在开发用于个体发声的高保真声带振动计算模型时，会遇到模型参数未知和发声个体特有特征的模型验证等典型问题。在目前的研究中，我们采用了诱发的兔子发声来探讨其中的一些问题。特别是，兔子声带组织的机械性能对于个别受试者来说是未知的。在该模型中，我们结合了基于兔喉磁共振(MR)扫描的3D声带模型和声门气流的简单一维(1D)模型来执行声带动力学的快速模拟。然后，将该混合三维(3D)/1D模型与每个个体受试者的实验测量一起用于确定声带特性。对于单个受试者，最终模型的振动频率和变形幅度匹配得很好。本文所采用的建模和验证方法可能对将来开发特定对象的声带振动计算模型有用。
When developing high-fidelity computational model of vocal fold vibration for voice production of individuals, one would run into typical issues of unknown model parameters and model validation of individual-specific characteristics of phonation. In the current study, the evoked rabbit phonation is adopted to explore some of these issues. In particular, the mechanical properties of the rabbit's vocal fold tissue are unknown for individual subjects. In the model, we couple a 3D vocal fold model that is based on the magnetic resonance (MR) scan of the rabbit larynx and a simple one-dimensional (1D) model for the glottal airflow to perform fast simulations of the vocal fold dynamics. This hybrid three-dimensional (3D)/1D model is then used along with the experimental measurement of each individual subject for determination of the vocal fold properties. The vibration frequency and deformation amplitude from the final model are matched reasonably well for individual subjects. The modeling and validation approaches adopted here could be useful for future development of subject-specific computational models of vocal fold vibration.
