从评估喉功能的实验室仪器、辅助语音和说话人识别的设备以及潜在的临床诊断辅助的角度对电声门图技术进行了综述。提供了对电声门图(EGG)的电子功能的描述。相当多的重点放在了当代的研究上，这些研究的重点是使用EGG评估喉部。讨论了用于验证和辅助解释或读取EGG的方法，包括光声门图、频闪镜、超高速喉部摄影和其他。给出了用反滤波法估计声门面积和声门体积速度与EGG的关系。描述了EGG的基本模型，并将其用于预测EGG波形的特征特征。临床数据以及从喉功能正常的受试者获得的数据被分析。概述了EGG在语音处理中的应用，包括实时检测浊音、浊音和清音段以及静音间隔。EGG设备具有在某些应用中辅助语音和说话人识别系统的潜力。
The technique of electroglottography is reviewed from the perspective of a laboratory instrument for assessing laryngeal function, a device to assist speech and speaker recognition, and as a potential diagnostic aid in the clinic. A description of the electronic functioning of the electroglottograph (EGG) is provided. Considerable emphasis is given to contemporary research which has focused on laryngeal assessment using the EGG. Methods for validating and aiding the interpretation or reading of the EGG are discussed, including photoglottography, stroboscopy, ultrahigh-speed laryngeal cinematography, and others. The relationship of the EGG to glottal area and glottal volume velocity estimated by inverse filtering is presented. An elementary model of the EGG is described and used to predict characteristic features of the EGG waveform. Clinical data as well as data obtained from subjects with a normal functioning larynx are analyzed. Applications of the EGG to speech processing are outlined, including real-time detection of voicing, voiced and unvoiced speech segments, and silence intervals. The EGG device has potential for assisting speech and speaker recognition systems in certain applications.
