Nineteen patients who had undergone total laryngectomy with primary tracheoesophageal puncture underwent comprehensive testing of speaking proficiency. All patients learned to use tracheoesophageal speech in the immediate postoperative period. Overall, their speech was judged as highly intelligible in both objective and subjective testing when assessed by a panel of naive judges. Eighty per cent of all patients were easily understood on the telephone by a naive listener. During conversational speech, quantitative parameters such as vocal amplitude and fundamental frequency were similar to normal speakers. However they demonstrated limitations in vocal range and in peak amplitude when singing or shouting. The ability to produce high quality tracheoesophageal speech from the immediate postoperative period improves quality of life and expedites the overall rehabilitation after total laryngectomy.
19例接受了一期气管食管穿刺全喉切除术的患者接受了言语能力的全面测试。所有患者在术后即刻就学会了使用气管食管发音。总体而言，由一组外行评判员进行评估时，他们的言语在客观和主观测试中都被判定为高度可理解。80%的患者在电话中能被外行听众轻松理解。在对话言语中，诸如声幅和基频等定量参数与正常说话者相似。然而，他们在唱歌或呼喊时，音域和峰值振幅存在局限性。术后即刻就能产生高质量气管食管发音的能力可提高生活质量，并加速全喉切除术后的整体康复。
