Measurement method of sentence intelligibility in postoperative oral cancer patients

在我们的临床研究中，需要评估术后癌症患者在日常情况下的言语使用情况，本研究的目的是建立测量口腔癌患者言语清晰度的方法。十九口腔癌患者进行了评估，使用句子可懂度测试，这是本研究开发的。设计了一项任务来衡量沟通的成功程度。测试包括30个问题，包含2或3个关键词的理解。每个语音样本由5名幼稚者（牙科学校的学生）判断。本文还对句子可懂度与音节可懂度、会话可懂度的关系进行了研究，结果表明：1.所开发的句子可懂度测试具有较高的效度; 2.音节可懂度与句子可懂度之间存在显著的相关性，但音节可懂度与句子可懂度之间存在显著的相关性。句子可懂度得分显著高于音节可懂度得分，提示该测试可用于评价汉语语音的可懂度。句子可理解性定量、客观。结果表明，口腔癌患者的言语在句子水平上是相当可理解的。

The need to assess use of speech in everyday situations in postoperative cancer patients has become apparent in our clinical research.The purpose of this study was to establish the method for measuring sentence intelligibility in oral cancer speakers. Nineteen oral cancer patients were assessed using a sentence intelligibility test which was developed for this study. A task was designed to measure the success of the communication. A test consists of 30 questions containing 2 or 3 key words for understanding. Each speech sample was judged by 5 naivelisteners (dental school students) . The relation between sentence intelligibility and syllable intelligibility, or conversationintelligibility was also investigated.The results were as follows.1.It was clarified that the sentence intelligibility test developed had high validity.2.The significant correlation between syllable and sentence intelligibility was found. However, the score of sentence intelligibility was significantly higher than that of syllable intelligibility.It was suggested that the test developed here could evaluate the sentence intelligibility quantitatively and objectively. The results indicated the speech at sentence level in oral cancer speakers was considerable intelligible.
