The achievement of intonational contrasts by 4 normal and 16 laryngectomized speakers was assessed in this project. The laryngectomized subjects represented four clinical subgroups of alaryngeal speech: esophageal, tracheoesophageal, Western Electric #5 electrolarynx, and Servox electrolarynx. High-quality tape recordings of each subject's productions of two pairs of sentences (Bev loves Bob) spoken in statement and question from were presented to 40 listeners for evaluation using a two-interval-alternative-forced-choice procedure. Intonational contrasts were achieved in a highly effective manner by the normal, esophageal, and tracheoesophageal speakers. In contrast, users of electronic artificial larynges were generally unable to achieve these intonational distinctions except for one user of the Western Electric #5 electrolarynx.
本项目评估了4名正常人和16名喉切除者实现语调对比的情况。喉切除受试者代表了四种无喉语音临床亚组：食管语音、气管食管语音、西部电气5型电子喉语音和Servox电子喉语音。以两间隔二选强制选择程序，将每个受试者以陈述和疑问语调说出的两对句子（贝夫爱鲍勃）的高质量录音播放给40名听众进行评估。正常、食管语音和气管食管语音的使用者能非常有效地实现语调对比。相比之下，除一名西部电气5型电子喉使用者外，电子人工喉使用者通常无法实现这些语调差异。
