目的：探讨腭部中段上颌义齿连接体的宽度和截面形状对语音识别系统辅音语音输出准确性的影响。方法：选择9名正常牙列的成年人，男4名，女5名，年龄24-26岁。六个音：[i]、[t i]、[i]、[ni]、[çi]和[ki]。制造实验连接器以模拟杆（窄的，8-mm宽）和板（宽的，20-mm宽）。两种类型的横截面形状在矢状面被指定：平坦和丰满的边缘。利用语音识别系统计算语音段标记出现率来衡量语音输出的准确性。结果：[ni]与[ki]的正确标签平均出现率（MARC）显著降低，其中[ni]的边缘较宽（窄连接符），[ki]的边缘较平（宽连接符），[ki]的边缘较平（宽连接符），[ni]的边缘较宽（宽连接符），[ki]的边缘较平（宽连接符），[ni]的边缘较平（宽连接符），[ki]的边缘较平（宽连接符），[ni]的边缘较平（宽连接符），[ki]的边缘较平（宽连接符），[ki]的边缘较平（宽连接符），[ni]的边缘较平（宽连接符），[ki]的边缘较平（宽连接符），[ki]的边缘较平（宽连接符），[ki]的边缘较平（宽连接符），[ni]的边缘较平（宽连接符），[ki]的边缘较平（宽连接符）的边缘较平（宽连接符），[ki]的边缘较平（宽连接对于[çi]，MARC倾向于使用平板较低。结论：连接子的宽度和横截面形状对腭部辅音的清晰度影响有限。
Objective:To investigate the effects of the width and cross-sectional shape of the major connectors of maxillary dentures located in the middle area of the palate on the accuracy of phonetic output of consonants using an originally developed speech recognition system.Patients and Methods:Nine adults (4 males and 5 females, aged 24-26 years) with sound dentition were recruited. The following six sounds were considered: [∫i], [t∫i], [ɾi], [ni], [çi], and [ki]. The experimental connectors were fabricated to simulate bars (narrow, 8-mm width) and plates (wide, 20-mm width). Two types of cross-sectional shapes in the sagittal plane were specified: flat and plump edge. The appearance ratio of phonetic segment labels was calculated with the speech recognition system to indicate the accuracy of phonetic output. Statistical analysis was conducted using one-way ANOVA and Tukey's test.Results:The mean appearance ratio of correct labels (MARC) significantly decreased for [ni] with the plump edge (narrow connector) and for [ki] with both the flat and plump edge (wide connectors). For [çi], the MARCs tended to be lower with flat plates. There were no significant differences for the other consonants.Conclusion:The width and cross-sectional shape of the connectors had limited effects on the articulation of consonants at the palate.
