声带振动的间接观察，可以从声门气流波形使用反向过滤口腔气流的非侵入性技术。其目的是评估自动逆滤波程序？逆？即基于线性预测分析的音高异步方法。用Rothenberg面罩中的压差传感器记录口腔气流。同时记录口内压、电声门图（EGG）和声信号。17名健康女性的[ba：pa：pa：pa：p]声音正常、柔和、响亮。从逆过滤使用手动程序（声门企业系统）和自动程序进行的结果进行了比较？逆？提取声门气流波形参数峰值流量、最小流量、峰间流量和最大负流量导数。两种反滤波方法的一致性很高，反映在每种气流的相关系数都很高。
Indirect observations of the vocal fold vibrations can be made from the glottal airflow waveform using the non-invasive technique of inverse filtering the oral airflow. The aim was to evaluate the automatic inverse filtering program ?Inverse?, that is, a pitch-asynchronous method based on linear prediction analysis. Oral airflow was recorded with a differential pressure transducer in a Rothenberg mask. Intraoral pressure, the electroglottographic (EGG) and acoustic signals were recorded simultaneously. Seventeen healthy women produced [ba:pa:pa:pa:p] in normal, soft and loud voice. Comparisons were made between results from inverse filtering performed using a manual procedure (Glottal Enterprises System) and the automatic program ?Inverse?. The glottal airflow waveform parameters peak flow, minimum flow, peak-to-peak flow, and the maximum negative flow derivative were extracted. High agreement between the two inverse filtering procedures was reflected by high correlation coefficients for each of the airfl...
