Abstract
A section 52 corresponding to a given duration is sampled from sound data 50 that indicates the voice of a player collected by a microphone, and a vocal tract cross-sectional area function 54 of the sampled section is calculated. The vertical dimension 1y of the mouth is calculated from a throat-side average cross-sectional area d1 of the vocal tract cross-sectional area function 54, and the area dm of the mouth is calculated from a mouth-side average cross-sectional area d2. The transverse dimension of the mouth is calculated from the area dm and the vertical dimension 1y of the mouth.
