喉切除术后言语康复中最常见的人工声音来源是手持蜂鸣器或电喉器（EL）。人工智能语音通常被描述为机械声音（机器人），通常缺乏音高变化，使其单调而不自然。先前的研究表明，当将音高变化添加到EL语音中时，语音自然度的感知等级得到改善，并且已经开发出一种概念验证的EL假体，以提供与颈部肌肉肌电图（EMG）信号相关的音高变化和语音开关控制。本研究的目标是设计一种新的无线版肌电信号控制的肌电信号（EMG-EL），它可以提供灵活的手动（按钮）和自动（基于肌电信号）控制语音开始/偏移和音高的选择，并且可以以合理的成本制造，以供广泛的患者使用。本文介绍了在设计新型肌电图声假体时所考虑的技术因素和人的因素。
The most common artificial voice source for post-laryngectomy speech rehabilitation is the hand-held 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.
