Purpose: Diphophonia is generally defined as the perception of two pitch. To evaluate the characteristics of diplophonic voice through direct and indirect methods, we used a multi-channel system. The aim of the study is to compare the sound waveform, electroglottography (EGG), digital kymography (DKG), and two-dimensional digital kymography (2D VKG) characteristics of diplophonic voice at the same time. Second, we tried to compare convenience of discrimination between evaluations methods through reading time required for diplophonia discrimination. Methods: We performed sound waveform, EGG, DKG, 2D DKG test using multi-channel system for 1 normal adult and 14 patients with diplophonic voice (vocal folds palsy, vocal folds polyposis, and muscle tension dystonia). Quasi-periodic perturbation of cycle boundary in sound waveform, quasi-periodic variation in EGG waveform, and metacycle pattern of vocal folds structure in DKG and 2D DKG were compared. And, the read time of three evaluators was measured for each test. Results: First, diplophonia can characterize asymmetric contact of vocal cords, quasi-periodic changes of sound waveform, and metacycle pattern of EGG. Second, the asymmetric vibration patterns of diplophonia can be classified into three types with different frequencies, namely, the left-right vocal folds, anterior-posterior vocal folds, and true-false vocal folds. Third, the reading time was faster in the order of 2D DKG, DKG, EGG and sound waveform. Conclusions: The diplophonia can be classified into three types according to the asymmetric vibration region. Also, 2D DKG using MFES was relatively easy and accurate to evaluate the diplophonia compared to other evaluation methods.
