In order to elucidate the articulatory characteristics of esophageal speakers, speech discrimination tests were performed on the recorded samples of skilled and unskilled esophageal speakers. It was found that the discrimination score was low for voiceless stops or fircative /h/ even in skilled subjects. For the analysis of articulatory dynamics of esophageal speakers, a palatal mold was obtained and artificial palate was prepared for electropalatograhy for each subject. The same procedure was also taken in normal subjects to obtain control data samples. Electropalatographic data in esophageal speakers indicated that the area of linguo-palatal contact for fricatives was significantly narrower compared with normal subjects. It was also found that intra-oral pressure during the production of voiceless sounds tended to be higher in esophageal speakers. These results suggested that there was a special articulatory adjustment in esophageal speakers to produce some type of consonants effectively with small amount of air supply. It was concluded that this type of articulatory adjustment must be adopted for the articulatory training for esophageal speakers during the course of rehabilitaion.

为了阐明食管发音人的发音特点，对熟练和不熟练食管发音人的录音样本进行了语音辨别测试。结果发现，即使在熟练的受试者中，无停顿停顿或停顿/h/的辨别得分也很低。为了分析食管发音人的发音动力学，我们制作了一个腭模，并为每位受试者制作了用于电腭造影的人工腭。在正常受试者中也采取相同的程序以获得对照数据样本。食管发音者的腭电图数据表明，舌腭接触摩擦音的面积显着比正常人窄。研究还发现，在食管扬声器的生产过程中，口腔内的压力往往更高。这些结果表明，食管发音者在少量供气的情况下，有一种特殊的发音调节，能有效地发出某些类型的辅音。结论：食管发音者在康复过程中的发音训练，必须采用这种发音调整方法。
