(palatogram). The subjects were 30 dentulous adults (21 men, 9 women). The artificial palates made of black vinyl seat covering the palate and occlusal surfaces of maxillary teeth were coated with white alginate powder and inserted into the mouths of the subjects. After pronunciation of the test sound, the tongue contact areas on artificial palate were demonstrated by wetting of powder and changing in color from white to black. Thus photographs of the palatograms were Measurements have been made on the tongue contact area of the palate and maxillary teeth during pronunciation of /sa, fi, çi, ka, ki, ta, na, ra, ja/ (palatogram). The subjects were 30 dentulous adults (21 men, 9 women). The artificial palates made of black vinyl seat covering the palate and occlusal surfaces of maxillary teeth wer coated with white alginate powder and inserted into the mouths of the subjects. After pronunciation of the test sound, the tongue contact areas on artificial palate were demonstrated by wetting of powder and changing in color from white to black. Thus photographs of the palatograms were taken. An image processor system was employed for averaging each subject's 5 samples of same sound. The averaged outline of each subject's palatograms were converted to the standardized dental arch form and added and stored into frame memory. The 60-90% of subject's common parts were extracted from the added palatograms of same sound and illustrated in different gray levels. The results indicate that the tongue-to-teeth contact area of each sound differ from the others, however, it's range is confined within cervical half of lingual surface of incisors and lingual cusps of molars.
（腭图）。受试者为30名有牙成年人（21名男性，9名女性）。由黑色乙烯基制成的人工腭覆盖上腭和上颌牙齿的咬合面，上面涂有白色藻酸盐粉末，然后插入受试者口中。发出测试音后，人工腭上的舌接触区域通过粉末变湿以及颜色从白色变为黑色得以显示。由此拍摄腭图照片。使用图像处理器系统对每个受试者相同声音的5个样本进行平均。每个受试者腭图的平均轮廓被转换为标准化牙弓形式，并添加并存储到帧存储器中。从相同声音的叠加腭图中提取60 - 90%受试者的共同部分，并以不同灰度显示。结果表明，每个声音的舌 - 牙接触区域彼此不同，然而，其范围局限于切牙舌面颈侧一半和磨牙舌尖范围内。 测量了发/sa、fi、çi、ka、ki、ta、na、ra、ja/音时上腭和上颌牙齿的舌接触区域（腭图）。受试者为30名有牙成年人（21名男性，9名女性）。由黑色乙烯基制成的人工腭覆盖上腭和上颌牙齿的咬合面，上面涂有白色藻酸盐粉末，然后插入受试者口中。发出测试音后，人工腭上的舌接触区域通过粉末变湿以及颜色从白色变为黑色得以显示。由此拍摄腭图照片。使用图像处理器系统对每个受试者相同声音的5个样本进行平均。每个受试者腭图的平均轮廓被转换为标准化牙弓形式，并添加并存储到帧存储器中。从相同声音的叠加腭图中提取60 - 90%受试者的共同部分，并以不同灰度显示。结果表明，每个声音的舌 - 牙接触区域彼此不同，然而，其范围局限于切牙舌面颈侧一半和磨牙舌尖范围内。
