Feature Extraction And Sound Pattern Analysis Of Wijaaksara Script

Abstract

Abstract Wijaksara script is a sacred script in the Balinese script structure in Balinese Hindu culture, the sound of this script is believed to create vibrations that are spiritual and magical. In Balinese script literature, Wijaksara script is a combination of the Swalatita script with the Amsa script. Wijaksara script are categorized into several groups, namely (1) Eka Aksara (Om), (2) Dwi aksara (Ang, Ah), (3) Tri Aksara (Ang, Ung, Mang), (4) Panca Aksara (Nang, Mang, Sing, Wang, Yang), and (5) Dasa Aksara (Sang, Bang, Tang, Ang, Ing, Nang, Mang, Sing, Wang, Yang). In this research, several acoustic features of sound were extracted (1) constituent frequencies, (2) waveforms, (3) sound energy. Sound recordings from 20 samples were taken and then extracted to get the constituent frequency using FFT (Fast Fourier Transform). Based on the sound waveform, the waveform and sound energy are obtained. In this study, the acoustic character patterns were obtained, namely Eka, Dwi, Tri, Panca, and Dasa. Aksara is influenced by the sound character of the eka script. The main frequencies for the sounds of the letters eka, bi, tri, and dasa are: 4.37 kHz, 7.22 kHz, 3.97 kHz. 4.18 KHZ, 11.8 KHz, while the sound energy for normal sound pronunciation conditions are: 87.31 dB, 96.72 dB, 83.25 dB, and 80.29 dB, respectively.
