| Outline of Final Research Achievements |
In this study, we aimed to development of a simplified analysis method for vocal folds-tract interaction analysis.
A vocal tract modeled by a concentrated mass model to eigenvalue analyze the speech production mechanisms. This model consists of masses, connecting linear springs, connecting dampers, base support dampers, and base support springs. A frequency response analysis of this model accorded with a measurement using the model of the vocal organ to some extent.
In addition, we proposed model for vocal folds-tract interaction analysis, in which vocal folds modeled as a mass, a connecting linear spring, a connecting damper. this model indicated a possibility for analysis of self-oscillation of the vocal folds.
