The most common artificial voice source for post-laryngectomy speech rehabilitation is the handheld buzzer or electrolarynx (EL). EL speech is often described as mechanical-sounding (robotic), and typically lacks pitch variation, making it monotone and unnatural. Prior studies have shown improved perceptual ratings of speech naturalness when pitch variation is added to EL speech, and a proof-of-concept EL prosthesis has been developed to provide pitch variation and voice on/off control in relation to neck muscle electromyographic (EMG) signals. The goal of the present study was to design a new wireless version of the EMG-controlled EL (EMG-EL) that could provide a flexible mixture of manual (push button) and automatic (EMG-based) control options for voice onset/offset and pitch, and that could be manufactured at a reasonable cost for widespread patient use. This paper describes both technical and human factors considered while designing the new EMG-EL voice prosthesis.
喉切除术后语音康复最常用的人工语音源是手持式蜂鸣器或电子喉（EL）。电子喉语音通常被描述为机械感（机器人般），并且通常缺乏音高变化，使其单调且不自然。先前的研究表明，当给电子喉语音添加音高变化时，语音自然度的感知评分会提高，并且已经开发出一种概念验证型电子喉假体，以根据颈部肌肉肌电图（EMG）信号提供音高变化和语音开关控制。本研究的目的是设计一种新的无线版肌电图控制电子喉（EMG-EL），它可以为语音起始/结束和音高提供手动（按钮）和自动（基于肌电图）控制选项的灵活组合，并且可以以合理的成本制造，供患者广泛使用。本文描述了设计新型EMG-EL语音假体时考虑的技术和人为因素。
