Table I.

Area vectors for each vocal tract shape. Each original area function has been segmented to consist of 44 area sections given in cm²; the length of each section is given by Δ in cm. The glottal end of each area vector is at section 1 and the lip end at section 44. The total vocal tract length (VTL) in cm is computed as 44 Δ.
