目的：电喉（EL）是一种广泛使用的咽喉语音设备，但它需要人工操作，产生的声音通常具有恒定的基频。肌电图控制的肌电信号（EMG-EL）。设计并实现了通过动态音调调制提供免提控制。方法：3名接受全喉切除手术的参与者和4名声音正常的参与者通过多基线、连续阶段协议进行肌电图-电图语音训练。通过3个测试探针建立基线性能，然后进行多个小时的训练。结果：在训练结束时，所有参与者都学会了根据发音启动、维持和终止肌电图激活，并且大多数人能够调节音高来产生语调对比。在完成测试/训练方案后，3名接受全喉切除术的参与者中有1名被鼓励在其住所独立使用肌电图。该参与者将其表现维持了6周，并成功地使用肌电图进行电话交流。结论：我们的研究结果表明，一些喉切除术参与者和声音正常的人可以在几个小时内学会使用肌电图- el设备产生免提语音，并且通过随后的培训课程可以获得设备控制（特别是音调调节）的显著额外收益。
Purpose: The electrolarynx (EL) is a widely used device for alaryngeal speech, but it requires manual operation and produces voice that typically has a constant fundamental frequency. An electromyographically controlled EL (EMG-EL).was designed and implemented to provide hands-free control with dynamic pitch modulation.Method: Three participants who underwent total laryngectomy surgery and 4 participants with normal voice were trained to produce EMG-EL speech through a multiple-baseline, successive-stage protocol. Baseline performance was established through 3 testing probes, followed by multiple hour-long training sessions.Results: At the end of the training, all participants learned to initiate, sustain, and terminate EMG-EL activation in correspondence with articulation, and most were able to modulate the pitch to produce intonational contrasts. After completing the testing/training protocol, 1 of the 3 participants, who underwent total laryngectomy was encouraged to independently use the EMG-ELat his residence. This participant sustained his performance for an additional 6 weeks and also used the EMG-EL successfully to communicate over the phone.Conclusions: Our findings suggest that some participants with laryngectomies and vocally normal individuals can learn to produce hands-free speech using the EMG-EL device within a few hours and that significant additional gains in device control (particularly pitch modulation) are attainable through subsequent training sessions.
