Research Abstract |
The patient group with mandibular prognathism and the normal occlusion group participated in this study. The converted sounds were analyzed using a speech visualization system. In this procedure, the formant-frequencies were converted into three primary color signals, and the phoneme characteristics were demonstrated as special colors. For quantification, we quantified the characteristics of the articulation stage on a graph, and we quantified the unevenness using radar chart. Using these methods, we compared the patient group with the normal occlusion group. In the graph, the preoperative sounds in the patient group were distributed widely,but the postoperative sounds was approximated to the normal occlusion group. Furthermore, on the radar chart, the postoperative sounds in the patient group demonstrated an apparent improvement of the articulation pattern, approaching those of the normal occlusion group.This system is useful for visual and quantitative analysis.
