| summary | This talk will present our research studying the tongue, which is perhaps the most critical structure in the articulation of speech. The tongue is well suited to creating the many diverse shapes used to produce speech because of its soft tissue composition and complex muscle architecture. Measurement of the tongue has become increasingly thorough in the last 30 years, partly because imaging techniques are able to detail the tongue's function despite its inaccessible location. This presentation will focus on tagged Cine-MRI and its application to normal and glossectomy speech. The talk will also present our recent use of high-resolution and diffusion tensor imaging, which capture anatomical features and contribute to the interpretation of motion data. Finally, the talk will present preliminary results of our collaborative work developing and validating a finite element tongue model, designed to study sleep apnea and the effects of a tongue implant on speech. |
