粤语无喉人发声方法的研究

Speech Methods of Laryngectomees Who Speak Cantonese

文中将40例无喉患者平均分成四组,分别采用食管、气管食管、电子助讲器和气动式助讲器辅助发音.另设10例正常人为对照组,分别计算受试者讲一句话时的平均基频.研究结果显示,气管食管语与正常声带语音的平均基频相近,食管语及气动式助讲器的平均基频值较高,至于电子助讲器的平均基频值则最低.

Forty laryngectomees were divided into 4 groups. Each group had 10 patients, who speech with Esophageal, Tracheo- esophageal, Electrolaryngeal and Pneumatic artificial laryngeal respectively. Ten normal speakers were included as control group. The average fundamental frequencies (F0) were included as calculated after speaking a sentense. The result showed that it was similar between normal speakers and Tracheo-esophageal speech,the average F0 of Esophageal and Pneumatic artifcial Laryngeal speech were highest, and that of Electrolaryngeal speech was lowest.
