Abstract: 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.
