Abstract The tongue size can be used to evaluate normal and pathological articulation since it can be used to predict the tongue mobility within the oropharyngeal cavity. This study analyzes the relationship between the relative tongue size and tongue movement based on magnetic resonance images (MRI). The cine-and tagged-MRI are combined to obtain a new dataset which has clear vocal tract and marker points. The synthesized images are then used to analyze the relative tongue size and the tongue movement. The relative tongue size is defined as the ratio of the tongue area to the tongue area plus the oropharyngeal cavity area. A few marker points are sampled on the oral and pharyngeal surfaces to calculate the mean velocity. Comparison for different genders shows that smaller tongues have faster movements.
