In this study, the relationship between the acoustic and articulatory kinematic domains of speech was examined among nine neurologically healthy female speakers using two derived relationships between tongue kinematics and F2 measurements: (1) second formant frequency (F2) extent to lingual displacement and (2) F2 slope to lingual speed. Additionally, the relationships between these paired parameters were examined within conversational, more clear, and less clear speaking modes. In general, the findings of the study support a strong correlation for both sets of paired parameters. In addition, the data showed significant changes in articulatory behaviors across speaking modes including the magnitude of tongue motion, but not in the speed-related measures.
在这项研究中，通过两种舌部运动学和 F2 测量值之间的衍生关系，研究了 9 位神经系统健康女性说话者的言语声学和发音运动学之间的关系：（1）第二共振峰（F2）频率与舌部位移，以及（2）F2 斜率与舌部速度。此外，还在会话、更清晰和不那么清晰的说话模式下检查了这些配对参数之间的关系。总的来说，研究结果支持这两组配对参数之间存在很强的相关性。此外，数据显示在说话模式下，发音行为发生了显著变化，包括舌部运动的幅度，但与速度相关的测量值没有变化。
