Modelling of the Arabic Plosive Consonants Characteristics Based on Spectrogram

The aim of this study is to determine the place of articulation for Arabic phonemes by subjects on non-arabic spoken language namely Malay. Every phoneme must be pronounced accurately in order to obey the rule of tajweed of holy Quran. By using Fourier analysis technique, the sound waveform is transform into spectrum which is frequency representation of the signal. The spectrogram is used to determine the formant frequency. The spectrogram for each subject is observed to determine its formant frequency. This study shows that second and third formant frequency (F2 and F3) increased as the articulation is made towards into the mouth.
