| Abstract | We explore the adequacy of low-dimensional models of the larynx to reproduce aerodynamic patterns of child speakers in the vicinity of an abduction gesture. A model of the child larynx is created by scaling an adult two-mass model coupled to a two-tube approximation of the vocal tract. This model next is fitted to oral airflow data of VhV sequences recorded from 5-year-old speakers, and using the subglottal pressure, Q-factor, and glotttal width as control parameters. Optimal values of the control parameters are computed by using the values of DC flow, rms AC flow, and ƒ0 measured at the /h/ abduction and flanking vowels as targets. The results show that the model is capable of reproducing the aerodynamic patterns with good approximation, allowing us to infer some aspects of voice control in individual speakers. |
