How modeling entrance loss and flow separation in a two-mass model affects the oscillation and synthesis quality

Self-oscillating bar-mass models of the vocal folds are frequently used as the voice source in articulatory speech synthesis. For these models, a number of ways to handle the entrance loss and the flow separation in the glottis have been proposed. However, the effect of different modeling choices on vocal fold oscillation and glottal flow, and on the quality of synthesized speech has been rarely examined. In this study, a modified two-mass …
