Abstract
The purpose of this study is to analyze the relation between the voice articulation and the reproduced sound characteristics by piezoelectric speaker. In this paper, the piezoelectric speaker and the dynamic speaker are compared. In order to clarify the correlation, the characteristics of consonant articulation in the car interior under car cruising noise is evaluated. The experimental results show that the consonant articulation is increased when the rising spectrogram of reproduced sound is similar to the source signal spectrogram. And, the piezoelectric speaker well reproduced the consonant voice which include the high frequency in rising spectrogram.
