The perception and production of linguistic tone was investigated in utterances spoken by Thai alaryngeal speakers. Thai is a tone language with five phonemic tones. High-quality tape recordings of five monosyllabic words produced by 2 esophageal, 1 electrolaryngeal, and 5 normal, native Thai speakers were subjected to perceptual and acoustic analysis. Results from the phonemic identification tests indicated that tones produced by alaryngeal speakers were not only perceived at much lower levels of accuracy than those produced by normal speakers, but the patterns of tonal confusions for alaryngeal speakers were also dissimilar to those for normal speakers. Results from fundamental frequency (Fo) analysis revealed that the performance deficit of alaryngeal speakers could be related to specific characteristics of their Fo contours. Findings are interpreted to highlight the importance of (a) language, (b) type of prosody, (c) form of alaryngeal speech, and (d) Fo level and direction on linguistic assessments of Fo control in alaryngeal speech.
对泰国无喉者所说话语中的语调感知和生成进行了研究。泰语是一种有五个音位声调的声调语言。对2名食管发音者、1名电子喉使用者以及5名正常的泰语母语者说出的五个单音节词的高质量录音进行了感知和声学分析。音位识别测试结果表明，无喉者发出的声调不仅在准确性上比正常说话者发出的声调低得多，而且无喉者的声调混淆模式也与正常说话者不同。基频（Fo）分析结果显示，无喉者的表现缺陷可能与其Fo轮廓的特定特征有关。研究结果旨在强调（a）语言、（b）韵律类型、（c）无喉语音形式以及（d）Fo水平和方向对无喉语音Fo控制语言评估的重要性。
