Abstract in different language:	This paper deals with the facial surface vibration measurement performed by three different methods. Facial vibrations were measured during performing the resonance voice exercises with different shape of vocal tract or with different length of the resonance tube. Vibrations were measured on the upper lip by vibrometer and on the ala of nose by accelerometer. The amplitude of oscillation was also monitored by high speed camera in the direction x and y axes and also total amplitude. Correlations between all three methods showed a significant agreement in measurement. Two-way Analysis of Variance (ANOVA) with the type of vocal tract and pitch were applied. It revealed the significant differences of amplitudes of vibration dependent on the pitch and the vocal tract type.
