To objectify the vocal fold functioning we opted for a method of processing the electroglottographic (EGG) signal. This study with 7 normal and 12 pathological voices presents the results of measurements over the chest register as a function of voice intensity and frequency. Reproduction measurements show that at least 5 measurements per intensity/frequency pair are needed to get a reasonable estimation of the EGG parameters. The averaged results over about 20 measurements in the chest register showed differences for some parameters for subjects in the most different categories. To get more consistent results we recommend to improve the measurement protocol and adjust the parameters.
为了客观评估声带功能，我们选择了一种处理电子声门图（EGG）信号的方法。这项针对7名正常嗓音者和12名嗓音病理患者的研究呈现了胸声区测量结果，这些结果是嗓音强度和频率的函数。重复性测量表明，对于每个强度/频率对，至少需要进行5次测量才能合理估计EGG参数。胸声区约20次测量的平均结果显示，不同类别受试者的某些参数存在差异。为了获得更一致的结果，我们建议改进测量方案并调整参数。
