电子喉（EL）是一种常见的康复语言援助的个人谁经历了全喉切除术，但通常缺乏音高控制，需要专门使用一只手。研究了使用颈部和面部表面肌电图（sEMG）来控制EMG控制EL（EMG-EL）的起始、偏移和俯仰的可行性。八个人谁经历了全喉切除术产生的串行和运行的讲话，使用典型的手持EL和EMG-EL，同时参加实时视觉表面肌电生物反馈。运行语音令牌与EMG-EL产生的自然度进行了检查，由10个听众相对于那些产生一个典型的EL使用视觉模拟量表。连续语音性能被评估为完全发声的单词和成功产生的停顿的百分比。视觉模拟量表评估的结果表明，个人能够使用的EMG-EL没有训练产生运行的语音被认为是自然的，产生一个典型的手持EL。所有参与者都能够通过来自多个记录位置的sEMG控制的EMG-EL产生跑步和连续语音，其中上级腹侧颈部或颏下表面位置提供了两个最佳控制位置中的至少一个。
The electrolarynx (EL) is a common rehabilitative speech aid for individuals who have undergone total laryngectomy, but typically lack pitch control and require the exclusive use of one hand. The viability of using neck and face surface electromyography (sEMG) to control the onset, offset, and pitch of an EMG-controlled EL (EMG-EL) was studied. Eight individuals who had undergone total laryngectomy produced serial and running speech using a typical handheld EL and the EMG-EL while attending to real-time visual sEMG biofeedback. Running speech tokens produced with the EMG-EL were examined for naturalness by 10 listeners relative to those produced with a typical EL using a visual analog scale. Serial speech performance was assessed as the percentage of words that were fully voiced and pauses that were successfully produced. Results of the visual analog scale assessment indicated that individuals were able to use the EMG-EL without training to produce running speech perceived as natural as that produced with a typical handheld EL. All participants were able to produce running and serial speech with the EMG-EL controlled by sEMG from multiple recording locations, with the superior ventral neck or submental surface locations providing at least one of the two best control locations.
