The aim of the investigation is to compare voice and speech quality in alaryngeal patients using esophageal speech (ESOP, eight subjects), electroacoustical speech aid (EACA, six subjects) and tracheoesophageal voice prosthesis (TEVP, three subjects). The subjects reading a short story were recorded in the sound-proof booth and the speech samples were acoustically analysed. Speech sound production was judged by 15 students of phonetics. The following variables were considered: (1) voice quality: fo, jitter, shimmer and harmonic-to-noise ratio, (2) speech sound production: number of recognized VCV syllables, and (3) temporal organization of speech: duration of the phonetic block, number of syllables in the phonetic block, rate of speech, rate of articulation and number of syllables in the longest phonetic block. The results showed that nearly normal air-stream source (lungs) in speech production of speakers with tracheoesophageal prosthesis significantly contributed to the speech timing and speech intelligibility of the alaryngeal speakers.
本研究旨在比较无喉患者使用食管言语（ESOP，8名受试者）、电声学言语辅助装置（EACA，6名受试者）和气管食管语音假体（TEVP，3名受试者）时的嗓音和语音质量。让受试者在隔音室中朗读一篇短篇小说，并对语音样本进行声学分析。由15名语音学专业的学生对语音产生进行评判。考虑了以下变量：（1）嗓音质量：基频、抖动、闪烁和谐波噪声比，（2）语音产生：可识别的VCV音节数量，以及（3）语音的时间组织：语音块的持续时间、语音块中的音节数量、语速、发音速度和最长语音块中的音节数量。结果表明，使用气管食管假体的说话者在言语产生中具有近乎正常的气流源（肺部），这对无喉说话者的言语节奏和言语清晰度有显著贡献。
