中矢状面舌形的因素分析（由 定性三维分析）已确定2-3个统计 基函数足以表示大多数 元音，这可能是潜在的神经运动的结果， 协调结构。 拟议研究的第一个目标将 通过找到统计基函数来扩展这个结果， 三维舌头形状。 第二和第三个目标是 研究将探索基函数可能是一种 依赖于说话者的行为，由不依赖于说话者的声学控制 限制：拟议研究的第二个目标是测试 对于基函数中依赖于说话者的变化，而第三个 目的将是确定是否扬声器依赖的变化， 基函数对元音格式频率具有显著影响。 这些实验中的所有舌头形状将通过以下方式获得： 收集并分割四个说话人的MR图像（11个元音，6 辅音）。 在拟议的研究结束时，MR图像将被 以光盘形式出版，供其他演讲稿制作之用 研究人员

Factor analysis of tongue shapes in the midsagittal plane (supported by qualitative three-dimensional analysis) has identified 2-3 statistical basis functions which are sufficient to represent the shapes of most vowels, and which may be the result of underlying neuromotor coordinative structures. The first aim of the proposed research will be to extend this result by finding statistical basis functions for three-dimensional tongue shapes. The second and third aims of this research will explore the possibility that basis functions may be a speaker-dependent behavior, governed by speaker-independent acoustic constraints: the second aim of the proposed research will be to test for speaker-dependent variation in the basis functions, while the third aim will be to determine whether speaker-dependent variation of the basis functions has a significant effect on vowel format frequencies. All of the tongue shapes in these experiments will be obtained by collecting and segmenting MR images of four speakers (11 vowels, 6 consonants). At the end of the proposed research, MR images will be published on CD-ROM for the benefit of other speech production researchers.
