使舌头抵靠刚性声道表面（即，牙齿或上颚）在促进某些种类的舌头运动方面是重要的[Stone，J. Acoust.美国社会81，2207-2218（1990）]。然而，以前的研究一般只在一个狭窄的语音背景下寻找支撑，导致支撑作为一个偶然的状态，特有的特定的声音或声音组合的广泛看法。本研究使用腭电图（EPG）以及超声成像和电磁发音测定法（EMA）来描述舌头支撑在连续的语音通道，发现舌头几乎不断地支撑在运行的讲话过程中对侧表面。对KayPENTAX Palatometer数据库（Model 4333）中美国英语男性和女性使用者的档案数据进行分析表明，除了一小部分低元音和一大部分/l/的情况外，他们一直在支撑舌头。使用所有Thr.
Bracing the tongue against rigid vocal tract surfaces (i.e., teeth or palate) has been suggested to be important in facilitating certain kinds of tongue movements [Stone, J. Acoust. Soc. Am. 81, 2207–2218 (1990)]. However, previous studies have generally sought bracing in only a narrow range of phonetic contexts, resulting in a widespread view of bracing as an occasional state, peculiar to specific sounds or sound combinations. The present study uses electropalatography (EPG) as well as ultrasound imaging and electromagnetic articulometry (EMA) to describe tongue bracing in continuous speech passages, finding that the tongue is almost constantly braced against lateral surfaces during running speech. Analysis of archival data from the male and female speakers of American English in the KayPENTAX Palatometer Database (Model 4333) shows that they brace the tongue continuously, except during a small percentage of low vowels, and during a larger percentage of instances of /l/. Additional measures using all thr...
