模块,前一模块采用自动拟合和手工标记关键点相结合的方法,后一模块采用SPSS工具对舌位曲线帧距和舌位空间距离进行量化统计分析。该软件可精确分析发音人发音时的舌位运动轨迹及相关参数,并通过统计图实时直观显示,不但为批量处理更多的舌位运动数据提供了可能,也为不同学科研究者分析发音过程中舌位运动的生理参数变化提供了便捷的技术支持。For the purpose of improving the efficiency of processing tongue position ultrasound imaging data,a set of tongue position parameter extraction and analysis software based on ultrasound images is developed,including a tongue position curve extraction function module and a tongue position curve parameter analysis function module.The previous module used a combination of automatic fitting and manual marking of key points.The latter module used SPSS tools to quantitatively analyze the tongue position curve frame distance and tongue position spatial distance.The software could accurately analyze the tongue movement trajectory and related parameters of the speaker during the pronunciation,and display it intuitively in real time through statistical graphs.It not only provided the possibility for batch processing of more tongue movement data,but also provided convenient technical support for researchers in different disciplines to analyze the physiological parameter changes of tongue movement during pronunciation.
