The speech intelligibility of patients who have undergone partial surgical resection of the maxilla was investigated. The intelligibility characteristics of connected discourse in each patient were compared under three experimental conditions: presurgical, postsurgical with immediate prosthetic obturation, and postsurgical with definitive prosthetic obturation. The ability of untrained listeners to differentiate between presurgical speech and postsurgical speech following definitive prosthetic treatment was also studied. Each subject recorded a standard passage of connected discourse, the Rainbow Passage, under the three conditions stated above. Each of the 24 recordings was then segmented into 23 phrases and presented over earphones to listeners. A group of 10 listeners evaluated each recording, or a total of 240 listeners was used. The recordings were graded by the number of words correctly written. Analysis of variance showed no significant loss in intelligibility across the three conditions. A group of 50 listeners than evaluated sentence pairs containing samples of presurgical speech and speech produced following surgery and definitive prosthetic obturation. Their task was to judge whether there was a difference between the two speech samples. This was done in a classroom over loudspeakers. Sign-test procedures revealed that listeners could differentiate presurgical speech samples from postsurgical speech with definitive prosthetic obturation in four of the eight patients studied.
对接受上颌骨部分手术切除的患者的言语清晰度进行了研究。在三种实验条件下比较了每位患者连贯话语的清晰度特征：术前、术后立即进行义齿阻塞和术后进行确定性义齿阻塞。还研究了未经训练的听众在确定性义齿治疗后区分术前言语和术后言语的能力。每位受试者在上述三种条件下录制了一段标准的连贯话语，即彩虹段落。然后将24段录音中的每一段分成23个短语，并通过耳机播放给听众。一组10名听众对每段录音进行评估，总共使用了240名听众。录音根据正确书写的单词数量进行评分。方差分析表明，在这三种条件下，清晰度没有显著损失。然后，一组50名听众对包含术前言语样本和术后及确定性义齿阻塞后产生的言语样本的句子对进行评估。他们的任务是判断两个言语样本之间是否存在差异。这是在教室里通过扩音器完成的。符号检验程序显示，在所研究的8名患者中，有4名患者的听众能够区分术前言语样本和术后确定性义齿阻塞后的言语样本。
