Abstract:
Pirith is believed as a protective doctrine preached by the Load Buddha in Pali language. The aim
of this study is to analyze acoustic properties of Pirith using computer-aided methods and identify
special characteristics and patterns. In this study, two methods were used to identify special
characteristics of Angulimala Sutta. First method calculates voiced to unvoiced ratio using zero
crossing rate and energy content associated with the acoustic signal while second method
recognizes vowel distribution using first and second formant frequencies. Results of the first
method indicates approximately 96% of frames are voiced while the second method suggests
approximately of vowels concentrate in the square region of
and demonstrating when chanting the Angulimala sutta most of the time the tongue
