Selected characteristics were compared in the speech of five tracheoesophageal, five esophageal, and 15 normal laryngeal adult speakers. Tape-recorded speech samples were measured for durational features with a stopwatch. Frequency features were analyzed with a Visi-Pitch/Apple IIE computer interface with statistical subroutines. Tracheoesophageal speech proved comparable to normal speech in maximum phonation time, speech rate, pitch pertubation (jitter), average fundamental frequency, and fundamental frequency range, but less efficient than normal speech in phrase grouping. Tracheoesophageal speech was superior to esophageal speech in maximum phonation time, speech rate, and phrase grouping, but not significantly different in pitch perturbation, average fundamental frequency, and fundamental frequency range. Explanations and clinical implications of these findings are discussed.
对5名采用气管食管造口发声的成人、5名食管发声的成人以及15名正常喉部发声的成人的语音的选定特征进行了比较。用秒表测量录音语音样本的时长特征。使用带有统计子程序的可视音高/苹果IIE计算机接口分析频率特征。结果表明，气管食管造口发声在最大发声时间、语速、音高扰动（抖动）、平均基频和基频范围方面与正常语音相当，但在短语分组方面不如正常语音有效。气管食管造口发声在最大发声时间、语速和短语分组方面优于食管发声，但在音高扰动、平均基频和基频范围方面无显著差异。讨论了这些发现的解释和临床意义。
