Abstract

Identification and quantification of speech variations in velar production across various phonological environments have always been an interesting topic in speech motor control studies. Dynamic magnetic resonance imaging has become a favorable tool for visualizing articulatory deformations and providing quantitative insights into speech activities over time. Based on this modality, it is proposed to employ a workflow of image analysis techniques to uncover potential deformation variations in the human tongue caused by changes in phonological environments by altering the placement of velar consonants in utterances. The speech deformations of four human subjects in three different consonant positions were estimated from magnetic resonance images using a spatiotemporal tracking method before being warped via image registration into a common space-a dynamic atlas space constructed using four-dimensional alignments-for normalized quantitative comparisons. Statistical tests and principal component analyses were conducted on the magnitude of deformations, consonant-specific deformations, and internal muscle strains. The results revealed an overall decrease in deformation intensity following the initial consonant production, indicating potential muscle adaptation behaviors at a later temporal position in one speech utterance.

识别和量化不同语音环境下的发音变化一直是语音运动控制研究中的一个有趣课题。动态磁共振成像已成为可视化发音变形和定量了解语音活动随时间变化的有利工具。基于这种模式,我们建议采用图像分析技术的工作流程,通过改变元音辅音在语篇中的位置,揭示语音环境变化对人类舌头造成的潜在变形变化。四名受试者在三种不同辅音位置下的语音变形是通过时空跟踪方法从磁共振图像中估算出来的,然后通过图像配准将其扭曲到一个共同的空间--一个利用四维配准构建的动态图集空间--进行归一化定量比较。对变形幅度、特定辅音变形和内部肌肉应变进行了统计测试和主成分分析。结果表明,在最初发出辅音后,变形强度总体上有所下降,这表明肌肉在一个语篇的较后时间位置可能存在适应行为。
