The simultaneous assessment of the status of the glottis opening and the position of the larynx can be beneficial for the diagnosis of disorders of voice production and swallowing. The method presented here makes use of a time-multiplex algorithm for the measurement of space-resolved transfer impedances through the larynx. The fast sequence of measurements allows a quasi simultaneous assessment of both larynx position and EGG signal in 32 channels. First results indicate a high potential of the method for use as a non-invasive tool in the diagnosis of voice dysfunction, ventricular fold phonation and swallowing disorders.
