This study was done at the ENT Department of the Ege University Medical Faculty on twenty trainee singers. Using the two-channel signal processing method, the electroglottographic (EGG) signals and the voice signals were digitized with an analog-digital converting card during an ascending and descending glissando exercised by the trainee singer. These signals were recorded on the computer's hard disk and the obtained data was analysed. It has been determined that the EGG signals were more irregular the singing formant of the voice signal was very weak or absent and the change of register was more significant in less trained singers. This method can be used to evaluate objectively the change of voice registers in the training of the singers and be easily performed by adding an analog-digital converting card to a PC computer, without the need of expensive modern devices.
本研究在伊兹密尔埃杰大学医学院耳鼻喉科对20名实习歌手进行。采用双通道信号处理方法，在实习歌手进行上行和下行滑音练习时，通过模拟数字转换卡将电子声门图（EGG）信号和语音信号数字化。这些信号记录在计算机硬盘上，并对获得的数据进行分析。已确定，在训练较少的歌手中，EGG信号更不规则，语音信号的歌唱共振峰非常微弱或不存在，且声区变化更显著。这种方法可用于客观评估歌手训练中声区的变化，并且通过在个人电脑上添加模拟数字转换卡即可轻松实现，无需昂贵的现代设备。
