An exploratory model of speech intelligibility for healthy aging based on phonatory and articulatory measures

The aims of the current study were to determine age-related changes to the phonatory and articulatory subsystems and to investigate an exploratory model of intelligibility for healthy aging based on phonatory and articulatory measures. Fifteen healthy, older adults (55–81 years) and 15 younger adults (20–35 years) participated in instrumental assessments of the phonatory (aerodynamic, acoustic) and articulatory (kinematic) subsystems.
