The principal purpose of this study was to investigate the speech of two edentulous subjects fitted with a complete maxillary prosthesis made of three different palatal materials: aluminium, resin, stellite. The study was performed using two speakers fitted with a prosthesis (a man and a woman). They took part in the acoustic recording of logatoms read by themselves while wearing various prostheses. These recordings were tested from the auditory point of view by a series of six listeners (four men and two women) in an anechoic room. After 144 different tests, a speech reception threshold (SRT) was defined for each speaker and each different prosthesis. This SRT shows a level of speech intelligibility defined so that the lower the SRT, the more intelligible for the listener. The results show that: (i) both the material and the listener influence SRT: (P < 0.05); (ii) an interaction between the material factor and the speaker factor appears. (P < 0.05); (iii) The hierarchy factors influencing SRT are most important in the order: Listener --> material --> speaker; and (d) The group fitted with a metal prosthesis (aluminium, stellite) was more intelligible regarding the way they were perceived by others.
本研究的主要目的是调查两名无牙颌受试者佩戴由三种不同腭部材料（铝、树脂、钨铬钴合金）制成的全上颌义齿时的语音情况。研究使用了两名佩戴义齿的受试者（一名男性和一名女性）。他们在佩戴不同义齿时参与了自行朗读单音节词的声学录音。这些录音在消声室中由六名听众（四名男性和两名女性）从听觉角度进行测试。经过144次不同测试后，为每位受试者和每种不同义齿确定了言语接受阈（SRT）。该SRT显示了所定义的言语可懂度水平，即SRT越低，听众越容易理解。结果表明：（i）材料和听众均会影响SRT（P < 0.05）；（ii）材料因素和受试者因素之间存在交互作用（P < 0.05）；（iii）影响SRT的层级因素按重要性排序为：听众→材料→受试者；以及（iv）佩戴金属义齿（铝、钨铬钴合金）的组在他人对其的感知方式上更易理解。
