Three new two-mass models of the vocal cords are treated. First, the features, structure, and differential equations of motion are described for each of the new models and compared with those of previous models. Second, performances of the models are discussed in terms of glottal volume flow, glottal area, radiated sound pressure, trajectories of mass movement, running spectra of the output sound pressure, and perceptual naturalness of the output sound. Finally, the major effects of glottal source-vocal tract interaction including skewing, truncation, and superposition are investigated, using one of the simplest types of two-mass models and two types of load representing the vocal tract.
研究了三种新的声带双质量模型。首先，描述了每个新模型的特征、结构和运动微分方程，并与先前模型进行了比较。其次，从声门体积流量、声门面积、辐射声压、质量运动轨迹、输出声压的运行频谱以及输出声音的感知自然度等方面讨论了模型的性能。最后，使用最简单的双质量模型类型之一和两种代表声道的负载，研究了声门源 - 声道相互作用的主要影响，包括倾斜、截断和叠加。
