Abstract：
Currently, there is no consensus on the characterization of the human voice. The objective of the present study is to describe the myoelectric behavior of the extrinsic musculature of the larynx in 146 people with normal voice (Spanish speakers), aged between 20 and 50 years old. Different vocal tasks were recorded using a surface electromyograph (SEMG). In all vocal tasks, it was observed that women had higher activation (µV) in the suprahyoid and sternocleidomastoid muscles than men, while men had higher activation in the infrahyoid muscles. SEMG is a valid procedure to help define normal vocal characteristics in the studied population, providing reference values during clinical examination. However, it is necessary to adopt a universal system of assessment tasks and standardized measurement techniques to allow for comparisons with future studies.
摘要：
目前,关于人类声音的表征没有共识。本研究的目的是描述146名声音正常的人（西班牙语使用者）的喉外部肌肉组织的肌电行为，年龄在20至50岁之间。使用表面肌电图仪（SEMG）记录不同的发声任务。在所有声乐任务中，据观察，女性在舌骨上肌和胸锁乳突肌的激活（µV）高于男性，而男性在舌骨下肌肉有更高的激活。SEMG是一种有效的程序，可以帮助定义所研究人群中的正常声音特征，在临床检查中提供参考值。然而,有必要采用通用的评估任务系统和标准化的测量技术，以便与未来的研究进行比较。
