五个正常说话的成年男性被教导使用电喉头说话。语音音素的可理解性是通过封闭集词辨别测试和语音材料的转录来测量的。在单词识别测试和语音记录测试中，五名说话者的平均正确率分别为90%和57%。一项对感知混淆的分析显示，错误最常与发声特征有关，很少发生发音错误的方式或地点。在观察到的变量范围内，语音和直接从电喉部辐射的噪声的强度，辐射噪声的频谱和说话速率都没有被发现是可理解性的决定因素。
Five normal-speaking adult males were taught to produce speech using an electrolarynx. Speech phoneme intelligibility was measured in a closed-set word discrimination test and through phonetic transcriptions of the spoken materials. Mean percentages of correct identification for the five talkers were 90% and 57% for the word-identification test and phonetic transcription, respectively. An analysis of perceptual confusions revealed that errors were most frequently associated with the voicing feature and that few manner or place of articulation errors occurred. Over the range of variables observed, the intensity of both the speech and the noise radiating directly from the electrolarynx, the spectrum of the radiated noise and speaking rate were not found to be determinants of intelligibility.
