The Modified A-Space method was used to select 4 speakers in a study that relates occlusal classes with vowel, fricative and stop production adaptations. It allows the detailed characterization of the XRMB-SPD speakers not just in terms of mid-sagittal-plane area, but also in terms of antero-posterior distance, occlusal plane area, posterior pharynx wall tilt, mandible arch width, and oral cavity volume. This last measure has proven to be far more reliable and has revealed more speaker dependent characteristics than the measure previously proposed in Honda, Maeda, Hashi, Dembowski and Westbury (1996).
