利用生物力学舌模型预测舌手术对言语产生的影响
Use of a biomechanical tongue model to predict the impact of tongue surgery on speech production
摘要:
本文提出了舌头手术对语音产生的后果的预测。为此,使用舌的3D有限元模型,其将该咬合架表示为可变形结构,其中舌肌肉解剖结构被逼真地描述。两个例子的舌头手术,这是常见的口腔癌的治疗,建模,即hemiglossecotomy和大切除口底。在这两种情况下,模拟三种可能的重建,假设皮瓣具有不同的刚度。在没有任何补偿策略的情况下,即,使用与在非病理条件下产生这些元音相关的相同的运动命令,计算基数元音/i、a、u/的预测。将估计的声道面积函数和相应的共振峰与正常情况下得到的结果进行了比较
英文摘要:
This paper presents predictions of the consequences of tongue surgery on speech production. For this purpose, a 3D finite element model of the tongue is used that represents this articulator as a deformable structure in which tongue muscles anatomy is realistically described. Two examples of tongue surgery, which are common in the treatment of cancers of the oral cavity, are modelled, namely a hemiglossectomy and a large resection of the mouth floor. In both cases, three kinds of possible reconstruction are simulated, assuming flaps with different stiffness. Predictions are computed for the cardinal vowels /i, a, u/ in the absence of any compensatory strategy, i.e. with the same motor commands as the one associated with the production of these vowels in non-pathological conditions. The estimated vocal tract area functions and the corresponding formants are compared to the ones obtained under normal conditions
